  • Patent number: 11760221
    Abstract: An autonomous robot moves materials in a warehouse or other industrial environment. It runs on an electric motor powered by a rechargeable battery. When its battery becomes depleted, it maneuvers to a nearby charger. It guides itself to the charger using visual cues, such as a target on or near the charger, until it establishes a good electrical connection with the charger. Proximity sensors on the charger and/or the autonomous robot determine if the autonomous robot is positioned properly; if so, the charger begins charging the autonomous robot's battery. While charging, the charger monitors the resistance of the electrical connection for open- or short-circuit conditions. It also monitors the status of the proximity sensors. If the charger detects an open-circuit or a short-circuit or that the autonomous robot has moved away from the charger, the charger stops charging.

  • Patent number: 11172646
    Abstract: The invention relates to a system to carry out a floor related action. The system comprises an animal enclosure for detaining at least one animal and provided with an enclosure floor surface, a first autonomous vehicle configured to navigate over the floor surface to carry out the floor related action, and a feed providing device to provide feed to the animal. The system comprises a communication signal configured to transmit a communication signal representative for an actual or planned feeding action of the feed providing device to the first vehicle, which action influences the position of animals with the animal enclosure. In order to move the first vehicle more efficiently over the stable floor, in particular to avoid interference with animals on the stable floor, the first vehicle is capable to adapt its navigation based on the communication signal representative for the actual or planned feeding action.

  • Patent number: 11163301
    Abstract: In a method for operating a self-traveling floor treatment apparatus, a recording device of the floor treatment apparatus records a recording of an environment of the floor treatment apparatus, which concerns a time period, and the recording is displayed for a user of the floor treatment apparatus on a screen. In order to allow correction of error conditions, the recording is stored and, in case of a defined environmental event and/or apparatus condition of the floor treatment apparatus, a time-defined partial sequence is subsequently extracted from the stored recording and displayed on the screen.

  • Patent number: 11154008
    Abstract: In one aspect, a system for operating an agricultural harvester may include a sensor assembly configured to detect a parameter indicative of an operating line of the harvester. The system may also include a controller configured to monitor the operating line of the harvester based on measurement signals received from the sensor assembly when the harvester is operated in a first operating mode. The controller may also be configured to determine a differential between the operating line and a predetermined guidance line of the harvester. Furthermore, the controller may be configured to update a stored correction value based on the determined differential. Additionally, when the harvester is switched from the first operating mode to a second operating mode, the controller may be configured to adjust a location of the predetermined guidance line based on the stored correction value.

  • Patent number: 11109734
    Abstract: A combined robot includes a self-moving robot and a functional module, in which the functional module is detachably combined into the self-moving robot through a connecting piece. Driving wheels and a driven wheel are disposed at a bottom of a machine body of the self-moving robot. By taking an advancing direction when the self-moving robot operates as a forward direction, the driving wheels are located on a left side and a right side of the bottom of the machine body. The driven wheel is located at a front end or a rear end of the bottom of the machine body. A control center is disposed in the combined robot and controls the combined robot to operate. One end away from the driven wheel of the bottom of the machine body of the self-moving robot is a supporting end, and floating supporting mechanisms are disposed at the supporting end.

  • Patent number: 11020857
    Abstract: The present disclosure provides a robot distance measuring method and apparatus as well as a robot using the same. The method includes: obtaining a plurality of relative position parameters of a robot from a plurality of ranging sensors; determining an installation distance between each two of the ranging sensors based on the plurality of relative position parameters; determining a sum of the installation distance of each looping arrangement of the plurality of ranging sensors based on the installation distance between each two of the ranging sensors; and enabling the plurality of ranging sensors sequentially to perform obstacle ranging according to a preset looping rule. Since the adjacent ranging sensors are avoided to range simultaneously or sequentially, the interference of the adjacent ranging sensors can be minimized, the accuracy of measuring the distance of the surrounding obstacles can be improved, thereby improving the navigation performance of the robot.

  • Patent number: 11013390
    Abstract: Provided herein a vacuum cleaner capable of effectively escaping from a situation where driving wheels are in an idling state. The vacuum cleaner includes a main casing, driving wheels, a control unit and an idling detection part. The driving wheels enable the main casing to travel. The control unit controls the driving of the driving wheels to make the main casing autonomously travel. The idling detection part detects that the driving wheels are in an idling state. In the case where the idling detection part detects that the driving wheels are in an idling state, the control unit controls the operation of the driving wheels so as to, after the operation to make the main casing retreat by a certain distance, repeat consecutively for a plurality of times the operation to make the main casing turn in a specified one direction and advance by a specified distance.
