If an obstacle (74) is detected, its position is stored in memory means (41) on the assumption that the obstacle (74) is common to a plurality of vehicles (2, 2). As vehicles (2, 2) passes by, the contents of the memory means (41) are updated. When the vehicles (2, 2) are supplied with position data of their respective goal point (72, 72), the vehicles (2, 2) are guided to their goal point (72, ...

A modulated light source emits light to illuminate a target surface which possesses a certain color and shade of color. Light that is reflected from the target surface is detected by an optical detector. The output from the optical detector is processed and fed back to the optical detector to compensate for any shift caused by ambient light, temperature or other external factors, and is differenti...
