Construction of Wireless Piezoelectric Micro Robots with Arduino Control Module

Abstract

Based on our previous researches, wireless piezoelectric micro robots integrated with the Arduino control module have been presented. The construction of the robot is included with the frame body, the piezoelectric beams, the miniaturized voltage amplifierpiezo driver, the Bluetooth module, the micro sensor and the Arduino controller (Arduino nano or Rfduion-Simblee). The volume of the robots can be shrunk into a size of several dozen cubic centimeters. In contrast to general mobile micro robots, the actuating mechanism of the robot is piezoelectric bimorph beam(s) and the driving principle is the traveling-wave as drive source to actuate the robot. The robots can move back and forth and rotates counter clockwise or clockwise, respectively. They can be wirelessly controlled by the Bluetooth module of HC06 or Rfduino-Simblee. For further application, the robots can be integrated with micro sensors to interact with the environment parameters. In this paper the HC-SR04 ultrasonic sensor and photo sensitive resistor are used for demonstration.
