Design and Implementation of a Bluetooth-Controlled Robotic Arm for Efficient Pick-and-Place Operations

The advancement in Robotics and Automation, particularly in IoT, has led to the development of Bluetooth-operated robotic arms. These arms perform tasks like pick and place, reducing human fatigue and error. Two control strategies, force, and motion control, enable precise operations. By using smartphones with Bluetooth connectivity, users can control the arm remotely. The Bluetooth module, like HC05, facilitates this connection. Such arms can handle hazardous materials or tasks in inaccessible areas. These arms offer flexibility and can be reprogrammed for various tasks. Designed using Arduino Uno and four servo motors, they are controlled via a mobile app, ensuring user-friendly operation. The system, modeled using CAD software and 3D printing, enhances safety and efficiency in industrial setups. It enables remote control and precise movements for tasks like handling munitions.
