FAQ
Design to rated or peak torque?
Rated. Peak is a seconds-long burst figure; continuous motion happens at rated torque, and QDD modules heat up at stall. Design to 9 Nm, celebrate 18.
Why is this the research default?
Most published legged-robot baselines were built on AK-series modules, so matching them saves weeks of controller retuning. Innovate on the robot first, the joint later.
