Abstract: A collision detection apparatus is provided, which includes a main body, at least an air bag disposed at the periphery of the main body and at least a baro sensor. The air bags communicate with each other. The air bag is connected to the baro sensor to detect the pressure at different time points and the pressure variations. The apparatus judges whether a collision has occurred and the collision force is detected by the baro sensors. The time point of collision occurrence and the collision position according to the pressures of the air bags at different time points are determined.

Abstract: A method for detecting and controlling output characteristics of a DC motor is provided in the present invention, wherein an input impedance related to the DC motor is measured for analyzing the output characteristics of the DC motor so that the output characteristics of the DC motor is capable being controlled according to the requirement of usage. By means of the foregoing method, the present invention further provides a self-propelled apparatus which functions to detect and control the output of the DC motor for maintaining the moving speed according to the environment status and road condition.

Abstract: A method for routing a robotic apparatus to a service station and robotic apparatus service system using thereof are disclosed in the present invention, wherein the system comprises at least one service station and a robotic apparatus. The service station is capable of providing charging service and has a signal emitter array which functions to emit communication signals for guiding the robotic apparatus back to the service station. The robotic apparatus has a signal receiver for searching and detecting the communication signal emitted from the service station and determines the moving direction according to the intensity of the communication signal received by the signal receiver so as to arrive at the service station smoothly through the method disclosed in the present invention. Once the robotic apparatus arrives at the service station, the service station may provide service such as charging to the robotic apparatus while the robotic apparatus may standby to wait for the accomplishment of charging.
