Abstract
An actuator assembly is disclosed herein. The assembly includes a motor shaft; support; harmonic drive connected to the motor shaft that includes an output connected to a drive shaft defining a first sun gear; drive mechanism; and actuator arm. The drive mechanism includes a first gear set and a second gear set. The first gear set has a first carrier including a second sun gear. The first carrier supports a first plurality of planetary gears that engage both the first sun gear and a first ring gear rotationally fixed to the support. The second gear set has a second carrier fixed to the support. The second carrier supports a second plurality of planetary gears that engage both the second sun gear and a second ring gear. The actuator arm is connected to the second ring gear such that the actuator arm is rotationally driven by the motor shaft.
