Bio-inspired robotics has been all over the place. We’ve got robots that walk, run, climb, fly, crawl, and swim. We’ve been kind of missing out on a big domain, though, and that’s animals that dig. You know, like moles. Unlike just about any other sort of robot (or animal), you could have a whole family of moles chillin’ within just a few feet of you (assuming you’re close to the ground, of course) and you’d probably have no idea. And that’s appealing for certain robotic applications:
“One use case is for this robot to drive or be air-dropped to a location close to a target, bury itself to be hidden, perform video surveillance, and send that video back to an operator.”
