  • Patent number: 10745075
    Abstract: A traveling apparatus includes: an operation member configured to be displaced to a first range and a second range; an adjusting mechanism configured to adjust a wheel base length between a front wheel and a rear wheel in such a way that the wheel base length is increased when the user displaces the operation member in a direction away from a reference position in the first range; and a controller configured to control, when the user manipulates the operation member in the first range, a driving unit in such a way that the traveling apparatus travels forward based on a forward movement target speed that has been made to become larger as the wheel base length increases, in which the controller controls the driving unit in such a way that the traveling apparatus travels backward when the user manipulates the operation member in the second range.

  • Patent number: 10351202
    Abstract: In a traveling apparatus, a front wheel supporting member is coupled to a rear wheel supporting member rotatably around a pivot axis and with a support shaft in such a way that a wheel base length will become variable according to a relative posture of the front wheel supporting member and the rear wheel supporting member. Control is performed so that the greater the wheel base length, the greater a speed of the traveling apparatus in a forward direction will become. When the wheel base length is one at which the speed in the forward direction becomes substantially zero, while the front wheel is oriented in a straight traveling direction, an intersection point where the pivot axis crosses a road surface is located at a position offset from a grounding point where the front wheel is grounded on the road surface toward a side of the rear wheel.
