An Insect-Scale Self-Sufficient Rolling Microrobot [PDF]

open access: yesIEEE Robotics and Automation Letters, 2020
We design an insect-sized rolling microrobot driven by continuously rotating wheels. It measures 18mm$\times$8mm$\times$8mm. There are 2 versions of the robot - a 96mg laser-powered one and a 130mg supercapacitor powered one. The robot can move at 27mm/s (1.5 body lengths per second) with wheels rotating at 300$^\circ$/s, while consuming an average ...
