Patent attributes
An example autonomous device is configured to move within a space. The autonomous device includes a first system to detect a first location of the autonomous device within the space, with the first location being based on a first fixed reference; a second system to detect a second location of the autonomous device within the space, with the second location being based on a second fixed reference; and a third system to detect a third location of the autonomous device within the space based on relative movements of the autonomous device. One or more processing devices are configured to select one of the first location or the second location based on reliability of at least one of the first location or the second location, and to control movement of the autonomous device using an estimated location that is based on the third location and the selected one of the first location or the second location.
