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

PROBLEM TO BE SOLVED: To provide a traveling type moving body capable of sufficiently eliminating dirt from its wheel, and its control method. SOLUTION: The traveling type moving body has the wheel 2 which advances in a first direction when rotating normally and advances in a second direction when rotating reversely and a brush 3 disposed in the vicinity of the wheel 2. The traveling type moving body also has a control section 5 which brings the brush 3 into contact with the wheel 2 on the side of the second direction of the wheel 2 during its normal rotation and keeps the brush 3 away from the wheel 2 during its reverse rotation.

PROBLEM TO BE SOLVED: To provide a neuronal apparatus and the like suitable for performing appropriate control by making a neuron threshold variable, extending Hebb's rule, and devising integer expressions, in a neuronal network. SOLUTION: In the neuronal apparatus 101 for simulating nerve cells, a threshold storage part 102 stores a threshold variable θ and two threshold coefficients Δθ1 and Δθ2, an input reception part 103 receives one or more input of input signal values at prescribed time intervals, an output part 104 outputs as an output signal value 1 assuming that the neural apparatus 101 is igniting when a total sum s of input signal values is threshold variable θ or larger and 0 assuming that the neural apparatus 101 is at rest otherwise; and a threshold update part 105 calculates Δθ1X + Δθ2(X-1) from an outputted output signal value X and the stored threshold coefficients Δθ1 and Δθ2 and updates the value of the threshold variable θ to be stored by the threshold storage part so that it increases just by the result of calculation.

PROBLEM TO BE SOLVED: To accomplish a leg type robot capable of securing a large stride while the robot body is suppressed in a low position without increasing the moment acting on a roll joint of the rising leg when the robot is in the upright attitude by a single leg owing to the gravitational force acting on the robot body. SOLUTION: The leg type robot 100 is structured so that a pair of legs 20 are coupled with the robot body 10 on the body side face 12 rotatably round the pitch axis (Y-axis), which enables increasing the height H1 of the legs while the robot body 10 is suppressed in a low position. Thereby a large stride can be secured while the robot body 10 is suppressed in low position. The structure of the legs 20 is such that the roll joints 38 and 42 are positioned below the body undersurface 14. This suppresses an increase of the distance L1 in the pitch axis direction between the rotary shaft C1 of each joint and the center of gravity G of the robot body. The moment acting on the roll joint of the rising leg when the robot is in the upright attitude by single leg, remains out of increase. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To control the reaction force of an operation element so that an object easily follows a target track without previously storing the target track. SOLUTION: A movement mechanism 11 of a work assist apparatus 10 has a coating tool 30 and the operation element 18. A work additionally carries out a translation operation and a rotation operation when the operation element 18 directs a moving position of a control point P moved by the movement mechanism 11. A controller 22 controls an actuator group 16 of the movement mechanism 11 so that the reaction force to the translation operation which is increased with the increase of an angle made between the direction of a reference line (x-axis) fixed to the operation element 18 and the direction of translation operation is applied on the operation element 18. The coating tool 30 is rotated around the reference point P fixed to the coating tool 30 corresponding to the rotation operation. As a result, the reference point P is easily moved along the target track while the x-axis direction of the coating tool 30 is agreed with the direction of the target track L.
