Design and construction of system to control the movement of the robot arm

Abstract

The objective of this project was to study on the design and construction of a system to control the movement of the robot arm from remotely via wirelessly glove using flex sensors and the variable resistor. The designed and constructed of the project composed of 5 main parts : 1) The detector consists of a control unit with Flex Sensors and a Position Sensors (variable resistor), 2) the signal conditioner part includes Voltage Divider circuit and voltage differential amplifier circuit, 3) the signal processing part using microcontroller Arduino Mega 2560 with C-language program, 4) the signal transmitter and receiver part using Xbee series 2 module (Zigbee Wireless Standard) and 5) robot arms designed and construction with Cartia program and 3-D printer. The results of functional testing of the project showed that this system can control the movement of the fingers, wrist, elbow and shoulders complying with the objectives of the project.
