Overview

A 4.5 cm robotic cockroach from Robert Wood's lab at Harvard, built with the pop-up laminate (PC-MEMS) process also used for the RoboBee. Piezoelectric actuators drive each leg at up to 45 Hz, and it can run at over 10 body lengths per second while carrying more than twice its weight. Variants climb vertical and inverted surfaces with electroadhesive feet (HAMR-E, 2019), walk on the bottom of a tank and swim on the surface (2018), and shrink to penny size (HAMR-Jr, 2020). Most versions need a tether for power and control.
