Insect-sized robot powered by tiny explosions can crawl, leap and carry a load 22 times its own weight.
Researchers used four actuators to drive the robot’s feet.
A stream of methane and oxygen is fed into each foot and sparked with electricity from a battery.
The resulting reaction between the gases to form water and carbon dioxide releases energy as a small explosion.
