6 DOF Robotic Arm Control using Arduino Uno and Bluetooth Module

Robotic arm manipulators are used in many industrial and commercial applications. The arm that we have designed here has 6 DOF(Degrees of freedom) which gives it ample movement in 6 different axes. We have used 6 servo motors for accurate and quick arm movement. By interfacing it using the Arduino Uno it was fairly easy to program the 6 motors and run them simultaneously. The entire arm is controlled by a smartphone using the HC-05 Bluetooth module, thus making the user interface fairly simple. This robotic arm performs pick and place operations with high accuracy, low power requirements, and minimum operating difficulty.
