Scientists have created a robot “water meter”

Specialists from Harvard University have developed a small robot that can walk both on water and on the bottom.

The device has small pads, which it uses as paddles, floating on the surface of the water. Due to the effect of electro-wetting, the robot moves from a mode of traveling on water to immersion and further movement along the bottom. To avoid short circuits, the robot is covered with a pair of wax.

The device weighs 1.65 g, while it can carry a weight of 1.44 g. The developers gave the robot the name HAMR (Harvard`s Ambulatory Microrobot).
