Abstract
A safety system of a joint assembly which includes a motor and a brake coupled to the motor is provided. The safety system includes at least one set of sensors configured to detect at least one parameter associated with safety function of the joint assembly, a driving circuit coupled to the motor and the brake and arranged within the joint assembly; and a first processor and a second processor arranged within the joint assembly. The first processor and the second processor configured to receive a signal indicative of the at least one parameter from the at least one set of sensors and send a stop command directly to the driving circuit to stop the motor in response to a joint fault determined based on the signal received from the at least one set of sensors.
