## Summary

ETH Zurich published a blog post on October 22 showcasing a biohybrid microrobot about 1.5 centimeters long, made from mouse skeletal muscle cells and a hydrogel scaffold, that can jump, run, swim, and grasp. The team used an algorithm to simultaneously optimize muscle tissue distribution, volume, and the hydrogel scaffold's shape and mechanical properties, achieving motion amplitudes up to 11 times greater than previous systems with similar muscle mass; the walking version reaches a speed of 6.2 millimeters per second, about 0.4 body lengths per second, which the study says is the highest speed reported to date for a walking biohybrid robot.
