Abstract

A remote-controlled motion apparatus is controlled by a remote control apparatus. The remote control apparatus transmits a target motion signal by radio. The remote-controlled motion apparatus includes a communication module, an acceleration sensing module, a processing module and a driving module. The communication module receives the target motion signal from the remote control apparatus. The acceleration sensing module senses an acceleration of the remote-controlled motion apparatus to output an acceleration sensing signal. The processing module is coupled with the acceleration sensing module and the communication module, and processes the acceleration sensing signal and the target motion signal to output a driving control signal. The driving module is coupled with the processing module to receive the driving control signal, and adjusts the driving of the remote-controlled motion apparatus according to the driving control signal.
