Abstract: | The main purpose of this project is to locate and track reliable target features as the robot moves, and keep a record in an internal map describing what features in an indoor environment have been seen and where they are. The new sonar devices proposed by Manyika[3] is used in this project for target tracking. A unified approach to navigation is implemented in this project that combines both localization and map building problems in a common multi-target tracking work. In other words, it likes feature-based navigator, which was proposed by Hallam[2], does not employ an a priori map, but deal with localization and map building simultaneously.
