Universal Robots UR3 Arm Is Small and Nimble, Helps to Build Copies of Itself

This Danish family is growing. Universal Robots, based in Odense, Denmark, is announcing today a new addition to its line of industrial robotic arms. The new arrival is called UR3, and it’s smaller than the company’s earlier models, UR5 and UR10. Compared to its older siblings, the little UR3 looks light and nimble—and even “cute,” as one observer described it.

MIT's DragonBot Evolving to Better Teach Kids

MIT introduced Kombusto, their dragon robot designed to teach stuff to preschoolers, back in 2011. Since then, the Personal Robots Group has been doing a substantial amount of research and experimentation to figure out how best to utilize the robot to productively interact with children. We have some updates on how it’s been going, along with a look at the brand new robot that MIT is developing to work with kids for months at a time.

Video Friday: Robots Push It to the Limit, Designing a Drone, and Zoomer Kitty

Next week promises to be an amazing one for robotics. We’re getting word that there will be not one, not two, but three new robot announcements. We’ll have all the details for you here on the blog, of course. But today is Friday, and we know why you’re here. Let’s get to it.

Universal Robots Wants to Conquer the Universe (of Robotic Arms)

Last month, Enrico Krog Iversen, the CEO of Universal Robots, showed up at the IEEE Spectrum office in New York City with a large cardboard box. Inside was a shiny, sleek gray-and-blue robotic arm, and before I could hand him my business card, Iversen and one of his engineers had set up the robot on the conference room table.

What Might Happen If an Airliner Hit a Small Drone?

In January, I wrote about a study from the failure-analysis company Exponent that examined the threat very small drones—ones of just a kilogram or two—could pose to aircraft if there were a collision. That study did so by looking at the kinds of damage done by birds of similar mass.

Some of the people who read that post responded that it glossed over the differences in composition between drones and birds, suggesting that drones, with their many metal parts and lithium-ion batteries, would be inherently more damaging. That seemed a fair critique to me, so I contacted George Morse, an expert on foreign-object damage to aircraft, to get his opinion.

Morse’s company, Failure Analysis Service Technology, based in Prescott, Ariz., specializes in the analysis of aviation mishaps, foreign-object damage in particular. Morse himself has done more than 4000 engine investigations, most the result of ingestion of nuts or bolts or other runway detritus rather than birds. So he’s probably in as good a position as anyone to suggest what the results might be if an aircraft were to collide with a small drone weighing a kilogram or two.

AI Researchers Propose a Machine Vision Turing Test

Computers are getting better each year at AI-style tasks, especially those involving vision—identifying a face, say, or telling if a picture contains a certain object. In fact, their progress has been so significant that some researchers now believe the standardized tests used to evaluate these programs have become too easy to pass, and therefore need to be made more demanding.

DARPA Robotics Challenge Finals Will Have 25 Teams, and a Surprise Task

The DARPA Robotics Challenge (DRC) just got bigger, more awesome, and more international. DARPA has just announced that 14 new teams from seven different countries have qualified to participate in the DRC Finals. These 14 teams join the 11 teams previously qualified during the DRC Trials.

This means a total of 25 teams will compete in what is possibly the most anticipated robotics event ever. Twenty five robots are a lot of robots. They will converge to the simulated disaster zone that DARPA will set up in Pomona, Calif., where the DRC Finals will take place in June.

In a call with reporters this afternoon, Gill Pratt, program manager for the DRC, said the tasks for the final challenge will be similar to the ones we saw at the trials. But this time the tasks will be “put together in a single mission” that teams have one hour to complete.

The robots will start in a vehicle, drive to a simulated disaster building, and then they’ll have to open doors, walk on rubble, and use tools. Finally they’ll have to climb a flight of stairs. But one more thing, Pratt said: there will be a surprise task waiting for the robots at the end.

The Heaphy Project: Crowdsourced Robot Servants and the Willow Garage Spin-off That Never Was

Willow Garage, the now-disbanded Silicon Valley robotics incubator, unleashed some of the most impactful robot technologies of the past half-decade. Today, this formidable legacy lives on, in great part, through a host of Willow spin-offs that remain at the forefront of robotics. This article is not about them.

It’s about a Willow Garage project that was, at one point, on the verge of being spun out of the incubator, but is now all but forgotten. The project, called Heaphy, recognized that robots were still too limited in what they could do autonomously, and that instead of improving artificial intelligence, an alternative would be relying on more human intelligence.

Heaphy aimed to recruit people online and train them to operate Willow’s powerful PR2 robots to carry out everyday tasks like serving drinks and collecting trash. The remote operators would be paid for their work and could be anywhere in the world, using only a web browser to control the robots. Thus the idea of crowdsourced telerobotic labor was born.

To be sure, the notion of a stranger halfway around the world commanding a robot servant and doing your chores for you sounds like something straight out of a sci-fi movie. But as it happened, Heaphy demonstrated that that concept could potentially work in the real world.
