    摘要: A pump control device and a valve control device each includes: an instruction calculator that calculates a control instruction of causing a controlled object to operate by using a manipulation amount of a manipulation and at least one control parameter, and inputs the calculated control instruction to the controlled object; and an ideal output calculator that calculates an ideal output of an actuator, the ideal output being associated with the manipulation amount of the manipulation. The pump control device adjusts at least one pump control parameter to reduce a difference between a control output and the ideal output when an operation of a movable part is a power running operation. The valve control device adjusts at least one valve control parameter to reduce a difference between a control output and the ideal output when the operation of the movable part is a non-power running operation.

    摘要: An automatic operating device includes: a position estimation part that includes an interaction model, and calculates, as estimative position data, actual position data corresponding to force data which is input; a force computation part that includes a force computation model, calculates force data corresponding to a deviation which is input, and inputs the force data to the position estimation part; a database that stores a base parameter that is a parameter having been calculated in past; and a parameter setting part that calculates, on the basis of the base parameter, a target parameter corresponding to each of a norm y(t) of an actual position and a norm u(t) of a force, and sets the target parameter to a parameter of each of the interaction model and the force computation model.

    摘要: A measurement device is configured to: calculate first contour data of a container in an empty state at a first time; calculate second contour data indicating a surface contour of an object at a second time in execution of a scooping operation by the container; rotate the second contour data, based on differential information indicating a difference between second posture data of a working gear 4 at the second time and first posture data of the working gear 4 at the first time; specify a region defined by supplemental contour data for supplementing the surface contour of the object contained in the container in the execution of the scooping operation, the rotated second contour data, and the first contour data; and calculate, based on the specified region, a first volume indicating a volume of the object contained in the container.

    摘要: A remote operation device and a remote operation system that can reduce or eliminate deviation of the position of an indicator image of a working unit such as a line image in an image with respect to the position of the working unit in a real space. In some case, because of a cause such as a communication failure, a position posture coordinate value of a working unit corresponding to captured image data in a work environment image deviates from a position posture coordinate value of the working unit estimated according to an operation form of a remote operation mechanism. In this case, a semitransparent indicator image Img2(τ2) simulating a bucket is superimposed on a work environment image Img1(τ2) in a position where the bucket is estimated to be originally present and deviating from an image region representing the bucket.

    摘要: A method for treating or repairing osteochondral damage in a subject in need thereof, including administering to the subject a cell preparation comprising pluripotent stem cells positive for SSEA-3 isolated from a body mesenchymal tissue or cultured mesenchymal cells. The pluripotent stem cells have all of the following properties: (i) CD105-positivity; (ii) low or absent telomerase activity; (iii) having ability to differentiate into any of three germ layers; (iv) absence of demonstration of neoplastic proliferation; and (v) self-renewal ability. The pluripotent stem cells are administered at 1×103 cells to 2×107 cells as individual.
