The HKD Economical 4-DOF Robotic Gripper Arm Kit is a lightweight and affordable solution for robotics projects and STEM learning. Built from precision laser-cut wood parts, this robotic arm is both sturdy and lightweight, weighing only about 230g.
Each joint is powered by an SG90 or MG90S servo motor, providing smooth movement and flexibility across 4 degrees of freedom (4-DOF). The kit is designed to be compatible with Arduino, Raspberry Pi, and other microcontrollers, making it perfect for hobbyists, students, and educators looking to explore robotic control systems.
Note: This kit does not include a control board. Customers will need to provide their own controller (Arduino, Raspberry Pi, etc.).
