The 3 minute video shows the AGV construction followed by a view of the AGV going around the track. The 14 page application note shows the wiring diagram and the source code of the program that runs in the motor controller. Both are available below.
The MGS1600 sensor measures how far from the centre of the tape it is and provides that information to the motor controller which adjusts the steering so that the vehicle remains at the centre of the track. Magnetic markers positioned on the left and right side of the track give the AGV location information that is used to speed change and fork left/right decisions.
Compared to other guiding techniques, magnetic guides are totally passive and therefore easy to lay and modify. The tape creates an invisible field that is immune to dirt and unaffected by lighting conditions. The magnetic track can be totally hidden under any non-ferrous flooring material, such as linoleum, tiles or carpet.
Mobile Robots using Roboteqs MGS1600 are roaming at major car manufacturing plants, including Honda, Nissan, Mercedes, Seat and Toyota, and at many other companies and institutions.
