Humanoid robots, designed to operate in close interaction with humans, rely heavily on smooth and controlled joint and limb motion. This makes the selection of the motors that power the axes of motion critical. Alongside high torque density and responsiveness, efficiency to enable long battery life is key, and reliability is also important. Achieving freedom of movement requires integrating numerous axes of motion, which is best accomplished by working closely with an expert in this field.

Closed Loop control systems can handle a wide range of motions with a wide range of loads if the control system and mechanics are properly designed for the task. A couple of the more difficult combinations to design for are high inertial mismatches and backlash with hard gearing. The question is not just how to make the system stable, but rather how to also get the desired performance.
