Stage-wise Development of a Remote Controlled Robotic Arm

Abstract

This paper represents the stage-wise development of trainable remotely controlled robotic arm based on servo motors. The robot is expected to perform primary pick and place operations and repeat the recorded actions with error corrections. The arm has four degrees of freedom. The robotic arm is mounted on a base that allows it to traverse between different coordinates. Arduino Mega 2560 is used for controlling functionalities of the robot. The robot was developed in four stages. In the first stage, the robot was controlled with the help of potentiometer. In the second stage of development, remote functionality was added. This functionality was achieved using Bluetooth module. The third stage of development included usage of the real-time remote control over the internet. The robot was controlled using an android application for the stages mentioned above. In the fourth stage, a Unity-3D model was integrated to realize the real-time visual simulation of the robot.
