Abstract

The purpose of this project is to invent or develop an autonomous vehicle using wall following detection. The autonomous wall following detection robot is one of the mobile robot where is able to get out of the way from the wall or obstacles. This system would be able to maintain a safe distance from a wall, following it around both concave and convex corners [1]. The system would follow the wall to its right, turning right wherever it could, and turning left only when it had to. It would also being able to stop when it finds itself in a place where it cannot move, and reverse moving to enactive and allows the system operates continuously. However, the object of this invention is to provide a robot obstacle detection system which is simple in design, low cost, accurate, easy to implement, and easy to calibrate. Besides, this invention is to provide such a robot detection system which prevents an autonomous wall following detection robot from driving off a stair or obstacle which is too high. The objective of this project is to develop a simulation of a mobile robot that follows the wall to its right. In this project, an autonomous vehicle movement is developed that can be controlled by software using PIC 16F877A programming. In addition, there are four sensors were used for situational awareness. One is mounted on the right side of the vehicle, one on the front, and the other two pointing at 45º degrees to the front left and front right. Troubleshooting and debugging will be conducted until the source codes are successfully developed and execute properly.
