We’ve seen robots take to the air, dive beneath the waves and perform all sorts of maneuvers on land. Now, researchers at UC Santa Barbara and Georgia Institute of Technology are exploring a new frontier: the ground beneath our feet. Taking their cues from plants and animals that have evolved to navigate subterranean spaces, they’ve developed a fast, controllable soft robot that can burrow through sand. The technology not only enables new applications for fast, precise and minimally invasive movement underground, but also lays mechanical foundations for new types of robots.
“The biggest challenges with moving through the ground are simply the forces involved,” said Nicholas Naclerio, a graduate student researcher in the lab of UC Santa Barbara mechanical engineering professor Elliot Hawkes and lead author of a paper on the cover of the journal Science Robotics. Whereas air and water offer little resistance to objects moving through t

Simple Robots, Smart Algorithms: Meet the BOBbots
Anyone with children knows that while controlling one child can be hard, controlling many at once can be nearly impossible. Getting swarms of robots to work collectively can be equally challenging, unless researchers carefully choreograph their interactions like planes in formation using increasingly sophisticated components and algorithms. But what can be reliably accomplished when the robots on hand are simple, inconsistent, and lack sophisticated programming for coordinated behavior?
A team of researchers led by Dana Randall, ADVANCE Professor of Computing and Daniel Goldman, Dunn Family Professor of Physics, sought to show that even the simplest of robots can still accomplish tasks well beyond the capabilities of one, or even a few, of them. The goal of accomplishing these tasks with what the team dubbed dumb robots (essentially mobile granular particles)
