Title: ELECTRIC VACUUM CLEANER
Abstract:
Provided is an electric vacuum cleaner (11) that can achieve efficient cleaning by the improvement in map producing accuracy. The electric vacuum cleaner (11) includes a body case, a driving wheel, a camera (51), a distance calculating unit (63), a self-position estimating unit (65), a mapping unit (66), and a control unit (26). The driving wheel allows the body case to travel. The camera (51) is provided in the body case and takes images on the traveling direction side of the body case. The distance calculating unit (63) calculates the distance to an object located on the traveling direction side on the basis of the images taken by the camera (51). The self-position estimating unit (65) calculates the location of the body case on the basis of the images taken by the camera (51). The mapping unit (66) produces a map of the three dimensional data with respect to the traveling location on the basis of calculation results from the distance calculating unit (63) and the self-position estimating unit (65). The control unit (26) controls the operation of the driving wheel on the basis of the three-dimensional data of the map produced by the mapping unit (66), whereby the body case autonomously travels.
