Disclosed is a process for navigating an unmanned vehicle over a predeterable course, respectively such a vehicle. A steering and control unit determines by a first sensor at least the stretch covered and detects by at least one second sensor objects in the vicinage the position of which is stored in the steering and control unit and which serve the purpose of checking the position of the vehicle computed on the basis of the covered stretch. In accordance with the present invention the distance of the vehicle from the objects in the vicinage stored with their exact position in relation to the planned path in the steering and control unit is ascertained by the second sensor at points on the path spaced at intervals. The ascertained distance is compared with the stored distance of the planned coordinates of the point on the path from the object in vicinage.

In a system for detecting the position of an object having predetermined design features in a plane relative to a manipulator provided with ultrasonic sensors consisting of ultrasonic transmitters and ultrasonic receivers, the manipulator is provided with at least three ultrasonic sensors, which are spaced apart and directed at an angle to a common reference plane, two of the sensors are directed to an elongate linear design feature of the object, the third sensor is directed to a second linear design feature of the object, the linear features are designed so that sound waves projected by the ultrasonic sensors and incident on the features will be reflected parallel to the direction of incidence, and the two linear design features are parallel to each other in a plane.
