Patent number: 11402850Abstract: A system and method of causing a robotic device to navigate an area, including accessing a map of an area of travel, causing a transport assembly of the robotic device to move the robotic device in the area at a first speed, collecting information about the area as the robotic device moves in the area by at least one sensor, and processing the information collected. The system and method also include comparing the information collected with the information regarding the area from the map, and determining a degree of confidence that the information collected matches the information regarding the area of travel from the map. When the determined degree of confidence is at or below a first threshold degree of confidence, a first reduced speed mode of operation causes the transport assembly of the robotic device to move at a second, lower speed.Type: GrantFiled: December 8, 2017Date of Patent: August 2, 2022Assignee: Diversey, Inc.Inventors: Aurle Gagne, Philip Scarim, David M. Knuth, Jr., Philip J. Hennessy, Anthony T. Bavuso, Stephen J. Balas

Patent number: 11253124Abstract: A cleaning unit for cleaning floors comprising a drivetrain, a main controller, a safety module, and one or more cleaning aggregates for cleaning a floor upon which the cleaning unit moves. The main controller may operate the cleaning unit in one of an autonomous mode in which cleaning unit autonomously navigates while cleaning the floor or a manual mode in which the cleaning unit is maneuverable under an applied external force while cleaning the floor. The safety module may be responsive to a plurality of safety inputs such that if a safety input indicates an unsafe condition, the safety module initiates a lockout to stop movement by the cleaning unit. In the autonomous mode, the safety module may be responsive to a first set of safety inputs and in the manual operating mode, the safety module may be responsive to a second set of safety inputs.Type: GrantFiled: March 9, 2018Date of Patent: February 22, 2022Assignee: Diversey, Inc.Inventors: David M. Knuth, Stephen D. Herr, Stephen J. Balas, Angelo Sabatino, Marcel Graf, Andre Baertsch, Sepp Stary

Patent number: 11097433Abstract: A robotic device comprising a long-range sonar assembly configured to detect objects between 1000 mm to 9500 mm from the long range sonar assembly. The long-range sonar assembly comprises a flared bell housing and a transducer. The robotic device also comprises a transportation mechanism configured to move the robotic device in various directions in response to instructions from a processing device that is in communication with the ling-range sonar assembly and the transportation mechanism. The processing device may cause the long-range sonar assembly to, via the transducer transmit one or more pulses and receive the one or more pulses as echo pulses having reflected off an object in an environment. The processing device may then cause a transmitter to transmit instructions to the transportation mechanism to move the robotic device in the environment based on the received one or more pulses.Type: GrantFiled: December 3, 2018Date of Patent: August 24, 2021Assignee: Diversey, Inc.Inventors: Stephen J.

Publication number: 20210132609Abstract: An autonomous vehicle is configured to move across a floor surface in an environment. The autonomous vehicle includes a proximity sensor that is positionable at different heights on the autonomous vehicle. A location of the autonomous vehicle within the environment is determined. A proximity sensor height is determined based on the location of the autonomous vehicle within the environment. The proximity sensor is positioned at a height on the autonomous vehicle based on the proximity sensor height. A signal is received from the proximity sensor where the signal is indicative of a distance to an object within the environment at the height of the proximity sensor on the autonomous vehicle. An operation of the autonomous vehicle can be controlled based on the signal indicative of the distance to the object.Type: ApplicationFiled: March 9, 2018Publication date: May 6, 2021Inventors: Stephen D.
