Abstract:

A real-time sensor system plays a critical role for autonomous robot navigation, and location as well. In this paper, a MCU based multi-channel ultrasonic environment finder for autonomous robot is introduced. Some reasons caused the measure error are analyzed, and methods to cope with it are also addressed. By taking advantage of the finder, a small mobile autonomous jeep named SMAJ is developed, experiments show its practicability.

Key words: mobile robot, ultrasonic sensor, micro-controller, unit multi-sensor fusion
