    Abstract: A synchronous high speed motion stop for a series of multi-top loaders residing on “n” controllers on one rail achieves effective detection of the servo-error status and shut off of the trailing controller's servo power within 3 ITP time. The control method reduces the unnecessary error recovery because it only shuts off its immediate trailing controller without aborting its leading controller, allowing the leading controller to complete the cycle tasks. The cascade control method produces a synchronous high-speed motion stop for the robots across the controllers and effectively prevents the collision between the robots.

    Abstract: Disclosed herein are a path planning apparatus and a method for a robot to plan an optimal path along which a manipulator of a robot moves to a goal point from a start point. An obstacle within a prescribed angle on a straight line connecting a start point and a goal point is recognized as a middle point in a configuration space and arbitrary points separated from the middle point by a prescribed distance are selected. Among the selected points, arbitrary points which can directly connect the start point and the goal point without passing the obstacle are selected as waypoints to map a new middle node. A path is extended via the middle node and extension of a tree in a wrong direction is minimized so that the manipulator is not struck at local minima without depending greatly on a goal score, thereby improving the performance of path planning and rapidly searching for a path.

  • Publication number: 20110035052
    Abstract: The present invention features methods for operating, such as methods for dispersing and clustering, robotic devices (i.e., “robots”) that employ adaptive behavior relative to neighboring robots and external (e.g., environmental) conditions. Each robot is capable of receiving, processing, and acting on one or more multi-device primitive commands that describe a task the robot will perform in response to other robots and the external conditions. The commands facilitate a distributed command and control structure, relieving a central apparatus or operator from the need to monitor the progress of each robot. This virtually eliminates the corresponding constraint on the maximum number of robots that can be deployed to perform a task (e.g., data collection, mapping, searching, dispersion, and retrieval). By increasing the number of robots, the efficiency in completing the task is also increased.

    Abstract: A robotic crash protector device is configured for heavy payload applications. The device includes a housing, a piston and an actuator movably mounted within the housing, a cam member secured within the housing in fixed relation to the housing's base, and a switch. The cam member includes a cam surface with some portions being closer to the housing's base than other portions. The actuator includes bearing members that are configured to, responsive to a rotational force imparted to the actuator, move along the cam surface and thereby collectively displace the piston. The switch detects this displacement and indicates a crash. When moving along the cam surface, the bearing members are each configured to engage the surface along a line of contact, rather than at a single point. With forces imparted to each bearing member and the cam surface distributed across a line, the components better endure heavy payload applications.

    Abstract: A medical robotic system comprises a number of components that may be monitored to determine their preventive maintenance needs by recording usage-related information for the monitored components into associated non-volatile memories. When usage of the component exceeds a specified usage threshold, the system displays a warning message on its display screen to have preventive maintenance performed for the component. If the usage continues without such maintenance and exceeds a higher usage threshold, the system displays an error message on its display screen and the system transitions into an error state during which medical procedures are not allowed to be performed. The usage-related information may also be communicated to a remote computer which gathers and processes usage-related information from a number of medical robotic systems to estimate resource requirements for timely performing preventive maintenance on the medical robotic systems, and anticipated service revenues from such maintenance.

  • Publication number: 20100198402
    Abstract: Methods, devices (such as computer readable media), and systems (such as computer systems) for performing movements of a tool of a medical robot along a single axis that are achieved by electronically limiting the medical robot's movement to produce movement of the tool along the single axis rather than mechanically restricting the medical robot's movement to produce the single axis movement. The tool's movement will be along the single axis even if a user is moving an input device linked to the medical robot in other axes during the single axis movement. In addition, techniques are disclosed for automating the single axis movement such that it can be programmed to stop at a target location and start at or near a second (e.g.

  • Patent number: 7765031
    Abstract: In a robot, a first determining unit determines whether there is an interference region in which a first occupation region and a second occupation region are at least partially overlapped with each other. A second determining determines whether a second movable part of another robot is at least partially located in the interference region based on an actual position of the second movable part. A stopping unit begins stopping, at a predetermined timing, movement of the first movable part if it is determined that there is the interference region, and that the second movable part is at least partially located in the interference region. The predetermined timing is determined based on a positional relationship between an actual position of the first movable part and the interference region.
