Dynamic Vision Sensors Enable High-Speed Maneuvers With Robots

We love watching quadrotors pull off amazing high-speed, high-precision acrobatics as much as anyone. But we’re also the first to point out that almost without exception, stuff like this takes place inside a controlled motion-capture environment, and that the quadrotors themselves are blind bots being controlled entirely by a computer somewhere that’s viewing the entire scene at a crazy framerate and from all angles through an expensive camera setup.

It’s going to take something new and innovative for robots to be able to perform high-speed maneuvers outside of a lab. Something like a special kind of camera called a Dynamic Vision Sensor (DVS) that solves the problems that conventional vision systems face when dealing with rapid motion.

U.S. Navy Tests Robot Boat Swarm to Overwhelm Enemies

A fleet of U.S. Navy boats approached an enemy vessel like sharks circling their prey. The scene might not seem so remarkable compared to any of the Navy's usual patrol activities, but in this case, part of an exercise conducted by the U.S. Office of Naval Research (ONR), the boats operated without any direct human control: they acted as a robot boat swarm.

Video Friday: Open Source Humanoid, HelloSpoon, and Drone Versus the Volcano

After some crazy IROS and post-IROS weeks, this week was a relatively calm one. We weren't busy dropping everything and going to talks or expos or workshops or recovering from same.

Except that one on Tuesday.

But anyway, sometimes it's just nice to be able to sit back, relax, and stay up until 5:47 a.m. putting together a good ol' Video Friday for you to enjoy.

Tiny 3D Printed Robots Make Teleoperation Cheap and Simple

Do you have any idea how to operate a robot? If you're reading this blog, odds are that you in fact might. But that makes you a total weirdo, because most people have no idea how to operate a robot. And why should they? If roboticists do their job right, the idea is, no end user should have to learn how to program or how to use a teaching pendant or game controller or whatever. It should all be simple and intuitive and user friendly.

A common approach has been to let users drag robots around to show them a task, which the robot can then remember and execute autonomously. And there's nothing wrong with that, except that it requires the robot to be human safe while you're doing it, and it's harder to jump into the middle of a task to tweak something. Also, if the task requires adaptation (like, trying to grab a randomly moving object), anything pre-programmed gets thrown out the window, and teleoperation is the only way to go.  

RoboPuppet is a way of remotely controlling a robot that makes so much sense, and is so obviously a good idea, that we're honestly not sure why it's taken this long to implement. It's simply an interface where you 3D print a little tiny version of the robot you want to control, add some encoders, and then use the model to puppet the full-size version, which just mimics whatever it is you do. It's adaptable, it's cheap, and it lets even inexperienced users do some remarkable things.

Snake Robot Walks by Turning Its Head and Tail Into Legs

One of the most compelling research areas in robotics is (I think, at least) bio-inspired robotics, which uses the evolutionary optimization of animals to suggest development paths for robots. Animals have had a long, long time to get their designs down, and creating robots that can take advantage of this (either directly or indirectly) provides a bit of a shortcut towards capabilities that are flexible, reliable, and high performance.

It's easy to look at an animal like a snake and be utterly blown away by all of the things that it can do. And lots of people are working very hard to build robots that are capable of doing all of the same things that a snake can do, at least in theory (or simulation). But, it's just as important not to see animals as the absolute pinnacle of what robots should aspire to, because robots are capable of taking advantage of their own designs in ways that biology either hasn't thought of, or physically can't.

Dmitry Grishin: "Robotics Has Too Many Dreamers, Needs More Practical People"

When Dmitry Grishin launched a US $25 million VC firm focusing exclusively on consumer robotics, he encountered a lot of skeptics. They told him that the robots he's interested in were still the stuff of science fiction and it was too early to invest in them. That was two years ago. Today, he says, there's been a "big shift." What changed? "Now everybody believes in robotics!"

Simple 3D Printed Grip Makes Household Robots a Little More Realistic

An absolutely enormous amount of effort is being devoted to teaching mobile manipulator robots how to get things done in environments that are designed for humans. The problem is that unstructured human-friendly environments are not, in general, robot friendly: a daily task that we perform without even thinking about it can be, from the perspective of a robot, somewhere between very difficult and impossible.

A great deal of this aforementioned enormous amount of effort has been focused on making robots as human-like as possible, based on the idea that the more human-like a robot is, the better it'll be able to deal with human environments. So, we're trying to make robots with legs, trying to implement vision systems and databases that let robots look at something and identify what it is, and trying to design anthropomorphic hands that give robots the ability to grasp anything that a human can.

But robots are not really ever going to be like humans (not anytime soon, at least), and it's way easier to just give up on that stuff and instead make some relatively inexpensive and minor modifications to the human environment to make it vastly more friendly to robots. We posted about one example of this last week: using RFID tags to help robots find and identify objects. Here's another one, involving a very simple, very cheap 3D printed adapter that makes it easy for a robot with a simple gripper to pick up and use household tools designed for human hands.

Microsoft Shuts Down Its Robotics Group

In 2007, Bill Gates wrote his influential "A Robot in Every Home" article in Scientific American*, envisioning a future "in which robotic devices will become a nearly ubiquitous part of our day-to-day lives." The article reflected his belief that robotics was going to be hugely important, and Microsoft had to have a major role in it. Two years earlier, Gates had asked one of his top lieutenants, Tandy Trower, also a big believer in robotics, to lead a group with the bold mission of bringing robots into the mainstream

This week, word got out that, as part of its current restructuring, Microsoft decided to shut down its robotics group. (Two sources at Microsoft have since confirmed the news to IEEE Spectrum.) At a moment when excitement about the future of robotics seems to have reached an all-time high (just ask Google and Amazon), Microsoft has given up on robots.

When Drone Delivery Makes Sense

When Amazon first announced its PrimeAir drone delivery service, we were skeptical. And we are still skeptical. Google's announcement of Project Wing did very little to reduce our skepticism about delivery drones operating in urban, densely-populated areas (where people want to receive packages quickly). If anything, it made us more skeptical, since what is apparently Google's best solution to the last 50 feet problem (dangling a package from fishing line) seems, uh, sketchy, at best.

We'd certainly love for Google or Amazon to make urban drone delivery work. We don't think they'll do it anytime soon, but we'd be ecstatic to be proven wrong by some ingenious implementation of technology. In the meantime, however, logistics company DHL has demonstrated one of the specific situations in which drone delivery is actually a good, realistic, achievable thing. Here's why.
