What do you mean, Yuntai is stuck?

It means that the pan/tilt can't move or rotate normally due to obstacles or difficulties in use.

Translation/tilt sticking is caused by mechanical failure, external object interference or other reasons. In the UAV, the PTZ is stuck because the motor of PTZ is overloaded, the protective cover of PTZ has not been removed, and PTZ is stuck by foreign objects. In photographic equipment, the tripod head is stuck because of mechanical parts failure, circuit problems or other factors.
