Abstract: The present disclosure relates to a joint assembly and a robot comprising a joint assembly, the joint assembly comprising: a joint housing, a first motor connecting the joint housing with a first link and the first motor being adapted to rotate the first link relative to the joint housing around a first axis, a second motor connecting the joint housing with a second link and the second motor being adapted to rotate the second link relative to the joint housing around a second axis non-parallel with the first axis, circuitry accommodated in the joint housing and comprising a first processing unit and a second processing unit, the first processing unit being adapted to control the first motor and the second processing unit being adapted to control the second motor.
Abstract: A joint assembly for a robot, comprising a housing connected with an output part. The housing comprising a housing wall and a strain wave gearing system. The strain wave gearing system comprising a wave generator, a flexspline, and a circular spline connected to the output part. The wave generator is rotated by a rotor shaft. The rotor shaft is driven by an electric motor comprising a rotor magnet and a stator. The rotor magnet being affixed to the rotor shaft. The joint assembly further comprises one or more sensors comprising one or more magnetic field sensors and one or more pole rings arranged to measure a position of the output part in relation to the housing.
Abstract: The present invention relates to a joint assembly (1) for a robot (100), comprising a housing (26) connected with an output part (8), the housing comprising a housing wall (26A), a strain wave gearing system (90) comprising a wave generator (7), a flexspline (13), and a circular spline (36) connected to the output part (8), wherein the wave generator (7) is rotated by a rotor shaft (3), the rotor shaft being driven by an electric motor (140) comprising a stator (15) and a rotor magnet (16), the rotor magnet (16) being affixed to the rotor shaft (3), and wherein the joint assembly (1) further comprises a rotor brake (30) configured to stop/prevent relative movement between the rotor shaft (3) and the flexspline (13), and sensors arranged to measure the position of the housing (26) in relation to the output part (8).
