Problems solved by technology
[0002] In the existing harmonic deceleration device, once an unexpected power failure occurs, the wave generator cannot stop rotating immediately due to inertia, and the motion will still be transmitted to the manipulator, so that the manipulator maintains an inertial motion posture. Power failure of the manipulator has potential safety hazards. In special cases There will be unexpected personal accidents, mechanical failures and property losses
