| 總結: | The key concern of this project is the design and development of the technology of
pneumatics which plays a major role in the field of automation, modern machine shops
and space robots. The aim is to develop a control system based on intelligent and
electronically controlled pneumatic bumper and braking system. This project consists
of ultrasonic transmitter and receiver circuit, control unit, solenoid valve, pneumatic
bumper system and pneumatic braking system. The ultrasonic sensor senses the
obstacle closer to the vehicle (within 4-7 feet), then the control signal is given to the
pneumatic bumper as well as pneumatic braking system simultaneously. This bumper
and braking system is activated only when the vehicle speed is above 40-50 km per
hour. This vehicle speed is sensed by the ultrasonic sensor and it is given to the control
unit. The control unit controls the solenoid valve so that the pneumatic bumper and
braking system is actuated.
