Title:
AUTONOMOUS TRAVELING SERVICE CAR
Document Type and Number:
Japanese Patent JP2003167628
Kind Code:
A
Abstract:

To surely prevent the collision of a traveling object with its surrounding obstacle regardless of the outer peripheral size of the main body of the travelling object even when the setting space of a range means for detecting the obstacle is limited due to the size of the main body of the traveling object, and the short range insensitive range of the range means is spread beyond the outer periphery of the main body.

An autonomous traveling service car is provided with a driving means for moving this main body, a range means with a limit value for short range measurement for measuring a distance between the surrounding of the main body and an obstacle, and a traveling control means for controlling the traveling of the main body by the driving means based on information from the range means. In this case, the stop of the traveling of the main body is controlled with the value of the distance measured by the range means larger than the minimum distance being the limit value of the distance measuring means. The setting position of the range means is made movable inside the main body. This autonomous traveling service car is also provided with a storage means for storing a prescribed value for controlling the stop of traveling, an input means for changing the prescribed value from the outside, an ultrasonic range sensor for measuring a relatively long distance right and left, and an optical range sensor for measuring a relatively short distance to compensate for the dead angle of the ultrasonic sensor positioned between them.
