Unitree GO-M8010-6 Review: Specs and Uses of the Robot Joint Motor
Updated: 7 days ago
The Unitree GO-M8010-6 is the integrated joint motor used in Unitree's small quadrupeds, sold as a separate component. Unitree does not list a price on the product page. This review covers its specifications, design and uses.
Quick Verdict
The GO-M8010-6 is a quasi-direct-drive actuator: a flat brushless motor with a low 1:6.33 reduction, a driver and a 15-bit encoder in one housing of about 530 g. The low ratio makes it fast, 30 rad/s, and backdrivable, with 23.7 Nm at peak. This is the kind of joint that makes dynamic legged robots possible, and builders of their own quadrupeds, small arms and exoskeleton prototypes buy it for that reason. It runs on 12 to 30 V and is controlled over RS-485. Its operating range is -5 to 40 °C and no protection rating is given.
