  • Publication number: 20130282237
    Abstract: An inverted pendulum type moving body has a pair of wheels suspended by a main body of the moving body and arranged in the same plane perpendicular to a direction in which the moving body moves on a floor surface as a traveling surface; a driving mechanism that rotates the wheels; and a driving controller that controls the driving mechanism and thereby maintains an inverted state of a moving robot body. The inverted pendulum type moving body includes a wheel rotational speed measurer that measures rotational speeds of the wheels; a main body front-back direction angular velocity measurer that measures an inclination angular velocity of the main body of the moving body in a front-back direction; suspension actuators that move the wheels in a vertical direction; and a suspension actuator driving unit that drives the suspension actuators.

  • Publication number: 20110137462
    Abstract: This mobile unit suppresses lateral vibration produced when the mobile unit passes over a step. A stabilizer according to the present invention predicts contact timing at which the mobile unit makes contact with a step, which may be a bump or pit, using sensor information or map information, shifts the center of gravity of the mobile unit laterally by controlling actuators, and shits the center of gravity laterally for the next step after detecting that the mobile unit has passed over the previous step.

  • Publication number: 20110073603
    Abstract: The storage case has a structure in which a sample storage case (S) contained in a storage case is cooled and held at a low temperature by a Stirling refrigerator. A detection element is disposed in a room-temperature area of the storage case. The chemical or physical property of the detection element varies when a contaminant adheres to the detection element. Entrance of a contaminant into the storage case can be checked by contactlessly checking the detection element from the outside of the storage case. The storage case includes a server for receiving the result of the check from the detection device, storing the result, and setting up connection via a communication line to at least two out of a terminal operable by the forwarder, a terminal operable by the carrier, and a terminal operable by the recipient to transmit the result to the two.

  • Publication number: 20110054681
    Abstract: A robot, having left and right leg portions on a lower portion of a body, each of the legs has a wheel attached at a tip of the leg portion, to be drivable, a suspension having a spring and a dumper attached in parallel, between the wheel and the body, and an actuator attached between the suspension and the body. The suspension and the actuator are connected in series, and an inclination detecting means mounted on the body detects an inclination angle and an angular velocity of the robot with respect to a direction of gravity. A control instruction value outputting means controls the actuator upon basis of information thereof, so that the robot travels along a target angle and a target angular velocity thereof. The, spring is connected with an actuator expanding and constructing up and down, in series.
