    摘要： A system and method to replan coverage paths for a robot operating in an environment with initially unknown static obstacles. Existing coverage approaches reduce coverage time by covering along the minimum number of coverage lines (straight-line paths). However, recomputing such paths online can be computationally expensive resulting in robot stoppages that increase coverage time. An alternative is greedy detour replanning, i.e., replanning with minimum deviation from the initial path, which is efficient to compute but may result in unnecessary detours. In this work, an anytime coverage replanning approach named OARP-Replan is proposed that performs near-optimal replans to an interrupted coverage path within a given time budget. This is accomplished by solving linear relaxations of mixed-integer linear programs (MILPs) to identify sections of the interrupted path that can be optimally replanned within the time budget.

    摘要： A method for collision-free wall-cleaning and/or edge-cleaning by a mobile, self-driving appliance, in particular a floor cleaning appliance for autonomous processing of floor surfaces, such as a robotic vacuum cleaner and/or a sweeping and/or mopping robot, which includes a laterally disposed wall tracking sensor and a distance sensor, includes travelling along a wall section at a first distance determined by measured values of the wall tracking sensor, and simultaneously measuring a second distance to the wall using the distance sensor. A difference is determined between the distance values of the wall tracking sensor and the distance sensor by a computer facility of the appliance. A collision-free distance value with respect to the wall section is determined as a function of the difference by the computer facility. Subsequent cleaning journeys are controlled by a closed-loop distance control as a function of the collision-free distance value that is determined.

    摘要： The invention relates to a floor cleaning system comprising: a self-propelled and self-steering floor cleaning apparatus for cleaning a floor surface; at least one controllable display unit; and at least one storage unit, wherein the floor cleaning apparatus comprises a running gear for traveling on a floor surface, a control unit, a sensor unit, at least one cleaning unit and an operating unit, wherein surroundings can be detected by means of the sensor unit in order to locate and/or navigate the floor cleaning apparatus, in particular during movement, wherein at least one cleaning path on the floor surface can be stored or is stored in the at least one storage unit, wherein the floor cleaning apparatus is designed and configured to create a cleaning path, which can be stored in the storage unit, in a teaching mode of operation while being guided by an operator at the operating unit, and wherein at least one cleaning event relating in particular to the at least one cleaning unit, and/or at least one interaction event relating to an interaction of the floor cleaning apparatus with the surroundings can be stored or is stored in the cleaning path in a position-specific manner, and wherein the cleaning path can be displayed on the at least one display unit in a manner that is associated with the at least one cleaning event and/or the at least one interaction event. The invention further relates to a floor cleaning apparatus and to a method for operating a floor cleaning system or a floor cleaning apparatus.
