There are robots, and then HAMR-Jr (Harvard Ambulatory MicroRobot), a cockroach-inspired quadrupedal robot that might scurry around homes of the future. It’s powered by piezoelectric actuators that enable it to travel nearly 30cm per second, at a gait frequency of 200 hertz. For comparison, the highest known frequency of a synchronized insect muscle contractions is 224 Hz, which happens in the tymbal muscles of the Australian cicada.

HAMR-Jr is capable of crawling, jumping, and moving sideways like a crab with payloads of up to 320 mg. What are some practical applications? Robotic surgery and rescue missions, with the latter focusing on crawling into rubble to find survivors.

With HAMR-Jr, we can cycle the legs at the rate of over 200 Hz, which is unprecedented for terrestrial biological systems, and we did not have a priori notion about the locomotion dynamics at these high stride frequencies,” said Kaushik Jayaram, University of Colorado Boulder.
