Abstract

This paper proposes a cordless optical power supply for micromachines and mobile microrobot on the air bearing using proposed energy system. The optical mobile microrobot consists of a floating robot with a PLZT element and an air table with air nozzles and electrodes. The PLZT element is a pyroelectric element and works as a transmitter to convert energy from optical energy to electric energy. Illuminating the PLZT with UV rays generates electric energy with electrical voltage high enough to drive the robot by electrostatic force. To solve the friction problem, an air bearing helps reduce friction and the robot to move by slight force. The robot travels floating by levitation of the air bearing. These air systems make it possible for the robot to travel autonomously and to be driven by small force. This paper shows the experimental results of movement and applications of the optical mobile microrobot.
