Abstract: 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.

Abstract: A robotic device is used to generate a map of a facility. A processor will receive a facility description that includes an initial path and one or both of the following: a first number of navigable openings that are positioned along the initial path, or a first number of barriers that are positioned along the initial path. The robotic device will move along the initial path. As this happens, one or more sensors of the robotic device will capture a data set of sensed characteristics of the facility. The processor will analyze the data set to detect navigable openings along the initial path, and it will assign an identifier to each navigable opening. The processor will use the identifiers of the navigable openings to develop a map of the facility that includes the navigable openings. The processor will save the map to a data store.

Abstract: A robotic device including a plurality of light emitting modules and a processor is disclosed. The processor is configured to identify one or more machine states of the robotic device and a status of each of the one or more machine states, select at least one of the one or more machine states, determine a visual pattern corresponding to a status of the at least one selected machine state, cause the plurality of light emitting modules to output the visual pattern. The one or more machine states include one or more of the following: a navigation state, a sensor function state, a collision alert state, or an error state.
