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.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
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.
