Abstract: An autonomous electronic device and a method of controlling the motion of the autonomous electronic device thereof are disclosed. The autonomous electronic device includes a motor, a wheel, a processing module, a motor controlling module, and a motion sensor module. The motor is used for driving the wheel. The motor controlling module is used for controlling the motor. The motion sensor module is used for generating a sensing signal according to surrounding conditions encountered by the autonomous electronic device and transferring the signal to the processing module, wherein when the sensing signal is an abnormal movement signal, the processing module controls the motor to adapt to the surrounding conditions via the motor controlling module according to the abnormal movement signal.
