Description: The footage shows a robot of 300x300x70 micrometers pushing a ball (gold microdisk) from one goal to the other on an competition field.
The robot features a novel actuation principle of magnetically induced mechanical oscillation (impact drive actuator) and phase locked electrostatic clamping. The robot is moved by the combination of oscillating magnetic fields which induce mechanic oscillation in one of the masses (due to mutual attraction, please see animations on linked pages) and phase-shifted oscillating electrostatic clamping. The phase shift of the clamping controls whether the robot goes backwards or forward: either the robot is held in place while the oscillating mass swings back (thus robot going forward) or when it swings forward (robot going backward). also, the same magnetic field controls the orientation, since the robot has those two nickel masses with an overall elongated shape which naturally aligns with the field.
The robots can turn left and right, go forward and backwards at controllable speeds, and turn in place. The robot can currently go at speeds of 1.25cm/second. But that is just an arbitrary speed set by the current system and the current prototypes. We think it can go significantly faster and still be controlled.
