After troubleshooting, the parts that need to be repaired by the robot depend on the specific type of failure and the cause. Here are some common faults and their associated repair parts:

Gripping objects are not secure:
Fault: The gripper is faulty or damaged.
Service parts: Grippers may need to be replaced or repaired.
Abnormal motor operation:
Fault: The motor itself is faulty or the supply voltage is unstable.
Service parts: It may be necessary to replace the motor or have the power supply system inspected and adjusted.
Damage to electrical components:
Fault: Damage to electrical components such as relays, switches, sensors, etc.
Repair parts: Replacement or repair according to damaged electrical components.
Controller Failure:
Fault: There is a problem with the controller's power supply, input signal, output signal, etc.
Service Parts: The controller may need to be serviced or replaced.
Sensor Failure:
Faults: Proximity switches, pressure sensors, etc. are faulty.
Service parts: Faulty sensors may need to be replaced.
In addition, the repair of the manipulator may also involve other components, such as lubrication systems, transmission parts, bearings, etc. In the maintenance process, fault analysis and diagnosis should be carried out first, and the cause of the failure and the components involved should be determined, and then the corresponding repair or replacement should be carried out.

In order to ensure the accuracy and effectiveness of the repair, it is recommended to refer to the maintenance manual of the manipulator and the maintenance guide provided by the manufacturer. At the same time, for complex or uncertain faults, it is recommended to seek the help of professional maintenance personnel to ensure the normal operation and prolonged service life of the manipulator.

Please note that the corresponding safety rules and operating procedures should be followed during the maintenance process to ensure the safety of operators.
