Harvard researchers, presumably to get into the Halloween spirit of things, have unveiled a horrifying new robotic arm with tentacle fingers capable of grasping extremely delicate objects like houseplants and glassware.The engineers at the university’s John A. Paulson School of Engineering and Applied Sciences (SEAS) used hollow rubber tubing to craft a robot hand featuring what looks like flesh-colored spaghetti that can coil around, or in, its subject before winding back up into a wormy, curly tangle.Instead of optimizing neural networks, sensors, feedback loops, and artificial intelligence systems, however, Harvard’s project leads relied on some relatively basic concepts like inflatable tubing.“The gripper relies on simple inflation to wrap around objects and doesn’t require sensing, planning, or feedback control,” reads Harvard’s recent writeup.Octopus arms don’t inflate, but instead relying on musculature and immensely powerful suction cups with “piston-like” grip abilities, while jellyfish tentacles rely on neurotoxin venom to stun prey ensnare them."
