Smart Antennas have internal signal processing and communicate with the steering controller via a CANBUS link.

Also shown the pedestrian laser or "obstacle detection system" (yellow box) used on the front and rear of the vehicle. The system automatically slows the vehicle down and when necessary stops the vehicle. The laser is programmed to sweep the vehicle path within the narrow aisle. Then depending upon the distance of the obstacle from the vehicle - react with the vehicle travel controller accordingly.
