ATTACHMENT OF GUIDE SENSOR

摘要

PURPOSE:To avoid such a case where a guide sensor touches the road surface or is unable to work even in case an unmanned carrier travels on an extremely uneven road surface by attaching the guide sensor to the legs containing wheels. CONSTITUTION:The legs 3 containing the wheels 2 that can move in the optional direction are attached at two side points of a guide sensor 1. These legs 3 are connected to an axle 5 of the front wheels 4 via a lateral axle pin or can slide with guide of the axle 5. In such a constitution, the sensor 1 is kept away from the road surface by a fixed distance even though the sensor 1 travels on an extremely uneven road. Thus it is possible to avoid such a case where the sensor 1 touches the road surface or an unmanned carrier is unable to travel owing to an improper distance secured between the sensor 1 and a guide.
