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.

Robotic cleaning device with operating speed variation based on environment

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.

Safety module for a floor cleaning unit

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.

Long-range sonar

A long-range sonar assembly for detecting objects approximately 2.5-9.5 meters from a robotic device. The assembly includes a printed circuit board including a local controller operably connected to a processing device and configured to receive instructions from the processing device, a transmit potentiometer operably connected to the local controller and configured to produce a first transmit frequency, and a receive potentiometer operably connected to the local controller and configured to produce a first receive sensitivity; a transducer operably connected to the receive potentiometer; and a flared bell configured to house the transducer and the printed circuit board, the flared bell comprising at least a first enclosure for receiving a sub-assembly comprising the printed circuit board and the transducer.

A cleaning device may include a solution tank configured to store cleaning solution. The device delivers the cleaning solution from a pump discharge of the cleaning device to a flow meter. The device initiates a priming mode by opening a first valve associated with a bypass line of the device, closing a second valve associated with a cleaning head of the cleaning device, and delivering the cleaning solution from a discharge of the flow meter to the inlet of the solution tank through the bypass line. When the device is primed, it initiates cleaning by closing the first valve associated with the bypass line, opening the second valve associated with the cleaning head, and delivering the cleaning solution to the cleaning head.

Cleaning device with single tank recycling system

A cleaning device may include a solution tank configured to store cleaning solution. The solution tank may include an inlet and an outlet. The cleaning device may include at least one discharge line filter in fluid communication with the solution tank and a pump having a pump intake and a pump discharge. The pump may be configured to direct cleaning solution from the solution tank outlet through the at least one discharge line filter. The cleaning device may include a cleaning head in fluid communication with the pump discharge and a bypass line in fluid communication with the pump discharge and the inlet. The bypass line may be configured to divert cleaning solution received from the pump discharge away from the cleaning head and toward the solution tank.
