Definitions

  • the invention relates to a device for determining one's own position and an autonomous mobile system with such a device.
  • a service and cleaning robot For example, as a service and cleaning robot.
  • Driverless transport vehicles are used in block storage areas, for example in the beverage industry.
  • the position of such service robots or driverless transport vehicles can be localized in their respective surroundings.
  • parameters such as driving speed and driving direction can be specified by the navigation system.
  • the navigation system locates the autonomous mobile system based on so-called landmarks, i.e. objects in the environment that can be clearly identified by sensors of the autonomous mobile system. These landmarks are entered on a map known to the navigation system.
  • landmarks i.e. objects in the environment that can be clearly identified by sensors of the autonomous mobile system.
  • Reflectors, transponders or beacons are used as landmarks, which are recognized by a corresponding sensor system. This leads u in highly dynamic environments. This may lead to problems, since landmarks that are permanently attached may be hidden or cannot be attached in such a way that sufficient localization quality is achieved at all positions.
  • DE 43 24 531 C1 discloses a method for creating a map of the environment and for determining a position of its own in the environment by means of a self-moving unit, which uses natural objects from the environment for localization.
  • the invention is based on the object of specifying a device which enables the data used by the navigation system to describe the surroundings to be updated in a simple manner.
  • a device for determining an individual position comprising a navigation system for determining a position in relation to predeterminable information data describing the environment, a memory for storing the information data, and means for
  • Detection of changes in the environment in relation to the information data means for entering changes in the information data and for generating new information data.
  • the invention is based on the knowledge that an autonomous mobile system, such as a service robot or a driverless transport vehicle, must be aware of a current image of the environment at all times in a highly dynamic environment.
  • Mainly moving objects such as pallets serve as natural landmarks for creating a map of the area and for determining one's own position. In addition to the fixed landmarks, these can be used to determine the position if their position in the area can be determined with sufficient accuracy after a change in position.
  • driverless transport vehicles or forklifts move such moving objects as pallets from one position to another.
  • the autonomous mobile systems involved constantly change the environment through their own activities.
  • the changes caused by the autonomous mobile systems themselves can be recorded directly by the systems and existing information data used by a navigation system for determining the position and describing the environment can be updated at the same time.
  • the current lized information data is stored on the autonomous mobile system and is therefore available at any time.
  • a particular advantage here is that the device or the autonomous mobile system for registering and updating positions e.g. No additional hardware is required for moving objects (pallets, barrels or beverage crates). This makes it unnecessary to attach reflectors, beacons or other objects that enable the autonomous mobile system to find its way around.
  • An advantageous embodiment of the invention is characterized in that the information data describing the environment used by the navigation system to determine the position represent variable landmarks and / or unchangeable landmarks.
  • the distinction between changeable and unchangeable landmarks enables certain non-changing landmarks to be stored in the memory as fixed constants, as a result of which a defined framework can be specified in which the autonomous mobile system can orientate and move.
  • a further advantageous embodiment of the invention is characterized in that the device has means for distinguishing between changeable and unchangeable landmarks.
  • the advantage here is that the device is immediately able to recognize which landmarks can and / or may be moved at all. This enables, for example, the device or the autonomous mobile system to be informed of the environment in which it is to operate, that is to say which pallets or beverage crates it is allowed to change its position independently, by entering or marking changeable landmarks. This is advantageous, for example, if only special autonomous mobile systems are allowed to change certain, defined, variable landmarks in their position. In order picking and storage systems with handling of various products, such as Both refrigerated products and other food goods, which may have to be handled differently, can be assigned to specific transport vehicles using warehouse management software.
  • a further advantageous embodiment of the invention is characterized in that the device has means for registering changes in position caused by the device of variable landmarks. This provides the possibility that the device can register the changes caused directly and can change and store information data describing the environment. The device or the autonomous mobile system does not have to be informed by other systems involved that the environment has changed. This enables real-time updates, which are particularly relevant in a highly dynamic environment, to be achieved.
  • a further advantageous embodiment of the invention is characterized in that the device has a receiving device for receiving data transmitted to the device for entering variable landmarks by means of a base unit.
  • This enables data to be transmitted from a base station, in particular changes to the information data describing the environment, to the device.
  • the transmitted data are then updated by the device, ie the new information data are stored in the memory.
  • This possibility of sending data from a base station to the device offers the possibility of supplying several autonomous mobile systems with current data about the environment.
  • an update ie a detection of changes in the information data and the generation of new information data
  • an update is sent from an autonomous mobile system to the base station and that the base station then autonomously transmits this data received from the first autonomous mobile system to all other participants mobile systems transfers.
  • This ensures that all autonomous mobile systems involved can be informed at any time about the current state of their environment. This is advantageous, for example, in a warehouse in which several mobile robots or driverless transport vehicles change the environment at the same time by changing the position of objects or landmarks, i.e. units with products.
  • a further advantageous embodiment of the invention is characterized in that the device has a transmitting device for transmitting updated positions of variable landmarks to the base unit.
  • the device has a transmitting device for transmitting updated positions of variable landmarks to the base unit.
  • a further advantageous embodiment of the invention is characterized in that the provision of the information data shown in the map is provided directly on the device and / or on a base unit.
  • the advantage here is that large amounts of data that arise during the creation of complex maps do not necessarily have to be stored directly on the device, for example an autonomous mobile system or a transport vehicle, but that these large amounts of data are stored on one central memory can be stored on a base unit. This is particularly advantageous in complex environments.
  • central data storage and central updating of the information data used by the navigation system are advantageous.
  • a further advantageous embodiment of the invention is characterized in that the device is intended for use on an autonomous mobile system such as a mobile robot and / or a driverless transport vehicle. This ensures the current status of the information data and a safe movement of the autonomous mobile system in its environment.
