CLASH Robot Can Climb Vertically Like an Insect
“UC Berkeley has a long history of developing innovative legged robots: There was ROACH, there was BOLT, there was DASH. DASH, a cockroach-Inspired design, was a very simple, very fast hexapedal robot that could scuttle along the ground at 15 body lengths per second.
Now meet the latest addition to this family of robot bugs: CLASH, pictured above, is a vertically-enabled successor to DASH, and it’s designed to zip up vertical or near-vertical cloth surfaces with the aid of tiny little spiny toes. It’s sort of like what you’d get if you put DASH and SpinyBot together in a dark room along with a 3D printer and some Barry Manilow (or whatever it is robots are listening to these days).
For a vertical climbing robot, CLASH is surprisingly quick. It may actually be one of the quickest climbing robots in existence, able to move upwards at 24 centimeters per second, which is really quite a lot faster than it sounds.
Part of the reason that CLASH can scramble around so fast is that it’s small and lightweight with a simple, but clever, design. CLASH is 10 centimeters long and weighs only 15 grams. The back-and-forth climbing motion of four legs (the back two are passive) is entirely driven by one single motor that gives CLASH a gait frequency of a brisk 34 strides per second.”
