Robotic Arm

This project is a description of the design and implementation of a smart phone controlled, programmable robotic arm using an Arduino microcontroller and Bluetooth communication. The robotic arm is powered by servo motors, which are controlled by a HC-05 Bluetooth module, and can be controlled wirelessly through a smart phone application. The main aim of this system is to enable the users to control the robotic arm remotely for use in automation, education and prototyping. The system uses the Arduino to provide precise control of the arm’s movement, with the smart phone acting as the user interface to send real time commands. The control app on the smart phone can be used to manually operate the robotic arm or to program it to perform certain sequences of movements. These movements are then translated into servo actions using PWM signals to control the arm’s joints. This project shows the effectiveness of the application of wireless communication, embedded systems, and robotics, with a low cost and high versatility for tasks such as object manipulation and demonstration.
