Robotic Arm with Finger Movement

Abstract

Robotic arm is an electro-mechanical system with functions similar to that of human arm. The proposed robotic arm is intelligent in the sense that it senses the movement of human arm with the help of the sensors attached to the hand and then move in accordance with it. Many exoskeletal robotic arms have been developed for teleoperation having force reflection. They can measure operator’s arm motion and apply reactive force to the operator as well [1]. The movement of robotic arm is basically due to the two main components which are servomotor along with microcontroller. Since, this design includes servomotor for the movement of robotic arm, this will give very precise movements. Movement of servomotor is based on width of the rectangular pulse generated by the combined working of the monostable and astable multivibrator. As the pulse width changes servomotor detects the changes in it and then moves accordingly.
