AI summary

A remote control device for remotely controlling an unmanned apparatus and a carried object carried by the unmanned apparatus includes a remote control device attitude sensor and a microprocessor. The remote control device attitude sensor is configured to detect a remote control device spatial attitude of the remote control device and output a remote control device spatial attitude signal according to the remote control device spatial attitude. The microprocessor is configured to receive the remote control device spatial attitude signal, calculate an angle change of the remote control device in a remote control device dimension based on the remote control device spatial attitude signal, and generate a carried object control signal for controlling a movement of the carried object in a corresponding dimension based on the angle change of the remote control device. The corresponding dimension corresponds to the remote control device dimension.
