Once we consider greedy robots, we consider manipulators of some type on the ends of arms of some type. Due to course we do—that’s how (most of us) are constructed, and that’s the mindset with which we have now consequently optimized the world round us. However one of many nice issues about robots is that they don’t must be constrained by our constraints, and at ICRA@40 in Rotterdam this week, we noticed a novel new Thing: a robotic hand that may detach from its arm after which crawl round to know objects that will be in any other case out of attain, designed by roboticists from EPFL in Switzerland.
Essentially, robotic arms and crawling robots share plenty of similarities, together with a physique together with some wiggly bits that stick out and do stuff. However most robotic arms are designed to know somewhat than crawl, and so far as I’m conscious, no robotic arms have been designed to do each of these issues on the similar time. Since each capabilities are essential, you don’t essentially need to stick to a standard grasping-focused hand design. The researchers employed a genetic algorithm and simulation to check a bunch of various configurations in an effort to optimize for the power to carry issues and to maneuver.
You’ll discover that the fingers bend backwards in addition to forwards, which successfully doubles the methods wherein the hand (or, “Handcrawler”) can grasp objects. And it’s a bit bit arduous to inform from the video, however the Handcrawler attaches to the wrist utilizing magnets for alignment together with a screw that extends to lock the hand into place.

The entire system is managed manually within the video, however lead writer Xiao Gao tells us that they have already got an autonomous model (with exterior localization) working within the lab. In actual fact, they’ve managed to run a whole greedy sequence autonomously, with the Handcrawler detaching from the arm, crawling to a location the arm can’t attain, choosing up an object, after which returning and reattaching itself to the arm once more.
