1. Restart the robot once.
2. The fault state of the system has not been lifted. Check whether there is a more detailed alarm prompt in the teaching device and handle it.
3. restart.
4. If you still can't let it out, try B to start.
5. If B fails to start, try P to start.
6. If none of the above works, try I startup (this will return the robot to the factory setting state, so please pay attention when using it).
