Abstract
A device that supports a motion for restoring an inclination angle of a body to a reference direction is provided. A balance device includes a sensor, at least one flywheel, and a controller. The sensor is configured to detect an inclination angle of the body with respect to the reference direction. The at least one flywheel is arranged on the balance device so that an axis of the flywheel is non-parallel to a yaw axis of the body when the balance device is attached to a user. The yaw axis of the body corresponds to a longitudinal direction of the body. In addition, the yaw axis coincides with the reference direction when the user stands erect. The controller is configured to change a rotation rate of the flywheel based on an inclination angle detected by the sensor.
