The SainSmart 4-Axis Robotic Arm is designed to be both an amazing toy and an engaging teaching tool.  Modeled to simulate a full-scale palletizing robotic arm, the SainSmart Arm comes with a basic code to test and also allows users to customize their own procedures.  With a range of up to 300 mm (nearly 12”) and 4 axes of freedom, the 3 copper-gear servos allow for incredible flexibility in movement, and can even be precisely controlled using the 9-axis accelerometer gyro controller.  The arm can exactly mimic your own movement!  Unleash that childlike creativity and experience the wonder of robotics today!

Motion Translation

The remote controller and its integrated accelerometer gyroscopes accurately translate the motion of your hand into the movement of the robotic arm.  You’re in full control!

Precise Control

Arm movement is produced by responsive, precision servos.  Motion is snappy and the delay is minimal!


The Arduino-compatible microprocessor is fully customizable.  Use the basic code provided to start, and then create your own custom programs!
