Wireless power has come a long way from Nikola Tesla’s early ruminations on the matter, and it looks like some researchers from Duke and Georgia Tech are now taking the idea to its logical, robot-powering conclusion. While their setup (thankfully) isn’t yet able to power robots beyond the confines of the Q L-C resonator-equipped table, it does appear to work remarkably well in that limited proof-of-concept, with five bots each equipped with a non-resonant pickup coil able to follow a path around the table, or simply sit still to recharge their batteries. They were even able to power an LED light with the system for good measure. Natually, they eventually hope to expand the system to power larger swarms of robots and do away with the need for batteries altogether. Yeah, that’s a good idea. Head on past the break for a video.

It looks like the Artificial Life XI conference hosted by the University of Southampton was home to a unsettling number of swarm robots this week, including some we’ve seen and some we haven’t. Among the more interesting of the lot are the matchbox-size bots (pictured above) developed by a group of researchers from the host university, which apparently cost just £24 (or $46) each to produce and are able to independently divide up tasks with no central program controlling them. They’re even able to redistribute tasks if some of the robots fail or are removed from the area, which the researchers say makes them ideal for use in far-flung locations and, as the BBC’s video available at the link below shows, they’re also adorable when set to music.

Remember Orb Swarm, that merry band of rolling semi-autonomous spheres? Well, they’ve seen the open-source wizard and came back with a brain. In other words, they’ve gone autonomous, or mostly so as they are now capable of navigating within a pre-defined GPS course. Besides navigation, these orbs feature an embedded processor, accelerometer and ZigBee wireless communication all of which allow the rolling spheres to “flock , flirt, dance and interact,” say their creators. They’re set for release en masse onto the Burning Man playa at the end of this month where they’re sure to punish chemically-influenced revelers with a sense of panic suitable to the uprising. Check the video after the break for a taste if participating in pagan festivals celebrating experimental living is a bit beyond your sense of sheltered sensibility.
