Swarming And Hopping Planetary Robots
An anonymous reader writes "Recently Dr. Penelope Boston (U. New Mexico) and Dr. Steven Dubowsky (MIT) discussed their NASA advances to develop 'hopping microbots' capable of exploring hazardous terrain, including underground caves and planetary extremes. 'We came up with the idea of many, many, tiny little spheres, about the size of tennis balls (slide show), that essentially hop, almost like Mexican jumping beans. They store up muscle energy, so to speak, and then they boink themselves off in various directions. That's how they move...They behave as a swarm [of 1000s]. They relate to each other using very simple rules, but that produces a great deal of flexibility in their collective behavior that enables them to meet the demands of unpredictable and hazardous terrain.' Test prototypes available in March will initially explore terrestrial lava tubes."
Isn't the main issue how to power the balls? They'll need energy to hop around, make measurements and communicate.
I don't think the ad hoc wireless network aspect of things is likely to be the hard part: if people can solve the power problems, Siemens, Sony, Panasonic, Toshiba and Philips will likely take care of the network/software part in the course of solving our more earthly problems.
E.g. a security system built of these would seem to have wide appeal.

This reminds me of DARPA's self-healing minefield, where mines communicate with each other and 'hop' to fill any gaps in their net. DARPA's page here: http://www.darpa.mil/ato/programs/SHM/
