Abstract: A ball-balancing robot is capable of accurately controlling its posture when a robot main body is rotated about the vertical axis in a yaw direction in a state in which the robot main body is positioned on a spherical object in a posture in which a gravity center of the robot main body matches a vertical axis passing a center of the spherical object, and in a state in which a base axis of the roll-direction angular velocity sensor is inclined with respect to the horizon in a pitch direction (at an inclination angle θP), the robot main body is able to rotate while maintaining a predetermined posture by making correction to cancel a detection error in the angular velocity in the roll direction generated based on the inclination of the base axis of the roll-direction angular velocity sensor.

Abstract: A tire angular velocity controller (211) is input with a difference between a target value of a rotational angular velocity of 0 for main wheels (11) and a rotational angular velocity of the main wheels (11), which is a differential value of a signal output from a main wheels rotary encoder (26). The tire angular velocity controller (211) calculates an inclination angle for the main body (10) that will cause the difference to become zero. In a second control mode, the calculated inclination angle is used as a target inclination angle and the difference between this target inclination angle and the inclination angle of the main body (10) at the present time input from an inclination angle sensor (20) is input to a main body inclination angle controller (212).

Abstract: A pushcart in which a user can adjust a balance direction based on his/her own sense even on a slope. The pushcart includes a pair of wheels, driving units, a pair of wheels are supported on a main body unit in a rotatable manner, a grip portion provided on another side of the main body unit, and a support portion that is connected to the main body unit on one side so as to be capable of rotating in a pitch direction and supports assist wheels in a rotatable manner on another side. An angle formed between the main body unit and a direction orthogonal to the ground surface is estimated based on detected angle between the main body and the support portion. An attitude of the main body unit in the pitch direction is controlled based on a target pitch angle corrected using a correction value.

Abstract: A support unit is connected to a shaft of a main wheel and thus is always maintained in parallel to or at a predetermined angle to a road surface, independently of an inclination angle of a main body. Accordingly, an incline estimating unit regards an inclination angle θ3 being a value in an inclination sensor as being equal to an inclination angle θ2 of the road surface (or in a case where the support unit is inclined a predetermined angle to the road surface, an angle from θ3 to the predetermined angle is subtracted from or added to the crossing angle) and outputs the estimated inclination angle θ2 of the road surface to a target inclination angle determining unit.
Abstract translation: 支撑单元连接到主轮的轴，因此总是与主体的倾斜角度保持平行或与路面成预定的角度。 因此，倾斜估计单元将倾斜传感器中的值的倾斜角θ3与路面的倾斜角θ2相等（或者在支撑单元相对于路面倾斜预定角度的情况下， 从θ3到预定角度的角度从交叉角度减去或相加），并将估计的路面倾斜角θ2输出到目标倾斜角确定单元。
