Scientists have built a robotic cockroach that can walk on land, swim on the surface of water, and explore grounds underwater for as long as necessary. The Ambulatory Microrobot, known as HAMR, uses multifunctional foot pads that rely on surface tension when it needs to swim. However, it can also apply a voltage to break the water surface when it needs to sink.
