After popping out of a special 3D printer, this remote-controlled specimen activates by laser.
This may be the tiniest robot you’ve ever seen.
Shaped like a peekytoe crab, it’s a half-millimeter across and it can crawl, jump, bend, and twist through tiny apertures. The edge of a coin provides an ample landscape for its crabby walk.
As the smallest remote-controlled walking robot ever created, this prototype micro robot brings the field of robotics one step closer to performing practical tasks within tight spaces, such as repairing small machines.
“Our technology enables a variety of controlled motion modalities and can walk with an average speed of half its body length per second,” says the project’s lead theoretical researcher, Yonggang Huang, in a news release. “This is very challenging to achieve at such small scales for terrestrial robots.”
