Abstract: An action of a robot included in a robot system is controlled based on a learning result of a machine learning device. The machine learning device includes a behavior observing unit, a displaced amount observing unit, and a learning unit. The behavior observing unit observes a behavior pattern of the robot picking out a workpiece from a container. The displaced amount observing unit observes, based on pieces of image data captured before and after the pick-out action of the robot and output from an image capturing device, a workpiece displaced amount indicating a displaced amount of an untargeted workpiece in the container caused by picking out a targeted workpiece from the container. The learning unit learns an influence rate on the untargeted workpiece with an associated behavior pattern of the robot for picking out the targeted workpiece from the container, the influence rate depending on the workpiece displaced amount.

Abstract: A starting point, a set of one or more way points, and a destination point of a route along which the ADV is to be driven are determined. All lane segments near the starting point, the set of way points, and the destination point within a predetermined threshold distance are determined respectively. A set of route candidates are determined with an A-star (A*) searching algorithm based on a set of nodes representing all the lane segments near the starting point, the set of way points, and the destination point respectively. The route is selected from the set of route candidates based on respective costs of the set of route candidates. The ADV is being controlled to drive along the selected route autonomously.

Abstract: A robot motion planning technique for component assembly operations. Inputs to the motion planning technique include geometric models of the components being assembled, and initial and target configurations. The method begins at a tightly-constrained target or final configuration and plans in the direction of a loosely-constrained initial configuration. A randomly-sampled waypoint configuration is proposed, followed by a local search for feasible configurations which generates nodes that extend a path toward the initial configuration while sliding through the tightly-constrained region. The local search can be repeated multiple times for a given randomly-sampled configuration. When a completed path is found, the action sequence is trimmed to eliminate unnecessary extraneous motions in the loosely-constrained region. The disclosed method dramatically reduces the number of unproductive configurations evaluated and finds assembly solutions much faster in comparison to known tree-based motion planning methods.

Abstract: A control system controls an operation mode of a mobile robot that autonomously moves in a predetermined area, and includes a feature detection unit, a classifying unit, and a system controller. The feature detection unit detects features of a person who is present in the vicinity of the mobile robot. The classifying unit classifies the person into a predetermined first group or a predetermined second group based on the features. The system controller selects a first operation mode when the person who belongs to the first group is present in the vicinity of the mobile robot and selects a second operation mode that is different from the first operation mode when the person who belongs to the first group is not present in the vicinity of the mobile robot, thereby controlling the mobile robot.

Abstract: An assembly for closure of an opening into a vessel, has a valve chamber, a valve biased toward a closed position in which the valve closes the first opening, and a retainer that retains the valve in an open position. A flow of cryogen from a first opening through the valve chamber to a second opening acts to displace the retainer and allow the valve to close.

Abstract: Servo-valve that drives an actuator by using a fluid. The servo-valve includes a nozzle having a discharge edge forming an outline of a discharge port from which the fluid is discharged and a tapered inner wall growing narrower toward the discharge edge, and a receiver that is provided with a flow path into which the fluid discharged from the discharge port flows. The nozzle is displaced in a direction different from the fluid discharge direction. The flow path extension direction is inclined with respect to a direction orthogonal to an inflow surface facing the nozzle by an angle ?. A taper angle determined by the tapered inner wall is larger than twice the angle ?. With such a configuration, the component of flow force exerted from the fluid on the tapered inner wall decreases. Since the nozzle can be quickly displaced, response speed of the actuator is improved.

Abstract: High-pressure cryogenic fluid conduits that deliver high-pressure cryogenic fluids from a first point to a second point. This high-pressure fluid conduit has a safety feature that is activated when the high-pressure cryogenic fluid conduit fails due to exposure to a predetermined force. The safety feature is activated by the fracture of an annular ring that is positioned at either end of the high-pressure fluid conduit and is calibrated to fracture when exposed to the predetermined force. Fracture of the annular ring closes valves at each end of the high-pressure fluid conduit, thereby stopping the flow of high-pressure fluid from the high-pressure fluid source as well as the escape of high-pressure fluid from the high-pressure fluid container.
