I interviewed Kyle Gilpin at ICRA 2010 about his work with the robot pebble, which is the "grain" in the "smart sand" This interview is part of the Flexible Elements podcast series, focusing on Self-reconfiguring modular robotics, at IT Conversations
Interesting idea which reminds me of the natural evolution of primitive single cell organisms into more complex mult-cellular organisms (which evolve into even higher and higher complex organisms as time goes on). Each robotic pebble reminds me of a cell, so I'm wonder if more complex robotic mechanisms can be made from larger and larger groups of multi-pebbled clusters.
Greg, I had a similar initial idea about the analogy with cellular structures. Reading the wiki page and other background info in depth made it clear that there are current limits to the number of neighbor cubes that can attach. At least some of that limitation seems to be due to hardware, such as space limitations causing magnets on 4 not 6 sides, and, as we state in the article, the current upper limit is 80 neighbors per cube. Once they move to the smaller 1mm size on a wafer, that number is expected to rise to 100s or 1000s.
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
Design News and Digi-Key presents: Creating & Testing Your First RTOS Application Using MQX, a crash course that will look at defining a project, selecting a target processor, blocking code, defining tasks, completing code, and debugging.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
