Provided is an autonomous wheeled device. A first sensor obtains first data indicative of distances to objects within an environment of the autonomous wheeled device and a second sensor obtains second data indicative of movement of the autonomous wheeled device. A processor generates at least a portion of a map of the environment using at least one of the first data and the second data and a first path of the autonomous wheeled device. The processor transmits first information to an application of a communication device paired with the autonomous wheeled device and receives second information from the application.
