5 degree of freedom robotic Arm

Abstract

A robotic arm is one type of mechanical arm which is similar to a human arm and can do most of the works that a human arm can do. It can do various works which is very risky for a human. A robotic arm is programmable and can do the works through instructions. In today’s world robotic arms are used in industries, rescue purpose and various research works. Considering the facts we thought of designing and making some improvements in robotic arm. Our robotic arm is an arduino controlled six degree freedom robot arm which can move 360 degree and in 6 directions and can do almost all the works of gripping. First of all, the unique part of our robotic arm is, a counter weight is used here to balance the arm while some object is gripped. Secondly, it is able to move to a specific point of its workspace through x, y and z axis values automatically if the points are given. For giving command we are using Bluetooth serial communication system through an Application. This work presents a 6 degree robotic arm with a gripper, controlled with an android application and Arduino MEGA via Bluetooth to carry or load materials. Here, the app searches for the Bluetooth connection, if the Bluetooth device connected with robot is open for connection, then the android app connects with it. Then the app sends command to the Arduino MEGA connected with the robot which is the brain of the robot, this command is fetched by the Arduino MEGA and according to the command it moves the robot forward, backward, left turn, right turn, stop and it expands the gripper to pick a material, squeezes the gripper when a material is picked and it can also move the gripper in left or right direction according to need.
