Hasta La Gadget!

Can’t unwind without the aid of open spaces? Skippy the robot might be able to help you out. The aptly named bot lets you remotely skip stones across an Idaho pond using a simple web interface. After waiting for your turn in a virtual queue, the machine lets you adjust its aim, tweak the amount of force behind the pitch and dispatch a rock. Best of all, your stone jumping exploits are automatically recorded, letting you show off your skipping prowess. Devised as a way to raise awareness for Idaho’s Sun Valley resort area during the summer months, the mechanical projectile chucker seems to be arduino-powered, and operates only during daytime hours. Check out the source to start pelting pebbles, or venture past the break for two short videos of the contraption in action.

Scientists from the University of Arizona have developed the most accurate robotic replication of human legs that take it beyond just human-like movement. The robot, which can walk just like a human, will be able to help them understand how human babies start learning how to walk and how to better treat spinal related injuries.

The robot uses motors that push and pull on kevlar straps, which represent human leg muscles, allowing it to achieve nearly identical human-like movement. Even more amazing than that is the fact that the robot also has a computerized version of the central pattern generator (CPG), which is what humans use to collect information from their body. The CPG is what allows people to walk without thinking about walking, adjust strain on leg muscles, evaluate load patterns from each foot, and so on.

Additional enhancements to the robot are expected to be made in the future, including visual and tactile sensors as well as the ability to pick itself up again after falling down. And even though there have been robots that have previously replicated human movement before, this is the first one that has been able to accurately replicate the underlying human control mechanisms that actually drive the movement.

Researchers at DARPA are working on robots with hugely increased power efficiency, chasing human-style actuation that would prolong battery life and significantly extend robotic runtime. The M3 Actuation program has set an ambitious 2,000-percent increase in power-transmission and application in robots, improving performance not only in areas like search & rescue and drones, but advanced prosthetic limbs and other fields.

It’s not just making more efficient motors. According to DARPA, successful teams might look at a combination of “low-loss power modulation, variable recruitment of parallel transducer elements, high-bandwidth variable impedance matching, adaptive inertial and gravitational load cancellation, and high-efficiency power transmission between joints.”

There will be two different tracks of work ongoing simultaneously, one with a more practical focus and another that will look more at the science and engineering behind actuation. The eye-candy is likely to show up in Track 1, where teams will be required to actually outfit physical robotics systems with their creations:

“Track 1 asks performer teams to develop and demonstrate high-efficiency actuation technology that will allow robots similar to the DARPA Robotics Challenge (DRC) Government Furnished Equipment (GFE) platform to have twenty times longer endurance than the DRC GFE when running on untethered battery power (currently only 10-20 minutes). Using Government Furnished Information about the GFE, M3 Actuation performers will have to build a robot that incorporates the new actuation technology” DARPA

DARPA is now inviting proposals from teams that believe they can put together something along those lines. The Maximum Mobility and Manipulation robotics program will culminate in a live competition in December 2013, followed by a second live final in December 2014.

The Phoenix Frankenprogram to harvest the corpses of expired satellites and cobble together new ones seemed like one of DARPA’s more daft ideas, but this one has actually kicked off its first phase of development. The plan is to first launch a service craft — replete with robotic arms and enough processing horsepower to work independently if needed — followed by the tiny base-unit skeleton satlets. The service mothership would dip into an orbital area called the “graveyard”, grabbing pre-chosen cadavers and picking off usable parts, especially valuable antenna arrays, with its robo-limbs. Those parts would be jury-rigged to the bare-bones units, creating usable Pentagon satellites and saving the $10,000 per pound launch cost. So far, a $2.5 million contract to develop the needed technology has been put in place, and bids for the no-frills satlets went out last week. Plenty of dirty work is still needed, so check the video after the break to see if the overly-elaborate plan can un-moot $300 billion of orbiting cold metal.
