Design and Implementation of Robotic Arm Pick-and-place Using PIC Microcontroller

Abstract

A robotic arm is constructed with electronic devices and mechanical parts and it is based on the PIC microcontroller. The robotic arm is designed to pick a ball coming into the predetermined place. After that the arm will place the ball to another predetermined place. The arm can move either to the right or to the left by the control of the operator. The number of balls picked by the arm are counted and displayed on the 7-segment LED display. Two digits of 7-segment displays are used in this system. The number of balls to be picked up by the arm are limited to 10 by the program instruction. An Pic Basic Pro language is used to control the operation of the robotic arm. Opto-isolators and switches are applied to detect the status of the arm and incoming ball.
