    摘要: A robotic system includes a robot having manipulators for grasping an object using one of a plurality of grasp types during a primary task, and a controller. The controller controls the manipulators during the primary task using a multiple-task control hierarchy, and automatically parameterizes the internal forces of the system for each grasp type in response to an input signal. The primary task is defined at an object-level of control, e.g., using a closed-chain transformation, such that only select degrees of freedom are commanded for the object. A control system for the robotic system has a host machine and algorithm for controlling the manipulators using the above hierarchy. A method for controlling the system includes receiving and processing the input signal using the host machine, including defining the primary task at the object-level of control, e.g., using a closed-chain definition, and parameterizing the internal forces for each of grasp type.

    摘要: A robotic system includes a dexterous robot having robotic joints, angle sensors adapted for measuring joint angles at a corresponding one of the joints, load cells for measuring a set of strain values imparted to a corresponding one of the load cells during a predetermined pose of the robot, and a host machine. The host machine is electrically connected to the load cells and angle sensors, and receives the joint angle values and strain values during the predetermined pose. The robot presses together mating pairs of load cells to form the poses. The host machine executes an algorithm to process the joint angles and strain values, and from the set of all calibration matrices that minimize error in force balance equations, selects the set of calibration matrices that is closest in a value to a pre-specified value. A method for calibrating the load cells via the algorithm is also provided.

    摘要: A system and method for providing multiple priority impedance control for a robot manipulator where impedance laws are realized simultaneously and with a given order of priority. The method includes a control scheme for realizing a Cartesian space impedance objective as a first priority while also realizing a joint space impedance objective as a second priority. The method also includes a control scheme for realizing two Cartesian space impedance objectives with different levels of priority. The method includes instances of the control schemes that use feedback from force sensors mounted at an end-effector and other instances of the control schemes that do not use this feedback.

    摘要: A technique that determines the tension in a tendon using a conduit reaction force applied to an end of a conduit through which the tendon is threaded. Any suitable tendon tension sensor can be employed that uses the conduit reaction force for this purpose. In one non-limiting embodiment, the tendon tension sensor includes a cylindrical strain gauge element and a force member mounted to an end of the conduit. The force member includes a cylindrical portion having a bore and a plate portion, where the cylindrical portion is inserted into a bore in the strain gauge element. The tendon is threaded through the strain gauge element and the force member. A strain gauge is mounted to the strain gauge element and measures the reaction force when tension on the tendon causes the strain gauge element to be pushed against the force member.

    摘要: Disclosed is drive apparatus especially useful for controllably displacing the carrier of a printer, the drive apparatus including a lead screw having laterally spaced apart and floating threaded followers thereon. Intermediate the threaded followers are a first pair of preloaded springs which press the followers against the opposite flanks of the threads on the lead screw to thereby inhibit backlash intermediate the followers. A second pair of springs are mounted intermediate a bracket, which is fastened to the carrier, and at least one of the followers for effecting coupling between the carrier and the follower while controlling backlash therebetween. A pair of arms extend from the followers and are coupled to a restraining shaft in such a manner as to inhibit rotational movement of the arms (and thus the followers) while permitting motion of the followers in any perpendicular direction to the lead screw to accommodate runout or eccentricity.

    摘要: An error detection vision system that determines whether a proper part has been selected from a presentation device during an assembly process. In one embodiment, the presentation device is a rack including a plurality of bins, where the bins hold a plurality of different parts. The vision system includes one or more projecting devices that project a light beam towards the presentation device and a detector, such as a camera, receiving reflections back from a worker as he selects parts from the presentation device. The error detection vision system can employ various detection processes, such as a stereo pair of video cameras, vision using structured-light triangulation and infrared time-of-flight distance measurements.
