This document describes an automatic pneumatic bumper adjusting system that uses infrared sensors and pneumatic components. The system detects obstacles using an IR transmitter and receiver, then activates solenoid valves and pneumatic cylinders to adjust the position of the bumper. It can stop an oncoming vehicle and requires less human involvement than manual systems. The system has applications for automobiles and industries, providing advantages like lower cost, easier operation and installation, and avoiding wear issues compared to other designs. However, it does require additional upfront costs to implement the automation.
