Abstract

A mobility apparatus (10) includes a position acquiring unit (3) that acquires a current position using a satellite; a control unit (1) that controls wheels (7a, 7b) along a route based on the acquired current position; and number-of-revolutions measuring units (8a, 8b) that measure numbers of revolutions of the wheels (7a, 7b). If acquiring the current position using the satellite is disabled, the control unit (1) calculates distances per revolution of the wheels (7a, 7b) from a moving distance by using the satellite and the numbers of revolutions of the wheels (7a, 7b) measured during the period in which the mobility apparatus has moved by the moving distance, calculates numbers of revolutions of the wheels (7a, 7b) at a distance by which the mobility apparatus is to move after acquiring the current position is disabled, and causes the wheels (7a, 7b) to rotate by the calculated numbers of revolutions.
