Abstract:
PROBLEM TO BE SOLVED: To reflect physical information (weight and a center of gravity position, etc.) on an occupant on a moving control of a moving body by a simpler method. SOLUTION: This inverted two-wheel type moving body 100 stores a physical information value specific to the occupant and is constituted to access to a memory card 231 portable by the occupant. The inverted two-wheel type moving body 100 reads the physical information value stored in the memory card 231 assigned to the actually boarding occupant from the memory card 231 and operates according to the read physical information value. By adopting this configuration, the physical information (weight and the center of gravity position, etc.) on the occupant can be reflected on the moving control of the moving body by a simpler method.

PROBLEM TO BE SOLVED: To provide a traveling device capable of executing consistent travel, and its control method. SOLUTION: A traveling device 10 includes a ground touching detection means to detect a ground touching state that a ground touching member touches a road surface, and a control means to perform inversion control by controlling the drive of a wheel. When the ground touching state of the ground touching member is detected by the ground touching detection means, the control means suspends the inversion control. Furthermore, when the start of braking is detected by the braking detection means and the ground touching state of the ground touching member is detected by the ground touching means, the control means may suspend the inversion control.

PROBLEM TO BE SOLVED: To provide a wheeled inverted pendulum mobile unit capable of stopping itself without shaking its body. SOLUTION: A mobile unit 100 includes support legs 20 downwardly extending from a body 10 and grounded at the front and behind of an axle 14 of driving wheels, with lower ends going up and down according to the inclination of the body 10, and a lock mechanism 26 fixing the position of the lower ends of the support members. The support legs 20 are grounded regardless of the operation/non-operation of an inverted pendulum control and move up and down according to the inclination of the body 10. Therefore, the support legs 20 do not interfere the inverted pendulum control though being grounded always. In the case of stopping the inverted pendulum control, the positions of the lower ends of the support legs 20 are fixed by operating the lock mechanism 26. When the inverted pendulum control shifts its state from operative to inoperative, the support legs 20 can support the body 10 without time lag. Thus, the body is not shaken by having the telescopic support legs 20 which is always grounded and the lock mechanism 26. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an inverted moving body and a movement stopping method of the inverted moving body, capable of stably stopping the moving body when an inverted state becomes unstable, in the moving body of moving by inversion control. SOLUTION: This inverted moving body has a rotary body having a cross section of a circular shape, a driving part for rotatingly driving the rotary body, a moving body main body for holding the rotary body, and a control part for controlling the driving part and maintaining an inverted state of the moving body main body by controlling rotational driving of the rotary body contacting with a floor surface. The moving body main body is constituted for holding the rotary body via a connecting member deformable so as to change a relative position in the vertical direction, and the control part is constituted so as to change the relative position in the vertical direction of the moving body main body and the rotary body by controlling deformation of the connecting member. When the control part cannot maintain the inverted state of the moving body main body, the moving body main body is relatively changed in a position vertically downward to the rotary body, and the moving body main body is contacted with the floor surface.

Abstract:
PROBLEM TO BE SOLVED: To provide an electromagnetic drive valve in which the mountability can be improved by preventing an armature stem from becoming longer in the axial direction owing to the incorporation of a lift sensor. SOLUTION: The armature stem 21 fixed with an armature 33 is coaxially arranged in a valve 11 functioning as a suction valve or an exhaust valve. An electromagnetic actuator 35 for closing drive is arranged around the armature stem 21, and the electromagnetic force actuates the armature 33 to open and close the valve 11 by displacing the armature stem 21 axially. The lift sensor 38 detects an amount of axial displacement in the armature stem 21 owing to the axial relative movement of a sensor coil 42 and a sensor core 46 accompanied by the displacement of the armature stem 21. In the armature stem 21, a recess 39 is installed in an opening at the upper end, and at least a part of each sensor coil 42 and sensor core 46 is arranged in the recess 39 respectively.
