Too Long; Didn't Read
Engineers from the University of California, Berkeley, used the principle of the footpads, which is known as electrostatic adhesion, to come up with an insect-sized robot that can move like insects. The robot is created using material that contracts easily with the application of electric current. This is a unique feature that is included in the robot. The insect robot can slither across a distance with a speed of about 1.5 miles/hour. This was determined as a speed similar to that of cockroaches and as an insect robot.
