Abstract
An actuator (100) includes a differential (105), the differential comprising a gear train comprising a first leg (106a) and a second leg (106b); a motor (101) configured to power a rotating ball screw (104) through the first leg (106a) of the differential (105); and a brake (103) connected to the second leg (106b) of the differential (105), the brake (103) having a holding force, such that in the event a torque in the differential (105) exceeds the holding force, the brake (103) is configured to dissipate the torque in the differential (105).
