Safety system, joint assembly with safety system, and robot having joint assembly

A joint assembly, comprising:

• a motor;
• a brake coupled to the motor;
• and
• a safety system, wherein 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, and 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;
• wherein the first processor and the second processor are configured to communicate with each other, and send a notification to each other when determining there is a joint failure.

A robot, comprising:

• at least one joint assembly, the at least one joint assembly including a motor, a brake coupled to the motor and a safety system, wherein 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, and 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;
• wherein the first processor and the second processor are configured to communicate with each other, and send a notification to each other when determining there is a joint failure.
