Programmable Arduino Robotic Arm Smartphone Control

Download Project Document/Synopsis

Robotic arms are now used in a wide variety of applications, from industrial automation to automatic burger making arms. The key component of any automatic robotic arm is its ability to learn motions or the ability of arms to be programmable by the user. This usually involves programming the arm each time with set of instructions to be followed.

Well we hereby develop a smartphone controlled programmable robotic arm that can be easily programmed via a smartphone to perform any automated repetitive tasks as desired by user. The arm makes use of 6 servo motors controlled by an arduino Uno to achieve the task.
This Arduino powered arm provides the following advantages:

6 DOF arm for 360° Movements
Programmable Arm as per user automation process
Smartphone controlled system with no added programming hardware needed
Easy to control movements with sliders instead of complicated programming

The 6 Dof arm makes use of 6 servo motors controlled by an arduino Uno controller. The controller is interfaced with a Bluetooth receiver that is used to receive commands via the android app. The arm gripper is made up of 2 claws which are also controlled by a servo motor. The gripper angle is also be rotated by another servo for a 180° orientation to pick up and place objects of any orientation.

The android app consists of an easy to use gui with sliders used to transmit servo movement commands. The user can record steps and save each step through the app.

The programming commands transmitted by app are received by the Bluetooth receiver and passed over to arduino controller. The controller records movement commands of each servo step and saves it. The controller can now repeat the set of steps so as to execute the entire movement command with desired coordination with each servo to achieve the program repetitively.
Thus the system provides a smart mechanism to use a 360° programmable robotic arm with smartphone controlled system.
