Abstract
A wrist mechanism includes a first rotation unit, a second rotation unit, a first brake pad, and a first brake plate. The first rotation unit includes a first motor, a first rotating shaft that is connected to the first motor, and a first encoder. The first motor is operable to drive the first rotating shaft to rotate about a first axis. The first encoder measures an angle of rotation of the first rotating shaft. The second rotation unit is co-rotatable with the first rotating shaft about the first axis. The first brake pad is connected to the first rotating shaft. The first brake plate is operable to move relative to the first brake pad along the first axis. When the first brake plate is urged to move along the first axis to abut against the first brake pad, the rotation of the first rotating shaft is stopped.
