A UC Berkeley researcher has fabricated a solar powered microrobot prototype that can jump nearly 30 times its height using the world's smallest rubber band. The simple microbot is just 7 millimeters long and can jump 200 millimeters high. The rubber band that enables the jumping is cut in a circular strip measuring just 9 microns thick and 2 millimeters long out of a thin sheet of silicone using an infrared laser...Read more about the research here and here.
