Abstract
An actuator of a robotic system and a robot are provided. The actuator may include a center shaft, an outer shell connected to the center shaft, an input flange, and an output flange coaxially installed on the center shaft, a torque sensor and a motor assembly. The input flange and the output flange are radially fixed with at least one of the outer shell and the center shaft through a plurality of bearings. The torque sensor is connected between the input flange and the output flange, and configured to measure a torque transmitted by the input flange and the output flange. The motor assembly is coupled to the input flange. Disturbances transmitted from either side of the torque sensor may be isolated from the torque sensor. Therefore, the reliability of the readings of the torque sensor may be improved.
