A new agile robot designed to move quickly through the labyrinths

Engineers at the University of California, Berkeley have analyzed what helps insects to run around

walls and walk upside down on the ceiling.To create a new robot, scientists used the principle of electrostatic adhesion (adhesion to a surface). He is fast enough, agile, can cross any terrain.

The robot is made of thin laminated material,which bends and contracts when an electrical voltage is applied. In a 2019 article, the research team demonstrated that this simple design can be used to create a robot the size of a cockroach that can move across a flat surface at a speed of 2 km / h. This speed seems small, but it is comparable to a speed of 33 m / s for a person. This is a record for robots the size of an insect.

In a new study, scientists added two electrostatic foot pads to the robot's design. Applying tension to any of them increases the "grip" of the limb to the surface.

The new robot will come in handy in search and rescue operations or identifying potential gas leaks. Tests have shown that he is able to navigate the Lego maze in seconds.

In addition to the device, which is controlled by a small electrical wire, the scientists have created an autonomous robot. He works 19 minutes at a distance of up to 31 meters.
