Abstract: An interactive toy includes a housing, a control module, a motor, a rotating shaft, and an external member. The rotating shaft is exposed outside the housing, and is connected to the external member. The control module is configured to control the motor to drive the rotating shaft to rotate. The toy further includes a measurement module and an analysis module. The measurement module is configured to measure an angle by which the rotating shaft rotates from an initial stationary state to the state in which its rotating speed reaches the maximum. The analysis module is configured to compare a preset reference angle with the angle by which the rotating shaft from the initial stationary state to the state in which the rotating speed of the rotating shaft reaches the maximum to determine whether the external member encounters an obstacle.
