Die wenigstens drei (Mecanum-)räder können als Mecanumrad insbesondere jeweils einen Rollenträger aufweisen, der um eine Raddrehachse drehangetrieben am Fahrgestell gelagert ist und die jeweils mehrere gleichmäßig über einen Umfang verteilt angeordnete, am Rollenträger unangetrieben um deren Rollendrehachsen drehbar gelagerte Rollen aufweisen.The at least three (Mecanum) wheels can each have a roller carrier as a Mecanum wheel, which is mounted on the chassis in a rotationally driven manner about a wheel axis of rotation and which each have a plurality of rollers arranged uniformly distributed over a circumference and rotatably mounted on the roller carrier in an undriven manner about their roller axes of rotation.
Jedes Mecanumrad kann auf dem Umfang des Rades, die insoweit eine Art Felge bildet, mehrere drehbar gelagerte tonnenförmige Rollen aufweisen, die vorzugsweise im Winkel von 45 Grad zur Radachse drehbar am Rad gelagert sein. Ausschließlich diese tonnenförmigen Rollen stellen den Kontakt zum Boden her. Diese tonnenförmigen Rollen haben keinen direkten Antrieb und können sich frei um ihre schrägen Lagerachsen drehen. Das gesamte Mecanum-Rad, d.h. die Felge, wird dagegen von einem Antriebsmotor mit variabler Drehzahl und jeweils gewünschter Drehrichtung angetrieben.Each Mecanum wheel can have several rotatably mounted barrel-shaped rollers on the circumference of the wheel, which forms a kind of rim, which are preferably mounted rotatably on the wheel at an angle of 45 degrees to the wheel axis. Exclusively these barrel-shaped rollers make contact with the ground. These barrel-shaped rollers have no direct drive and are free to rotate about their slanted bearing axles. The entire Mecanum wheel, ie the rim, on the other hand, is driven by a drive motor with variable speed and the desired direction of rotation.
Die Steuervorrichtung kann ausgebildet und eingerichtet sein, die omnidirektionale mobile Fahrplattform automatisch und autonom auf einem Boden beispielsweise einer Halle, eines Platzes, einer Tiefgarage oder einer Parkhauses zu bewegen d.h. zu fahren. Ein automatisches Fahren bedeutet, dass die omnidirektionale mobile Fahrplattform sich aufgrund eines selbsttätig ablaufenden Bewegungsprogramms und/oder einer selbsttätig ablaufenden Fahrstrategie selbstgesteuert und zielgerichtet bewegen kann. Ein autonomes Fahren bedeutet, dass die omnidirektionale mobile Fahrplattform insoweit selbstbestimmt und unabhängig von einem Eingreifen durch eine Person fährt, d.h. die omnidirektionale mobile Fahrplattform bewegt sich fahrerlos. Ein Navigieren, Antizipieren und Kompensieren der Bewegungen, d.h. der Fahrten der omnidirektionale mobilen Fahrplattform erfolgt demgemäß ohne das Eingreifen einer Person oder Fahrers.The control device can be designed and set up to move, i.e. to drive, the omnidirectional mobile driving platform automatically and autonomously on a floor, for example a hall, a square, an underground car park or a multi-storey car park. Automatic driving means that the omnidirectional mobile driving platform can move in a self-controlled and targeted manner due to an automatically running movement program and/or an automatically running driving strategy. Autonomous driving means that the omnidirectional mobile driving platform drives in a self-determined manner and independently of any intervention by a person, i.e. the omnidirectional mobile driving platform moves without a driver. Accordingly, navigating, anticipating and compensating for the movements, i.e. the journeys, of the omnidirectional mobile driving platform takes place without the intervention of a person or driver.
Das Fahrgestell der omnidirektionale mobilen Fahrplattform kann einerseits als ein Teil des Fahrwerks verstanden werden, an dem die Mecanum-Räder gelagert sind und andererseits aber auch als Grundstruktur, Chassis und/oder Gehäuse der omnidirektionale mobilen Fahrplattform verstanden werden. Das Fahrgestell der omnidirektionale mobilen Fahrplattform kann insoweit auch einen Grundrahmen, ein Gehäuse, innenliegende Hohlräume und/oder äußere Aufnahmebereiche umfassen. Auch eine Tragplattform kann im Rahmen der Erfindung als Teil des Fahrgestells betrachtet werden.The chassis of the omnidirectional mobile driving platform can on the one hand be understood as a part of the chassis on which the Mecanum wheels are mounted and on the other hand can also be understood as the basic structure, chassis and/or housing of the omnidirectional mobile driving platform. In this respect, the chassis of the omnidirectional mobile driving platform can also comprise a base frame, a housing, internal cavities and/or external receiving areas. A support platform can also be considered part of the chassis within the scope of the invention.
Indem die omnidirektionale mobile Fahrplattform wenigstens eine mit dem Fahrgestell verbundene Kopplungsvorrichtung aufweist, die ausgebildet ist, zum Koppeln wenigstens einer separaten Arbeitsvorrichtung mit der omnidirektionalen mobilen Fahrplattform, um die mittels der Kopplungsvorrichtung angekoppelte Arbeitsvorrichtung in der Umgebung der omnidirektionalen mobilen Fahrplattform autonom zu bewegen und zwar angesteuert durch die Steuervorrichtung der omnidirektionalen mobilen Fahrplattform, und die wenigstens eine separate Arbeitsvorrichtung eine zur Ansteuerung der Arbeitsfunktionen der Arbeitsvorrichtung eigene Arbeitssteuerung aufweist und die Steuervorrichtung der omnidirektionalen mobilen Fahrplattform ausgebildet und eingerichtet ist, unter Berücksichtigung von Steuerbefehlen der Arbeitssteuerung, die omnidirektionale mobile Fahrplattform auf einem Boden in Abhängigkeit ihrer Umgebung autonom zu navigieren, kann eine sehr effiziente Aufgabenaufteilung zwischen der omnidirektionalen mobilen Fahrplattform und der Arbeitsvorrichtung erreicht werden. Indem die Kopplungsvorrichtung ausgebildet ist, unterschiedlichste Arbeitsvorrichtung mit der omnidirektionalen mobilen Fahrplattform verbinden zu können, kann der Nutzungsumfang der omnidirektionalen mobilen Fahrplattform weitgehend beliebig erweitert und/oder ergänzt werden. Dabei obliegt es jedoch stets der omnidirektionalen mobilen Fahrplattform bzw. der Steuervorrichtung der omnidirektionalen mobilen Fahrplattform sich in der Umgebung zurechtzufinden, das heißt kollisionsfrei, zielgerichtet und sicher von einem Ausgangsort zu einem Zielort zu fahren.The omnidirectional mobile driving platform has at least one coupling device connected to the chassis, which is designed to couple at least one separate working device to the omnidirectional mobile driving platform in order to autonomously move the working device coupled by means of the coupling device in the vicinity of the omnidirectional mobile driving platform, specifically controlled by the control device of the omnidirectional mobile driving platform, and the at least one separate working device has its own working control for controlling the working functions of the working device and the control device of the omnidirectional mobile driving platform is designed and set up, taking into account control commands of the working control, the omnidirectional mobile driving platform on a floor navigating autonomously depending on their environment can be a very efficient division of tasks between the omnidirektio nal mobile driving platform and the working device can be achieved. Since the coupling device is designed to be able to connect a wide variety of working devices to the omnidirectional mobile driving platform, the scope of use of the omnidirectional mobile driving platform can be largely expanded and/or supplemented as desired. However, it is always the responsibility of the omnidirectional mobile driving platform or the control device of the omnidirectional mobile driving platform to find their way around in the environment, ie to drive from a starting point to a destination in a collision-free, targeted and safe manner.
Andererseits ist zum jeweils individuellen Funktionsbetrieb der jeweiligen Art der Arbeitsvorrichtung eine "Arbeitsintelligenz" erforderlich, die erfindungsgemäß in der Arbeitsvorrichtung enthalten ist. Somit ist es nicht erforderlich, dass die omnidirektionale mobile Fahrplattform bzw. die Steuervorrichtung der omnidirektional mobilen Fahrplattform alle benötigten "Arbeitsintelligenzen" der mehreren Arbeitsvorrichtungen selbst aufweisen muss. Die jeweilige individuelle "Arbeitsintelligenz" ist vielmehr in der jeweiligen individuellen Arbeitsvorrichtung untergebracht. Unter "Arbeitsintelligenz" können alle technischen Funktionen und/oder Betriebsabläufe verstanden werden, die von der Arbeitssteuerung gesteuert werden, um die spezifischen Funktionen der jeweiligen Arbeitsvorrichtung automatisch ausführen zu können. So sind beispielsweise im Falle einer Scheuersaugvorrichtung die Fahrgeschwindigkeit der Scheuersaugvorrichtung, die Bewegungsgeschwindigkeit von Bodenbearbeitseinrichtungen, insbesondere die Drehzahl drehender Bodenbearbeitseinrichtungen, wie bspw. sich bewegende oder drehende Bürsten, und die Menge der automatisch aufgebrachten Flüssigkeiten, wie Frischwasser und/oder Reinigungsflüssigkeit für die Reinigungswirkung und das Reinigungsergebnis von Bedeutung.On the other hand, a "working intelligence" is required for the respective individual functional operation of the respective type of working device, which according to the invention is contained in the working device. Thus, it is not necessary for the omnidirectional mobile traveling platform or the control device of the omnidirectional mobile traveling platform to be all required Must have "work intelligence" of multiple work devices themselves. Rather, the respective individual "working intelligence" is accommodated in the respective individual working device. "Working intelligence" can be understood to mean all technical functions and/or operating processes that are controlled by the work controller in order to be able to automatically execute the specific functions of the respective work device. For example, in the case of a scrubber drier, the driving speed of the scrubber drier, the speed of movement of floor treatment devices, in particular the speed of rotating floor treatment devices, such as moving or rotating brushes, and the amount of liquids automatically applied, such as fresh water and/or cleaning liquid for the cleaning effect and the cleaning result is important.
Diese Funktionen werden von der Arbeitssteuerung der Scheuersaugvorrichtung gesteuert. Beispielsweise im Hinblick auf die Funktion der Fahrgeschwindigkeit der Scheuersaugvorrichtung sendet in einem erfindungsgemäßen Verbundbetrieb von omnidirektional mobiler Fahrplattform und Arbeitsvorrichtung, d.h. Scheuersaugvorrichtung, die Arbeitssteuerung der Scheuersaugvorrichtung die erforderlichen Fahrgeschwindigkeitsbefehle an die Steuervorrichtung der omnidirektional mobilen Fahrplattform, so dass die omnidirektional mobile Fahrplattform bzw. die Steuervorrichtung die für die Arbeitsvorrichtung, d.h. Scheuersaugvorrichtung erforderliche Fahrgeschwindigkeit vorgeben kann, d.h. die omnidirektional mobile Fahrplattform in genau derjenigen Fahrgeschwindigkeit fahren lässt, die von der Arbeitsvorrichtung, d.h. Scheuersaugvorrichtung vorgegeben wird und in der die Arbeitsvorrichtung, d.h. die Scheuersaugvorrichtung insoweit "ohne weitere eigene Navigations-Intelligenz" der Fahrt bzw. der Fahrgeschwindigkeit der omnidirektional mobilen Fahrplattform folgt.These functions are controlled by the scrubber-drier work controls. For example, with regard to the function of the driving speed of the scrubbing device, in a combined operation according to the invention of an omnidirectional mobile driving platform and working device, i.e. scrubbing device, the working control of the scrubbing device sends the required driving speed commands to the control device of the omnidirectional mobile driving platform, so that the omnidirectional mobile driving platform or the control device can specify the driving speed required for the working device, ie the scrubber drier, ie lets the omnidirectional mobile driving platform drive at exactly that driving speed which is specified by the working device, ie the scrubber drier and in which the working device, ie the scrubber drier to the extent "without any additional navigation intelligence of its own " follows the journey or the driving speed of the omnidirectional mobile driving platform.
Somit benötigen die einzelnen Arbeitsvorrichtungen auch keine Kenntnis und keine eigenen Navigations-Steuerfunktionen von der Umgebung, in der sich der Verbund bewegen soll. Dies vereinfacht auch die Ausgestaltung der individuellen Arbeitsvorrichtungen. Ggf. benötigen dann die Arbeitsvorrichtungen auch keine eigenen Navigationssensoren und keine eigenen Navigationssteuerungen.Thus, the individual working devices do not need any knowledge or their own navigation control functions of the environment in which the group is to move. This also simplifies the design of the individual working devices. The working devices may then also not require their own navigation sensors and their own navigation controls.
Die separate Arbeitsvorrichtung kann demgemäß eine Scheuersaugvorrichtung sein, die einen automatisch auffüllbaren Frischwassertank, einen automatisch auffüllbaren Reinigungsmitteltank und wenigstens eine Flüssigkeitsapplikationseinrichtung aufweist, die ausgebildet ist, Wasser aus dem Frischwassertank, Reinigungsflüssigkeit aus dem Reinigungsmitteltank und/oder eine Mischung aus Wasser und Reinigungsflüssigkeit auf den Boden aufzutragen, und des Weiteren eine Bodenbearbeitungseinrichtung aufweist, die ausgebildet ist, auf den Boden einzuwirken, um den mit der Reinigungsflüssigkeit versehenen Boden zu reinigen und zwar gemäß eines in der Arbeitssteuerung hinterlegten Reinigungsprogramms.Accordingly, the separate working device can be a scrubbing device that has an automatically refillable fresh water tank, an automatically refillable cleaning agent tank and at least one liquid application device that is designed to apply water from the fresh water tank, cleaning liquid from the cleaning agent tank and/or a mixture of water and cleaning liquid to the floor applied, and further comprises a floor treatment device which is designed to act on the floor in order to clean the floor provided with the cleaning liquid, specifically in accordance with a cleaning program stored in the work control.

Weiterhin wird durch den modularen Ansatz eine Multifunktionalität erreicht, der die Amortisationszeit reduziert und einen Mehrwert für den Parkhausbetreiber generiert. Damit wird ein vollständig autonomer Betrieb ermöglicht, die Reinigung wird in reproduzierbarer Qualität durchgeführt. Durch weitere Module die mit identischer Schnittstelle an die Plattform gekoppelt werden können, sind weitere Servicedienstleistungen realisierbar.In this respect, the invention can consist of a modular platform which is either expanded by a cleaning module or upgraded directly to a cleaning unit for underground car parks. Known solutions only include manual or semi-automated cleaning operations. In addition to navigating in the parking garage environment and automatically filling with cleaning agent, the solution according to the invention enables completely autonomous operation. Furthermore, the modular approach achieves multifunctionality, which reduces the amortization period and generates added value for the car park operator. This enables fully autonomous operation, and cleaning is carried out with reproducible quality. Additional services can be implemented using additional modules that can be linked to the platform with an identical interface.
