The invention discloses an elastically-driven modular joint with force
feedback control. comprising
assembly components such as a motor
stator, a motor rotor, a
harmonic speed
reducer and the like, so that the design flexibility and compactedness of the joint can be increased; and due to the design of an air routing shaft, the joint is convenient to
route, so that the joint is more succinct, the moving range of the joint can be preferably enlarged, and the running reliability of the joint can be improved. Due to the introduction of a first absolute type angle sensor and a second absolute type angle sensor, the angle deviation between an output shaft and an output end cover can be obtained, and the angle deviation is multiplied by the
elasticity coefficient of an elastic
torsion spring, so that a moment value applicable to the joint can be obtained, for an input feedback value of a joint
signal; and a reliable moment feedback
signal can be provided for the joint, so that the elastic
torsion spring can be deformed, the smoothness can be provided for the joint, and an energy storing mechanism can be further provided for the joint, and the elastically-driven modular joint is applicable to a
robot, so that the interaction capability between the
robot and the environment can be enhanced, and the running efficiency of the
robot can be improved.
