Robot bugs, developed by a group of researchers at the University of California, can climb walls and move on ceilings. Thanks to a special thin-layer material that bends when alternating current is applied, the robot bug can move quickly and limberly. Thanks to the electrostatic force between the insect's leg and the surface, the robot's tight adhesion to the surface and its ability to rotate around the leg is ensured. It is stated that this developed small robot can be used in dangerous situations such as search and rescue operations or gas leaks.
