Tiny robotic cubes self-assemble to duplicate an object that is placed in a heap of the cubes. Possible applications include rapid prototyping and replacing parts or objects. (Source: M. Scott Brauer/MIT)
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.
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
Clean diesel continues to be the fuel of choice for transportation authorities in major U S cities, in spite of competitive options aimed at reducing emissions, according to a nonprofit agency that represents diesel engine and equipment manufacturers.
A panel at this year's Consumer Electronics Show in Las Vegas discussing upcoming FAA regulations for non-military drones brought out many of the issues that concern both industry and federal regulators.
