| Abstract: | Design and implementation of seesaw system based on electric vehicle are introduced.The control system consists of AT89S52 single chip computer system,autonomous tracing circuit,balance detection circuit,driving circuit of stepping motor and LED display circuit.Centering on AT89S52,the track detection is realized by reflective infrared emitter and receiver and the steering of the vehicle is driven by stepping motor.The detection of balance state is implemented by two mercury switches and the travel time is displayed with LED separately.The scheme is proved to be effective and practical by experimental results during three tests. |
