1. A travel device, comprising:
- a plurality of wheels disposed in parallel;
a step plate mounted between the plurality of wheels for a driver to place feet;
a handle mounted vertically to the step plate;
a vehicle body between the plurality of wheels, the vehicle body supporting the step plate;
a driving motor to allow the step plate and/or the handle to tilt in a roll axis direction, and to drive at least one of the step plate and the handle to tilt in the roll axis direction; and
a control unit to control the driving motor to maintain at least one of a horizontal position of the step plate and a vertical position of the handle; and
a measurement unit to measure a shift operation of at least one of the step plate and the handle from a neutral position in at least one of a horizontal state of the step plate and a vertical state of the handle maintained by the driving motor,wherein the plurality of wheels change a traveling direction according to a value measured by the measurement unit,wherein the step plate and/or the handle are able to tilt in a roll axis direction with respect to the vehicle body,wherein the handle and the step plate are coupled to each other by a link mechanism that maintains a perpendicular relationship between the handle and the step plate, andwherein the driving motor drives the handle to tilt in the roll axis direction, and the step plate is thereby controlled through the link mechanism.

Abstract
A travel device includes a plurality of wheels disposed parallel to one another, a step plate mounted between the wheels, a handle mounted to the step plate, and a driving motor that allows the step plate and handle to tilt in a roll axis direction. The device further includes a control unit that drives the motor so as to maintain the step plate horizontal or the handle vertical. The device also includes a measurement unit that measures a shift operation of the step plate or the handle. The plurality of wheels may change direction based on the value determined by the measuring unit.
