EECS373 - Design of Microprocessor-Based System

Autonomous Obstacle Avoidance Vehicle

Autonomous Obstacle Avoidance Vehicle

The vehicle was designed to maneuver around obstructions in it path and be able to navigate itself through a room/hallway without any external control. It does so by using it peripheral sensors .

Peripheral Controller Board

Actel Smartfusion Board

Mounting Plate

How the vehicle operates

The autonomous vehicle by default attempts to move forward without letting itself be trapped or hindered by obstacles in its path. The vehicle pre-emptively moves away from any direction from which it senses an object large enough to be detected by its ultrasonic sensors.

Problems During the Design Process

  • Original Design included GPS unit to specify direction of travel, but resolution was unsuitable for demonstration purposes.

  • Malfunctioning motor controller units

  • Original design lacked sufficient driving power to reasonably operate the vehicle with the total weight of the system.

  • Adjusting the resolution of the ultrasonic sensors the vehicle uses to adjust itself.

(Possible) Future Work

  • Improved obstacle detection using more sonar rangers and higher resolution sonar data.

  • GPS and compass integration to fully realize its pathfinding potential.
