4-DOF Metal Robot Arm Kit for Raspberry Pi, Bluetooth / WiFi Remote Control


Equip your Raspberry Pi with this 4-DOF metal robot arm, and get started to explore the world of artificial intelligent robotic.

This starter robotic arm kit includes: servo driver HAT, metal mechanical arm structure, and 4x metal gear servos. When used with the Raspberry Pi, it is easy to control the arm by smart phone through Bluetooth or WiFi connection.

The Servo Driver

Adopts Servo Driver HAT:

  • Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano
  • I2C controlled, using only 2 pins
  • Up to 16-Channel servo/PWM outputs, 12-bit resolution for each channel (4096 scales)
  • Integrates 5V regulator, up to 3A output current, can be powered from battery through VIN terminal
  • Standard servo interface, supports common used servos
  • Reserved I2C control pins, allows to work with other control boards
  • Comes with development resources and manual (examples in python like Bluetooth/WiFi remote control)

The Robot Arm Structure

  • 4-DOF, large solid base, metal mechanical grasper
  • Full aluminium alloy body, sandblasting oxidation surface, strong & durable
  • Clever mechanical structure and mounting design, agile to control, easy to build
  • Fitted with 4x metal gear servos, large torque force, smooth moving
