Development of Process Control with Obstacle Avoidance Behavior in Autonomous Mobile Model

Yin Mon Myint


In dangerous area and medical robotic applications, autonomous robots are widely used. The core characteristic of an autonomous system is the ability to detect and successfully avoid the obstacle along the path in moving area and to reach the desired destination. This paper addresses on process control development to drive the model to the destination without any collision. All the process control flow diagrams are included in this paper. To reach the goal, I2C interfacing is implemented among the main functional unit and obstacle detector units. The avoidance process based on line of sight (LOS) to destination and interpolation technique is simulated with MATLAB software. After being some modification to solve the EMI effect and communication problem faced on the whole system testing phase, it can be concluded that the guidance system can totally avoid the obstacles.
