Motor and controller integration for a legged robot

This invention describes a compact robotic joint where the motor and its electronic controller are built into the same housing. The controller's power components are positioned to face the motor, and a sensor on the controller reads the motor's exact position using a diametrically magnetized magnet embedded in the motor's rotating shaft. The controller itself is specified to use separate power and logic circuit boards.

Why it matters: Since 2019, advances in power electronics and miniaturized thermal management make such compact, high-power-density robotic joints more practical, addressing a persistent need for integrated robot actuators.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
