DAMIAO Technology

A Shenzhen joint-motor maker whose DM-J4310 is a common small joint in student and open-source robots.

Shenzhen DAMIAO Technology Co., Ltd. was founded in 2019 and is based at the Nanshan University Town entrepreneurship park in Shenzhen. It makes integrated joint motors, hub motors, and gimbal motors for robots, along with the DM40-DM100 series of motor drivers and development boards. Its representative product, the DM-J4310-2EC, integrates a brushless motor, gearbox, driver, and dual encoders in one unit, communicates over CAN bus, and supports “MIT mode,” which sends position, velocity, stiffness, damping, and feed-forward torque all at once. Because it is inexpensive and simple to wire up, it is common in robot dogs, robot arms, bio-inspired robots, and robotics competitions, and it is a frequent choice for lighter-load joints in many open-source humanoids and open-source robot arms.

ExampleMany open-source dual-arm robots and small humanoids use the DM-J4310 directly for wrist and head joints, controlling it with MIT-mode commands sent over CAN.
