Abstract
A moving device includes: two leg portions each including an end-portion wheel and an intermediate wheel; a placement portion supported by the two leg portions; and a control unit configured to control the two leg portions. The moving device is configured such that, under a state of four-wheel ground contact in which the end-portion wheel and the intermediate wheel are in contact with the ground, when the end-portion wheel is moved from the boarding area to the step of the escalator and/or when the end-portion wheel is moved from the step to the landing area of the escalator, a wheel speed of the end-portion wheel is controlled by the control unit.
Claims11
A moving device for moving a moving object while having the moving object loaded thereon, the moving device comprising:
- two leg portions each including an end-portion wheel and an intermediate wheel;
- a placement portion supported by the two leg portions;
- and
- a control unit configured to control the two leg portions,
- wherein, under a state of four-wheel ground contact in which both of the end-portion wheels that are rear wheels and both of the intermediate wheels that are front wheels are in contact with a ground, when the end-portion wheel is moved from a boarding area to a step of an escalator and/or when the end-portion wheel is moved from the step to a landing area of the escalator, a wheel speed of both of the end-portion wheels that are rear wheels is controlled by the control unit,
- wherein the control unit is configured to acquire coordinate values obtained when the intermediate wheel is moved from the boarding area to the step or when the intermediate wheel is moved from the step to the landing area, and to control the wheel speed of the end-portion wheel when the end-portion wheel arrives at a position identified by the coordinate values.
A moving device for moving a moving object while having the moving object loaded thereon, the moving device comprising:
- two leg portions each including an end-portion wheel and an intermediate wheel;
- a placement portion supported by the two leg portions;
- a control unit configured to control the two leg portions;
- and
- an end-portion wheel actuation configured to drive the end-portion wheel,
- wherein, under a state of two-wheel ground contact in which both of the end-portion wheels are in contact with a ground, when the end-portion wheel is moved from a boarding area to a step of an escalator and/or when the end-portion wheel is moved from the step to a landing area of the escalator, a translational speed of the moving device is controlled by the control unit,
- wherein the control unit is configured to (a) control the end-portion wheel actuator so that, when the end-portion wheel is moved from the boarding area to the step, the translational speed of the moving device becomes equal to a forward translational speed of the step, and/or (b) control drive torque of both end-portion wheels so that, when the end-portion wheel is moved from the step to the landing area, the translational speed of the moving device is equal on the step and after exiting to the landing area.
