KUKA's youBot Mobile Manipulator Unveiled

In a unique step for an industrial robot manufacturer, robotics giant KUKA has released a mobile platform (wow) with open interfaces (wow) that include several open source (wow) software modules for education and research (wow). Yes, that's "wow" four times!

The robot is clearly a big move for KUKA, known for more traditional industrial systems, but perhaps even more significant, it's also a departure from the proprietary software, closed interfaces, and stationary robots typically used by all major industrial robotics companies, including ABB, Fanuc, and KUKA itself.

The KUKA youBot was introduced at the Automatica conference in Munich, Germany this week. Its hardware was custom developed by KUKA. The software was created as part of the European Best Practices in Robotics, or BRICS, project, funded under the EU's FP7 robotics framework.

It is too early to say whether the youBot is a forerunner of a bigger trend, but it makes for some amusing Friday afternoon musing: Industrial manipulators have been mostly stationary systems. Will they now start moving around?

Is this the beginning of a new class of robots, bridging the gap between today's industrial and service robots? And is industrial robotics moving towards more open standards, or are we moving towards a split into specialized hardware and software companies, similar to what happened in the PC industry? 

Either way, KUKA's youBot looks promising:

Hardware Specs:

youBot arm: Serial kinematics with 5 degrees of freedom (655mm height, 0.513 m³ work envelope, 6kg weight, 0.5kg payload, 0.1 mm repeatability, 80W power limit (for safety)). Fix axes serial structure with a two finger gripper at the flange. Links are made of very lightweight, but stiff magensium cast. Custom, lightweight motor-gear combinations.

youBot gripper: detachable, 2-finger gripper attached to the arm (10mm stroke/finger = 20m opening stroke; different mounting allows to grip objects up to 70mm diameter)

youBot platform: omnidirectional mobile platform with 4 KUKA omniWheels (530x360x106mm, 15 mm clearance, 20kg total weight, 20kg payload, 0.8m/s speed, EtherCAT communication, 24V)

Energy supply: one set of two batteries (Two 12 V, 5 Ah, maintenance-free lead acid rechargeable batteries; approximate runtime: 90 minutes) embedded into mobile platform

On-board PC: mini ITX board form factor (embedded CPU, passively cooled, 512 MB RAM, 4 GB Compact Flash, WLAN, USB), embedded into the mobile platform

Software Specs:

Open source robot controller with open interfaces (position, velocity and current control)
BRIDE (BRics Integrated Development Environment) based on Eclipse to simplify application development
BROCRE (BRICS Open Code Repository) offers interoperable interfaces and best practice algorithms libraries:
    - BRICS_MM for mobile manipulation
    - BRICS_3D for 3D perception and modelling
    - BRICS_RN for robust navigation)
Blender simulation model
Sample applications

The video below features the current prototype. The final version will have magnesium casings for the arm to make it lighter, re-designed covers for the body that allow for easier battery access and - obviously - omniwheels in KUKA-orange.

KUKA will start delivery 1. Nov 2010 for Germany (1. Dec 2010 for Europe; 1. Mar 2011 for USA/Asia). Prices are EUR 19'990 (USD 24'200) for the complete robot. Arms are sold separately for EUR 12'990 (USD 15'700), the omni-directional base for EUR 8'990 (USD 10'900), with significant discounts (20-25%) for early birds and universities.

Project Rezero: Ball Balancing Robot With Style

rezero ballbot

A few weeks ago we reported on a ball-balancing robot by Masaaki Kumagai at Tohoku Gakuin University in Japan. Interestingly, the same challenge has been taken up by a team of students at the ETH Zurich in Switzerland, who have just presented their Rezero robot to the public.

The Focus-Project team Ballbot consists of eight future mechanical engineers, studying at the ETH Zurich, two electrical engineers studying at the ZHAW as well as the Industrial Designers educated at ZHdK. Through the combination of our skills and ideas we aim to complete an unprecedented project which develops a new concept of movement. Our team with its task is supervised by Prof. Dr. Roland Siegwart, Director of the ASL at ETH Zurich

Watch:

Unlike Kumagai's ballbot, one focus of the Rezero is design:

Rezero is meant to entertain and impress. It is supposed to create emotions. It will be able to interact with a small group of people, react on attractions and in doing so create a hands-on experience with the Ballbot technology. The Ballbot will be an ambassador of its own movement skills. Its dynamic hull even allows Rezero to show and create emotions. Imagine Rezero breathing, being curious or frightened. And even waking up or going to sleep by revealing or retracting its sphere.

Another focus is improved dynamics: To push the boundaries of current ballbots, the team uses a custom-made motor controller in combination with high-performance engines and a specially coated ball. This allows Rezero to move fast - at speeds up to 3.5m/s and with inclinations up to 17 degrees - and to perform unique movements, such as moving with high inclinations while simultaneously rotating around its vertical axis.

The Rezero project is supported by Disney, which just opened their Disney Research lab at ETH Zurich earlier this year -- only the second joint lab with a university (the other is Disney Research in Pittsburgh with CMU).

iRobot Roomba 560 vs. Neato XV-11

Now that we’ve reviewed both the iRobot Roomba 560 and the Neato XV-11, you’re probably wondering which one you should get. There’s no easy answer, but in this post we’ll highlight the features of each robot and the differences between them, so that you can decide which one is right for you.

If you haven’t read our individual reviews of each robot, you can get lots more detail at the following links:

BotJunkie Review: Neato Robotics XV-11
BotJunkie Review: iRobot Roomba 560

And, there will be jousting, after the jump.

-Design

Both robots are approximately the same size, with two driver wheels underneath and a touch sensing bumper at the front. The Roomba is round, allowing it to turn all the way around in place, while the XV-11 has a square front to help it get into corners more effectively.

The XV-11 is slightly taller:

This means that if you have furniture that’s within that height difference, the Roomba will clean underneath it but the XV-11 won’t. The XV-11 is just under 4 inches tall, while the Roomba is a bit over 3.

Both robots have a built-in carrying handle. The XV-11 is a little bit heavier. They both seem very solid and robust (although you probably want to avoid dropping them), and both come with a one year warranty.

Both robots include one button cleaning, meaning that whatever else they can do, at the very least you can just push the big “clean” button on them and they’ll go vacuum. The Roomba 560 has additional dedicated displays for scheduling cleaning times, while the XV-11 has a small multipurpose LCD display.

-Features

Both robots come with charging docks that they can return to autonomously. The Roomba’s dock is drive-on, which means that the robot charges by driving onto a little platform. The XV-11’s dock is drive-up, which means that the robot presses against the dock. The XV-11’s dock includes a storage compartment for the power adapter, which is a useful feature, since you can store the adapter inside the dock if you don’t need the extra power cord length. Both robots will attempt to ’snug’ back up to their charging contacts if they get accidentally moved.

The Roomba 560 and the Neato XV-11 both allow for on-board scheduling. You can set different times for each day of the week, and the robot will undock, clean, and redock to recharge itself. It’s relatively easy to program this on both robots, although the XV-11’s LCD makes it a bit easier.

Due to its LCD, the XV-11 has a distinct advantage when it comes to user communication. The screen tells you if you need to perform maintenance tasks, or what to do if the robot isn’t doing what it’s supposed to be doing. The Roomba will sometimes speak in a female voice when it needs assistance, but for more obscure technical issues it just beeps, and you need to keep track of the number of beeps and look up what they mean online, which is far less convenient.

Both robots come accessories that you can use to keep them away from certain areas. The XV-11 uses a magnetic strip (you get 15 feet of it and can buy more for $30) that you place on the floor, and the robot will clean up to it but not go over. You can cut the strip up, and it sort of bends enough to make curves. The Roomba uses Virtual Walls, which are little towers about the size of a coffee cup that project infrared beams which the robot won’t cross over, so you can leave them up around doorways and stuff even when the robot isn’t vacuuming. The beams will reach out to about 8 feet, and the Virtual Walls run on batteries. The 560 comes with two, and buying another one will cost you $40.

-Cleaning

The Roomba and the Neato XV-11 use significantly different techniques to vacuum areas. The Roomba uses a variety of cleaning behaviors to cover a room, using input from its sensors to decide where to go next. It doesn’t know where it has or has not been in the absolute sense, but on average, it will cover each area of a room 3-4 times, which helps it to clean more thoroughly.

The XV-11, on the other hand, has a laser sensor that creates a map of walls, doorways, and obstacles. The robot then plans a route to cover the entire area efficiently, generally with a single pass over most points.

We should point out that neither the XV-11 nor the Roomba is a total replacement for a human wielding an upright vacuum with a hose attachment. Rather, they’re maintenance tools, designed to minimize the amount of vacuuming that you have to do. That said, we found both robots to clean very effectively on hardwood, comparable to a conventional upright vacuum over most of the floor. Because of their shapes, however, the robots aren’t quite as good close to obstacles, along walls, and in corners.

The XV-11 is better at cleaning along walls and corners in most cases, since its square front allows it to get in closer, although it doesn’t always get into corners in the ideal orientation. Because the Roomba is round, it relies on a spinning brush to sweep into corners, which is less effective than getting the entire vacuum in there. It’s worth noting, though, that this spinning brush extends beyond the reach of the vacuum, outside the body of the robot, which means that the Roomba can (sort of) clean beyond its own chassis, while the XV-11 can’t. The effectiveness of the spinning brush is mediocre at best, however, since it often just kicks dirt somewhere else where the Roomba may or may not get later. Basically, neither robot can make up for the hose attachment on a conventional upright vacuum when it comes to tight areas.

On carpet, both the XV-11 and the Roomba did fairly well, although not as good as an upright. The Roomba cleaned slightly better in general, and significantly better when it came to pet hair, probably because of its bristle brush. The rubber brush on the XV-11 tended to leave streaks of pet hair behind it. Neither robot got pet hair completely cleaned up, though, and they did especially poorly around table and chair legs. Also, iRobot has pointed out that crossing over carpet from multiple angles changes the nap of the carpet and is better for getting dirt out, which I tend to believe… The XV-11 cleans in a single pass.

The XV-11 is significantly faster than the Roomba, about four times faster, cleaning my living room in 12 minutes as opposed to the Roomba’s 45. This difference will increase as the robots are asked to clean larger rooms or more rooms. The XV-11 doesn’t move faster, but since it doesn’t cover most areas more than once, it’s done much faster. Also, it knows exactly where its dock is, and doesn’t have to spend time searching for it after it’s finished. Of course, if you’re taking advantage of the scheduling feature, these vacuums are running by themselves when you’re not home, in which case speed (and noise) may not matter nearly as much. In this case, the question changes from is it faster to how much area can each robot cover per charge, how long does it take to recharge, and how effectively can it resume coverage of multiple rooms? The XV-11 has a pronounced advantage here, because it cleans more efficiently: It spends significantly less time on each room, is better at finding its way from room to room (since it can see doorways), can more reliably find its way back to its charging dock if it needs to (since it creates a map), and then can return to exactly where it left off and finish cleaning without any redundancy in coverage. Some models of Roombas include Lighthouse technology which helps them clean multiple rooms more efficiently, but the 560 does not.

The XV-11 seems significantly louder than the Roomba; both are significantly quieter than an upright vacuum. We’re waiting for exact decibel numbers.

Both robots have minimal issues cleaning entirely autonomously, meaning that in general, you really can just let them do their thing from start to finish without having to worry about them getting lost or stuck.

-Maintenance

Both robots require you to empty their dustbins on a regular basis. Depending on how many rooms you have them clean, and how dirty your floors get, this could be anywhere from every cleaning to every three cleanings or so. Both robots will inform you when their dustbins need to be changed, so it’s not something you really have to worry about… Although it’s better to empty them before they fill completely, especially if you have the robots clean autonomously.

The dustbin on the XV-11 is marginally easier to access than the one on the Roomba, since it lifts out of the top of the robot instead of out of the back. Also, the XV-11’s air filter keeps the dust in when you lift the bin out; you remove the filter to empty the bin. The Roomba’s bin doesn’t have a cover like that, so there’s the potential to make a huge mess unless you pull the bin out carefully and keep it in the correct orientation. The XV-11 also has a larger dustbin, but I wouldn’t call it significantly larger.

The air filters on both robots are easy to access and replace, being integrated into the dust bins themselves. Replacement filters for the XV-11 cost $19 for 6, and for the Roomba it’s $19 for 3.

The XV-11 is much better at keeping itself clean as it cleans, especially when it comes to hair (pet and otherwise). I have a couple cats, and while the Roomba was significantly better at picking up cat hair, it also got a lot of cat hair wrapped around its bristle brushes, as well around the bearings holding the brushes in place. After just a few vacuumings, you’ll need to take the brushes and bearings out and clean them by hand, which is a dirty and annoying process. iRobot includes a tool to help with this, but I’ve often had to resort to scissors and brute strength to get the hair out of the bristle brush. The XV-11, on the other hand, while not as good at picking up pet hair, remains very clean, on both its brush and bearings. After 3 rounds of my living room, the Roomba was very dirty and tangled underneath, while the XV-11 looked brand new.

Lastly, there are maintenance tasks that you shouldn’t have to do very often, or (ideally) at all, like replacing brushes, bearings, and batteries. We didn’t get a chance to test the XV-11 to this point, but my guess is that the XV-11 would be more resistant to bearing damage (something I’ve experienced with my own personal Roomba), simply because not as much stuff gets caught up in its cleaning system.

Both iRobot and Neato offer replacement components for their robots. iRobot’s website has nearly every component for the robot available, while Neato mostly focuses on accessories. I didn’t try to take either robot apart, so I can’t comment on how easy it is to replace major components, but I like the fact that iRobot gives you the option to try to fix things yourself.

-Overall

The Neato XV-11 is currently on pre-order for $400, to be available “this summer.” The iRobot Roomba 560 is available now for $350. However, the Roomba 560 does not include the Lighthouse multi-room technology. To get that, you’d need to upgrade to the Roomba 570 for $450, which might be a more realistic robot to compare the XV-11 to in terms of multi-room cleaning capability. And even then, the XV-11 is still likely to be significantly better at cleaning multiple rooms due to its mapping technology.

So, to summarize:

-Both robots clean hardwood equally well, about as well as a traditional upright vacuum.
-The Roomba cleans carpet noticeably better than the XV-11, and is significantly better at picking up pet hair. Neither robot is as good at these tasks as a traditional upright vacuum.
-The Roomba requires significantly more maintenance than the XV-11, especially if it picks up hair of any kind.
-The XV-11 cleans rooms about four times as fast as the Roomba.
-The XV-11 is significantly better at cleaning multiple rooms than the Roomba.
-The XV-11 seems louder than the Roomba.
-The fact that the Roomba uses cleaning behaviors derived from foraging insects is very cool.
-The fact that the XV-11 uses a laser to map rooms is very cool.

There are a few other things to potentially consider… If cost is an issue, iRobot sells Roomba models that are less expensive than the 560. If you only need to clean one or two rooms, and don’t need the scheduling feature, you could get a Roomba 530 for $300.

Also, iRobot has been selling Roombas for a long time, while Neato is introducing a new product. The fifth generation of Roombas embodies many years of improvements and refinements while the XV-11 has yet to prove itself as a commercial product. That said, the mapping technology in the XV-11 is very impressive, and I feel like irrespective of which robot makes a better vacuum, there’s a lot of potential there.

What it comes down to, though, is that both the iRobot Roomba 560 and the Neato XV-11 are solid autonomous robot vacuums that use different techniques and technologies to get your floor clean and keep it that way without you having to lift a finger.

And once again, I’d encourage you to read our individual reviews of each robot, since there are lots more details (plus more pictures and video):

Oh yeah, and here’s the jousting:

Robot Bus Moves People, No Driver Needed

robosoft roburide

French company Robosoft has unveiled what it calls a "cybernetic transport system." The robuRIDE carries 30 passengers and reaches 24 kilometers per hour, driving autonomously using differential GPS and onboard sensors.

robosoft roburideThe vehicle weighs 3 metric tons, or 5 metric tons fully loaded. A 380-volt pack of lead acid batteries gives it 8 hours of autonomy. In automatic mode, it can follow a pre-recorded path. To drive it manually, you use a game controller.

A safety system relies on a laser scanner to avoid collisions. In the video below, the researcher demonstrates it by putting his body on the line. The vehicle detects him and slowly decelerates, stopping about 2 meters from him. Even if this system fails, a soft foam bumper stops the vehicle if it hits something, or someone.

Now my favorite part: According to the video, you can regulate the vehicle's cabin temperature by "opening windows and [using] fans." Elegant engineering.

This is the system's second generation, and the video shows a test conducted in France last month. The robuRIDE is part of Rome's Cybernetic Transport System, a program to implement a high-tech transportation infrastructure at the city's new convention center. Is this the future of mass transit?

Vincent Dupourque, CEO of Robosoft, says:

We have completed the 2nd generation of our robuRIDE, used to implement Cybernetic Transport Systems. It can reach 24 km/h with 30 passengers, and has a dynamic accuracy of a few centimeters, thanks to the hybrid navigation system based on GPS, inertial and odometry.

This video has been done during Factory Acceptance Tests of the robuRIDE for ROME Cybernetic Transport System, in May 2010, in Dax, Biarritz and Bidart. We explain here the vehicle and how it works, show how it can be transported from one site to another, and also some users give their first impressions.

Monkey Controls Advanced Robot Using Its Mind

university of pittsburgh brain machine interface

In a remarkable demonstration of brain-machine interface technology, researchers at the University of Pittsburgh have taught a monkey to use just its thoughts to control an advanced robotic arm and perform elaborate maneuvers with it.

It's not the first time a monkey with sensors implanted in its brains has controlled machines with its mind. But this seven-degrees-of-freedom robot arm is probably the most complex system a monkey has ever mastered with its thoughts alone.

Researchers have long been working to put the brain in direct communication with machines. The hope is one day brain-machine interfaces will allow paralyzed people to operate advanced prosthetics in a natural way. Recent demonstrations have seen animals and humans controlling ever more complex devices.

But the experiments at the University of Pittsburgh, led by Dr. Andrew Schwartz, a professor of neurobiology, appear to involve an unprecedented degree of complexity in terms of the robotic arm, the level of control, and the difficulty of the manipulations demonstrated. Watch:

The video above shows the experiment. Note the monkey on the right side of the screen. It uses its right arm to tap a button. (Its left arm is gently restrained inside a tube.) This triggers the robotic manipulator labeled DENSO [left side of the screen] to position a black knob at an arbitrary point in space. The monkey then controls its articulated robotic arm to grasp the knob.

After gently touching the knob, the monkey places its mouth on a straw: it then gets a drink reward. (Actually, the animal places its mouth on the straw before even touching the knob; that's because it has learned, from repetition, that it's about to get the reward.) After that, both robotic arms reset. Again, the monkey taps the button, waits for the knob's new position, and readily and precisely moves its robotic arm to get a drink.

In this experiment, the monkey received two brain implants: one in the hand area and another in the arm area of its motor cortex. The implants monitor the firing of motor neurons and send this data to a computer, which translates the patterns into commands for the robotic arm.

In a previous study two years ago, Dr. Schwartz and his team taught a macaque to control a simpler mechanical arm to feed itself. This was a four-degrees-of-freedom arm with shoulder joints, an elbow, and a simple gripper.

Now the researchers have added three more degrees of freedom by adding an articulated wrist, which can perform roll, pitch and yaw movements. And the arm itself was replaced by a larger and nimbler manipulator. Although the video doesn't show it, the monkey can not only touch the knob but also precisely turn it by rotating the mechanical wrist.

Dr. Schwartz was kind enough to share this much with us, but he says more details will have to wait until he and his colleagues publish their results. We'll be waiting.

Vgo Telepresence Robot

In what may be (but probably isn’t) just a coincidence, a third telepresence robot has made a (pre) commercial appearance in as many weeks. This robot is called Vgo, and… Well, it does telepresence. Stop me if you’ve heard this before, but you get on your computer on one end, connect to the robot, and then drive it around while looking through its cameras. Sensors keep you from running into stuff or falling down stairs, and it’ll run all day on one battery charge. The biggest news, at this point, is that the Vgo is only supposed to cost $5000. Plus a mandatory support contract of $1200 a year. So, $6000.

The Boston Globe has a nice piece on Vgo… There aren’t many more technical details, but I did find this interesting:

Two analysts I spoke with differed on the potential for robotic videoconferencing. Rob Enderle, a technology analyst at the Enderle Group who has written about the slow spread of traditional videoconferencing systems, said that “the closer we get to simulating being there, the better an alternative to travel it will become.’’

But Dan Kara, president of the publishing company Robotics Trends in Framingham, said, “I’m not quite sold on mobile telepresence. How is it that much better than having someone at the remote site carry around a netbook computer with a free copy of Skype on it?’’

The whole minion+laptop+Skype thing is exactly the point we made back when Anybots’ QA was introduced at CES for $30k. Obviously, a telepresence robot is much better than minion+laptop+Skype, but the question is, is it really that much better in terms of cost effectiveness? At the $6k price point, perhaps. Or maybe that’s not the question… Maybe the question should be, how much hardware is required to simulate being somewhere else to the extent that is necessary to make paying for a robotic telepresence solution a practical idea? I don’t have the answer, but hopefully the consumer market will, now that there are (or soon will be) three different telepresence robots available for people to purchase.

iRobot Demonstrates New Weaponized Robot

UPDATE: Some readers argued that the APOBS, or Anti-Personnel Obstacle Breaching System, developed in a joint program of the U.S. Army and Navy, is not, technically, a weapon, because it's not an anti-personnel system but rather a system used against obstacles. Perry Villanueva, the project engineer for the APOBS program on the Army side, says the APOBS "is not a weapon in the traditional sense, but it is a weapon." Other readers wondered how the rocket compensates for things like wind. Villanueva says that is more of an operational issue. "With high winds it is up to the soldier to position it so it will have a high probability of landing on its target."

iRobot released today new video of its Warrior robot, a beefed-up version of the more well-known PackBot, demonstrating use of the APOBS, or Anti-Personnel Obstacle Breaching System, an explosive line charge towed by a rocket, with a small parachute holding back the end of the line. The APOBS, iRobot says, is designed for "deliberate breaching of anti-personnel minefields and multi-strand wire obstacles." It can clear a path 45 meters long and 0.6 meters wide.

iRobot worked with the Naval Air Warfare Center Weapons Division (NAWCWD), the U.S. Army Tank Automotive Research, Development, and Engineering Center (TARDEC), and the U.S. Marine Corps Forces Pacific Experimentation Center (MEC) for this demonstration. It took place in November 2009 at the Naval Air Weapons Station China Lake in California's Mojave Desert.

Although it may concern those who don't like the arming of robots, it makes great eye candy for those who like robots, rockets, and explosions.

Now, let me say this: I am neither condoning nor condemning the weaponization of robots, just stating the facts that I am aware of.

In early 2009 a handful of defense related companies came to Thailand to demonstrate their latest war toys to the local generals. One of those companies was iRobot, and as I have many friends who work for iRobot and I was living in Bangkok at that time, I got to meet up with them to see one of the toys they brought: a Warrior.

At the time, the Warrior hardware was complete, designed to carry 150 pounds, but I've seen it lift people standing on it. Unfortunately, and understandably, many of my questions about it were answered with "we aren't sure we are allowed to answer that." I couldn't get an answer as to how much it would cost, but I was given the impression that it's more than $100,000 per unit.

Back in the day, the founders of iRobot had been against the weaponization of robots. Perhaps business and financial pressures are pushing the boundaries. Indeed, the military market is becoming ever more important, according to the company's first quarter results. Finances were very tight in 2009, so iRobot probably sees military systems as a market they'll have to explore and expand.

Updated by Erico Guizzo, June 1, 2010 : Added details on APOBS; edited comments on iRobot financials and weaponized robots. June 2: Added details on demonstration participants, date, and place. June 3: Added more details on APOBS.

Aggressive Quadrotor Maneuvers Are Totally Nuts

uav drone grasp lab

Every once in a while, we get to see a video of a robot doing something that makes us think "OMG WTF THAT’S WICKED CRAZY IMPOSSIBLE!!!" And then, we remember that crazy stuff is entirely possible, because we’re talking about robots, and we have to stop thinking about what is and is not possible in terms of human capabilities.

This is one of those videos:

I don’t have much more info for you than what’s in the video, unfortunately, but it does look like these maneuvers (while obviously autonomous) are currently restricted to an area with a whoooole bunch of sensors that can tell the robot where it is with an accuracy (and frequency) that’s probably pretty impressive.

If you remember, we’ve seen both autonomous acrobatics and autonomous landing on slopes by UAVs, but nothing like this… The precision of these maneuvers is just totally completely nuts.

Willow Garage's PR2 Robots Graduate

It's graduation season, and yesterday Willow Garage, a start-up dedicated to accelerating the development of personal robots, sent its first graduation class of PR2s off into the world. These 11 robots are heading out to universities and labs in Germany, Japan, Belgium, and the United States, where they will help researchers figure out how robots can assist the elderly and the autistic, navigate buildings and open doors, and help people do house chores, to name just a few of the many projects in the works. At the graduation party in Menlo Park, Calif., some of the researchers told IEEE Spectrum about their plans for these robots. And then it was time to celebrate.

And here's Willow Garage showing off the PR2 at a pre-party press conference. The video was recorded by Spectrum's Erico Guizzo, who was embodied as a Texai, a telepresence robot also created by Willow:
