Micro-Bristle-Bots Powered by Vibrations

Micro-Bristle-Bots Powered by Vibrations
Tiny 3D-printed robots that move by harnessing vibration could work together to accomplish complex tasks—including repairs to the human body.

Developed by a team from Georgia Tech, the micro-bristle-bots were 3D printed using two-photon polymerization lithography, and are equipped with a set of bristle-like legs. The action of the legs is controlled by adjusting vibration frequencies, which can be transmitted to the bot with a ‘shake table,’ ultrasound or sonar, or an acoustic speaker. The team believes the bristle-bots could have eventual applications in traveling tiny spaces, transporting temporary environmental sensors, or even helping heal injuries in the body.
