An example of such a vehicle is a laser guided vehicle, see [1, 3, 9]. The navigation system uses strips of inexpensive reAEector tape (called reAEectors or beacons) which are put on walls or objects along the route of the vehicle. The laser scanner measures the direction from the vehicle to the beacons, but not the distance. This is the information used to ....

....This works, but is very inflexible. To change the path of the vehicle one has to change the wires. Another way that is much more flexible is to use a vehicle that can determine where it is, and which therefore can be moved along any path. An example of such a vehicle is a laser guided vehicle, see [2, 17, 28]. This vehicle is equipped with a laser scanner. A laser beam generated by a vertical laser in the scanner, is deflected by a rotating mirror, at the top of the scanner. Thus, the laser beam scans the room at a fixed height. When the laser beam hits a beacon (a retroreflective tape, also shown in ....

One of the primary vision problems (both 1D and 2D retina) is the so called structure and motion problem. For AGV s this is the ....

Another way that is much more AEexible is to use a vehicle that, from the information where it is, can calculate where it is supposed to move next. An example of such a vehicle is a laser guided vehicle, see [1, 4, 6]. This vehicle is equipped with a laser that rotates and scans a horizontal plane of the premises. The surroundings are equipped with beacons in the form of reAEective tapes. These give rise to reAEections when hit by the laser. The bearing to the beacon relative to the heading of the vehicle is ....

This information is used to calculate the position of the vehicle. One example of an LGV is shown in Figure 1.
