Microcontroller Based Mobile Platform with Fiber Optic Sensors

In the present work a mobile platform with optical fiber sensor was designed, built and tested. The IC 89C51RD2 was used as controller on the platform. The platform was designed with two powered wheels on the back and one free turning wheel on the front. Further the platform was outfitted with proximity, weight and touch plastic fiber sensors. Home position was sensed by touch sensor, the destination by proximity sensor and weight by the load cell sensor. A program was written to move the platform from home position to the destination where after loading the weights in the pan the platform moves back to the destination, unloading the weight the cycle repeats.
