4-DOF Metal Robot Arm Kit for Raspberry Pi, Bluetooth / WiFi (Robotique)

This 4-degree-of-freedom (4-DOF) robotic arm kit is designed to be controlled by a Raspberry Pi or Jetson Nano board. It includes an aluminium alloy mechanical structure, four metal gear servos (one MG996R and three MG90S), and a servo driver HAT that simplifies wiring via the I2C bus.

Control is easily achieved from a smartphone or tablet using the included Bluetooth or WiFi modules, leveraging the provided Python code examples. The solid base and mechanical gripper allow for precise manipulation of lightweight objects, making it an excellent learning tool for robotics and motor control projects.
