Zusammenfassung:PROBLEM TO BE SOLVED: To provide a movable-body driving device capable of driving a movable body in an appropriate state in accordance with a change in drive resistance of the movable body.SOLUTION: A movable-body drive device 200 driving a movable body with the power of a motor includes a control section 101 for estimating drive resistance of the movable body using a current value flowing when applying a predetermined voltage to the motor or a voltage value generated when applying a predetermined current to the motor, selecting a power supply correction value based on the drive resistance, and adjusting a value of power supply to the motor based on the power supply correction value so as to cancel a change in the drive resistance of the movable body.
