Abstract

Robotics is an exciting field with advancements being made on a continual basis. The question of how an otherwise inanimate entity can be made to move and behave in a certain way, without physical assistance, is the major hindrance that afflicts those wanting to work with mobile robots. As advancements in robotics have been made, various approaches to mobile robot control have been developed each having their own pros and cons. This project delves into the method of reactive control to manage a system with the sole purpose of being able to detect and avoid obstacles in most unstructured environments. The navigation system design is one originally utilised by the supervisor of this project, Dr. Praneel Chand and his counterpart Dale A. Carnegie (Chand and Carnegie, 2005), in a previous undertaking that saw them employ the use of reactive and deliberative control to influence the behaviour of another mobile robot. Experiments to tune the various parameters of the codes were conducted along with several simulation tests. Physical, real world testing was also carried to gauge the robot’s ability to detect and avoid obstacles.
