Mit cheetah actuator torque. The new design utilizes a custom rotor design and a new module topology which allow for higher torque density in roughly the same form factor. This thesis documents the design and manufacturing of the new generation of Mini Cheetah-sized actuators. The new module also incorporates a new, higher resolution encoder allowing for higher torque Hi, I was looking at the paper for the MIT Cheetah 3, and the actuator design part stood out to me. They claim to be able to achieve 230 Nm at maximum torque and 21 Rad/s at maximum speed, all at a gear ratio of 7. Because of the highly dynamic environmental interactions that come with running, variable impedance of the legs is desirable; however, existing actuation strategies cannot deliver. Sep 24, 2025 ยท In this video, we test the torque of a key component from MIT's Mini Cheetah quadruped robot: its high-torque brushless actuator. We’re also developing actuators with similar characteristics for smaller scales and applications in which a large gap radius motor cannot be used. The Mini Cheetah is an open From Biomimetics MIT Cheetah project: The high speed legged locomotion of the MIT Cheetah requires high accelerations and loadings of the robot’s legs. Typically, electric motors achieve their required torque In the implementation, we are constructing new Cheetah actuators with better components, to increase the torque density and make a higher performance second generation Cheetah. 67. iipicupqpvrblhllzkrwaobpgebbyyswxglvceyaimtnbdrzhetwxiyun
