- Such sensor devices can consist, for example, of optical sensor devices using a laser beam for scanning (for example in the horizontal plane) and / or of ultrasonic sensors, radar sensors or the like. In particular in the present time, sensors based on a camera with a silicon chip could even be used to evaluate the recorded image.
- the preferably comparable to a robot, which can be moved automatically and thus automatically, especially in the form of a work or cleaning machine, is characterized by the fact that at least m dependent speed when cornering or pivoting an actuating, working or cleaning unit provided on the vehicle, preferably in the form of a working or cleaning head, which at least one sensor device is pivoted at least relatively in the same direction.
- the pivoting process can take place in direct coupling to the angle of the direction of travel or the rotation of the working or cleaning head.
- At least one sensor device for example a laser sensor near the floor, in particular at the level of the wheels or slightly above, for example up to approximately the level of a chassis or floor of the working device or the cleaning machine.
- This can be a laser scanner that automatically works in a horizontal angular range and scans the surroundings.
- this sensor for example in the form of a laser scanner, already scans the surroundings in a wide-angle range from left to right (generally symmetrical to the central longitudinal axis) when driving straight ahead, the solution according to the invention offers considerable advantages.
- the advantage according to the invention shows especially when cornering or swiveling the work or cleaning head, because according to the invention the sensor is also swiveled.
- This allows the sensed sensor field to be designed to be comparatively small from the start and even to provide certain blind spots to the side, for example when monitoring and scanning the area to the left is swung to the left, i.e. the dead zones that are otherwise located when driving straight ahead are also covered
- At least one or preferably a plurality of higher-lying sensor devices is provided, which is arranged, for example, in front of the paneling of the automatically movable carriage or the cleaning device.
- This can be a tree-like or columnar structure, which is coupled to the steering or pivoting direction of the steering mechanism and / or the pivotable working or cleaning head.
- the sensor can pillar, that is, for example, pivoted with j and in each case running direction are aligned.
- this higher-lying sensor device can also be arranged underneath a covering of the automatically movable working or cleaning device if at least parts of the cover, behind which the sensor devices relevant to the decision are located, are quasi "transparent" for this sensor device or at corresponding points Window openings are provided. The only thing that is important is that a sufficient the corresponding sensor devices can be pivoted alongside such a cladding of the working or cleaning device.
- the invention is described above all in the case of a preferably self-propelled work or floor cleaning machine. But the invention can equally be applied for j edes movable vehicle, in particular a selbs wheeled vehicle. These may include, gungs- automatically traversing ⁇ bare lawn sprinkling systems, Agrarmaschmen, Congressremi- or machines, snow plow vehicles, etc. A limitation to certain movable vehicles or work or cleaning machines is not given examples play as well as lawn mowers.

- Figure 2 is a side view of the exemplary embodiment game of Figure 1;
- FIG. 3 a top view of the exemplary embodiment according to FIGS. 1 and 2;
- Figure 4 is a view corresponding to figure 3 plan view, j edoch not at straight running, but with left turn drive; and FIG. 5: a partially schematic side illustration to explain that the sensor device and the sensor tree can also be designed as a tactile sensor element and / or an additional sensor element, in particular a tactile sensor element, can be provided in order to scan the ground.
- FIGS. 1 to 4 show exemplary embodiments of a floor treatment or floor cleaning device which, in terms of its basic structure, corresponds to the floor cleaning machine known from the previously published international PCT application WO 98/43527.
- a floor cleaning machine of this type has a processing head 3 which can be pivoted about a vertical axis, the cleaning head also being able to be pivoted together about the vertical pivot axis via a roller 5 which can also be pivoted.
- the vertical pivot axis is preferably offset from the vertical diameter by the roller which can also be pivoted.
- Such an automatic and automatically movable soil tillage implement can only be used in practice if it can react independently to obstacles in the cleaning area. This first requires the detection of such obstacles. Such obstacles can be caused, for example, by people in the cleaning area or by objects that have been repositioned, set up or moved elsewhere, etc.
- the tillage device according to FIGS. 1 to 4 comprises a first lower sensor device 13, which can consist, for example, of a laser scanner.
- the sensor device 13 and an associated scanning field 15 are shown, along which the laser beam is permanently and automatically moved back and forth by the laser scanner.
- a specific spacing frame can be used to detect from the actual sensor 13 by evaluating reflection light whether there are obstacles in this area.
- a second sensor device 17 is provided, which is arranged above the first sensor device 13 in the exemplary embodiment shown.
- the second sensor device comprises a columnar structure with a plurality of sensor devices 23 formed there and, for example, one above the other on the opposite side areas 19 and in the front area 21, for example in the form of ultrasonic sensor devices 23.
- the so-called second sensor device 17 is preferably above the chassis 25, that is to say above the bottom surface, in the exemplary embodiment shown above the wheels 7, and extends there when driving straight ahead in the central longitudinal plane of symmetry, the plurality of sensors 13 arranged on the front and on the opposite sides 19 being arranged more or less vertically one above the other, in the exemplary embodiment shown on a kind Sensor column 27.
- This sensor column 27 is connected to the processing or cleaning
- the supply head is also firmly connected to a swivel, in the exemplary embodiment shown it is mounted directly on the first sensor device 13, so that the first and second sensor devices are automatically aligned with the direction of cleaning and travel when the work or cleaning head 3 is turned or pivoted accordingly.
- the overall structure is such that the working or soil working head 3 can be swiveled from left to right by means of a vertical swiveling axis arranged below the chassis 25, this swiveling head protruding beyond the front boundary 29 (FIG. 2) when driving straight ahead and mentioned second sensor device 17 is held and mounted on this protruding sensor support section 31.
- the arrangement, including the front cover 33 of the tillage implement, is such that, even when pivoted to the side, this second sensor device 17, for example in the form of the sensor column 27, cannot collide with the cover 33.
- the corresponding pivoting movement to the left shows the simultaneous pivoting of the first sensor device 13 with the corresponding alignment of the scanning field 15 and the joint pivoting of the second sensor device 17 formed on the sensor column 27.
- FIG. 5 corresponds to the side view according to FIG. 4.
- the sensor device 13, 17 acts overall as a tactile sensor element 41.
- the movable carriage for example in the form of the explained soil cleaning machine, approaches an object which, for example, also protrudes above the floor in the direction of the machine, either the sensor tree in the form of the second sensor device 17, or the one that protrudes upwards, can be used the first sensor device 13 located below when in contact with the object in question - since both units are designed together or separately as tactile sensor devices 41 - trigger a corresponding signal in order to stop the further forward travel and, if necessary, to move backwards and then laterally, for example, especially if it is a self-propelled driving device.
