Abstract

Hazardous work environments such as in radioactive site and space station give high risk to the worker safety. This risk can be reduced by using robot technology that able to take over the human works. For industry purpose, the robot that needs to be developed must have high performance especially in accuracy, stability and consistency. However, the current industrial robot is not flexible which can’t be used for the different tasks. So, multi-purpose robot is proposed to be developed in this project. The objective of this project is to design and developed a robot hand with wireless communication. The robotic hand communicates with human in master-slave manner. This manner will help the robot perform for different task without need to reprogram it. In this project, Xbee wireless module is used because it provides a short-range communication channel. The master part is operated by using a data glove that mounted with sensors to measure the flexion of the fingers, which can wear by a human operator. The movement of human fingers will transferred to the slave robotic hand that will mimic the finger movement. The robotic hand prototype has designed by using SolidWorks software. It designed with 5 fingers and has dimensions similar to human hand. Each robotic finger is powered by servo motor and drive by using wire as the actuator. Wire is used to make a link between finger and motor in order to control the finger flexion by rotating the motor. To control the robot hand system, Atmega328 microcontroller is used to for data glove system and also controls the actuation system for robot hand motion. In master part, a microcontroller is used to process the input signal that it measure from the sensor and transmit the signal to the slave robot hand. While in robot hand, a microcontroller is used to process the receive signal and produce output to perform motor operation.
