Catch-And-Release Method For Microbots
When using a tiny robot to assemble miniature devices such as microelectromechanical systems, surface electrostatic forces come into play. For instance, attractive forces allow a robot’s little gripper to snag a microscopic component and move it into a desired position. But the adhesion can be problematic when the robot is supposed to let go of the component. Researchers in Besançon, France, have now found a simple way to gain better control over these . . .
