Robot Puts Box On Head

Robots have a tendency to move rather a lot like, um, robots. How dare they. The smooth and natural motions that we humans are so proud of comes from a combination of many different motions all at once: if you pick something up, you're generally not just using your arm like a robot does, but rather, subtly moving your arms, wrists, hands, torso, and even your head. With a new movement algorithm, iCub is learning to move in a much more human-like manner, even with complex motions.

Disney Rapid Design Tool Creates Mechatronic Characters

The typical approach to adding actuated joints and additional degrees of freedom to a robot is slapping additional servos and motors on there. And that's fine, except that it adds weight and cost and complexity. A little bit of cleverness with gears can go a very long way, and Disney Research has developed a new rapid design tool that can create sophisticated mechatronics that operate with just one motor.

Video Friday: KAIRO Can Rescue You, Remote Control Humans, and Roboboat 2013

Robots are serious business. Very serious. They're expensive. They're complex. They're expensive. They're hard to build and hard to program. They're expensive.

For all of these reasons, they make really, really great toys, and the more expensive they are, the more fun they are to play around with. I'm sure that most of the videos of serious business robots being played with by the people who are responsible for them never see the light of day (serious business, remember?), but we love it when every once in a while, a video of some roboticist saying (metaphorically, of course) "hold my beer while I try this" shows up on the Internet for us to enjoy. Like, hey, we've got a robot snake with wheels, let's harness it up and see if it can pull us around! YEAH!

Startup Spotlight: Prensilia Developing Robot Hands for Research, Prosthetics

This is the fifth post in our Startup Spotlight series featuring new robotics companies from around the world. We're inviting representatives from these startups to describe their technologies and how they see the marketplace. The views expressed here are solely those of the author and do not represent positions of IEEE Spectrum or the IEEE.

Researchers have long been trying to build robotic hands that mimic the extraordinary capabilities of the human hand. The goal has been a device with size and weight similar to our own hands, capable of performing multiple grasping motions, and powered by advanced controllers. Such robot hands could help to advance important research areas, such as prosthetics, neural engineering, rehabilitation, humanoid robotics, and human-machine interfaces.

Video: Boston Dynamics' Atlas Robot Revealed

Last Thursday, I went to see the unveiling of Boston Dynamics' Atlas robot. This imposing humanoid machine will be used in the DARPA Robotics Challenge (DRC), which aims to develop robotics hardware and software that can be used to handle extreme emergencies, such as an accident at a nuclear power plant. Last week we brought you some photos and specs: today we have video for you, including interviews with some of the key figures and team members involved in the DRC.

Robot Frogs Trick Females in 'Bizarre' Example of Evolution

In my admittedly limited experience, no species (especially not humans) is particularly clever when it comes to properly interpreting mating calls. Let’s take the túngara frog as an example, because someone made a robotic one, so we can talk about it. The female túngara frog (they can be found hopping around most of Central America) relies on vocal and visual displays from male frogs to find a suitable mate, but researchers have made a “rather bizarre” discovery that a robotic version of the frog can attract females by hacking into their evolutionary aptitude for filtering out white noise.

CMU Snakebots Infest Nuclear Power Plant

At some point, to be sustainable, research has to make a jump from "do it because it’s cool" to "do it because it’s actually useful and has some sort of practical application that people need and/or will pay for." That’s a big, big jump to make, and many robots don’t successfully cross the gap. We've been hearing for years that Carnegie Mellon’s snakebots are just the thing to undertake inspection tasks in places like nuclear power plants, but now, CMU has put its robots where its papers are, and have stuffed these things into an actual nuclear power reactor. As you can see above, they've even got the snakes operating the controls. Nope, no reason to worry about that, none at all.

DARPA Unveils Atlas DRC Robot

UPDATED 6:32 p.m. More details and photos added.

World meet Atlas. Atlas meet world. With a dash of theatrics, this massive humanoid robot was unveiled today by DARPA at the headquarters of Boston Dynamics, just outside Boston. Atlas was built by Boston Dynamics for the DARPA Robotics Challenge (DRC), whose goal is to advance disaster response robotics. The hope is that Atlas is the first step towards the day when robots, not humans, will be sent to help mitigate major catastrophes, such as the Fukushima nuclear accident.

Boston Dynamics president Robert Playter had Atlas run through a few basic tests for the audience of press and teams participating in the DRC, including a walking demo on a treadmill. As DARPA program manager Gill Pratt explained, in its current form Atlas is "roughly at the competence level of a 1-year-old child." In fact, the demonstrations today were a bit underwhelming (c'mon guys, no push-ups?!) given the complex disaster-response related tasks DARPA has announced for the challenge.

More sophisticated behavior will have to wait until these teams get their Atlases back to their home laboratories, where they will spend many long hours programming the robots to complete the tasks ahead of the competition trials (Pratt estimates that this work will bring Atlas up to about the level of a human 2-year old.) These trials will be held in December at a speedway in Florida, and will be open to the public. The time and location were chosen to minimize the chances of rain, as the Atlas is not yet waterproof.

Atlas itself incorporates hardware from different companies. Boston Dynamics built most of the robot: the torso, arms, legs, and feet. The head is built by Carnegie Robotics, and features a sophisticated range of sensors designed to give the robot 3D awareness of its surroundings, including a laser range finder. Two different pairs of hands will be supplied to the teams, one built by iRobot and the other by Sandia National Labs. Teams will be free to mix and match hands, so a competing Atlas could have a left hand from iRobot, and a right hand from Sandia.

The teams at the unveiling had already met Atlas privately: they were at Boston Dynamics learning how to work with the robot, including the safety issues involved with working with a 150-kilogram robot that can move very fast. Each team will go home with an Atlas, and Boston Dynamics has worked to make the robots as identical as possible. A backup Atlas will be brought to Florida in case of mechanical problems.

Below, photos, specs, and a video of the robot. Check back on Monday, when we'll have more footage of Atlas and interviews with DRC participants.

Specs:

  • Six feet, two inches tall (1.88m)
  • 330 pounds (150kg)
  • On-board real-time control computer
  • On-board hydraulic pump and thermal management
  • Tethered for networking and 480-V three-phase power at 15 kW
  • Two arms, two legs, a torso and a head
  • 28 hydraulically actuated joints
  • Carnegie Robotics sensor head with LIDAR and stereo sensors
  • Two sets of hands, one provided by iRobot and one by Sandia National Labs

The video below, released by DARPA today, has a bunch of old footage, but some new stuff too, although it doesn't appear to show the same version of Atlas that we're seeing in the photo doing anything besides standing there and waving its arms:

Here are photos we took today of the Atlas unveil at Boston Dynamics:
