Overview

Equip your micro:bit 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 board, metal mechanical arm structure, and 4x metal gear servos. When used with the micro:bit, it is easy to control the arm by smart phone through Bluetooth connection.

The Servo Driver

Adopts Servo Driver for micro:bit:

• micro:bit edge connector, directly pluggable
• 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 servo such as SG90, MG90S, MG996R, etc.
• Reserved I2C control pins, allows to work with other control boards
• Comes with development resources and manual (micro:bit graphical examples like Bluetooth/2.4G wir eless 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 (1x MG996R, 3x MG90S), large torque force, smooth moving
