Researchers at Harvard University's Paulson School of Engineering and Applied Sciences (SEAS) and Wyss Institute for Biologically Inspired Engineering have created a scaled-down version of a cockroach-inspired microrobot.

The highly dexterous HAMR-JR is a half-scale iteration of the Harvard Ambulatory Microrobot (HAMR), which demonstrates that the pop-up manufacturing process for its larger predecessors works at multiple scales.

The process involves etching components into a two-dimensional (2D) sheet that pop out in the robot's three-dimensional structure, and maintains HAMR's functionalities by shrinking its 2D sheet design, as well as actuators and onboard circuitry.

Since scaling down changes certain dynamic principles, the researchers developed a model to predict locomotion metrics that can be used to design a system with the required specifications.

SEAS' Robert Wood said, "This new robot demonstrates that we have a good grasp on the theoretical and practical aspects of scaling down complex robots using our folding-based assembly approach."
