This project focuses on the design and fabrication of a robotic gripper for handling fragile objects with precision. The system integrates a Bluetooth-controlled pick-and-place robotic arm featuring a servo-driven WPVC (Wood Plastic Composite) arm for lightweight and durable operation. The gripper mechanism is designed to exert controlled force, ensuring safe handling of delicate items such as glassware, electronics, and laboratory equipment. A microcontroller-based system processes user commands transmitted via a Bluetooth module, enabling real-time remote control. The servo motors facilitate precise movement of the arm and gripper, allowing efficient object manipulation. The WPVC structure enhances the arm’s strength while maintaining a lightweight design for improved maneuverability. This robotic system has potential applications in industrial automation, biomedical handling, and warehouse management, reducing human intervention and minimizing damage to fragile goods.
