N number of fingers are moved by a first drive part so that a circumcircle of a N-sided polygon constituted by the fingers is arranged in a concentric pattern about the center axis of the object. Each first roller is rotatable about an axis parallel to the center axis of the object, and is configured to contact the inner peripheral portion of the object by movement of the finger relative to a hand base. By rotationally driving at least one first roller while a radially outward force is applied to the object, the object may be rotated relative to the hand base.

    Abstract: An actuator having a two-parameters energy converter is coupled to a transducer and is driven by a controller. Prior to assembly and operation of the actuator, a calibration procedure is performed. The calibration procedure, together with the unique controller, enable accurate control of the output parameters of the actuator. In one example, the parameters are rate and force, and the calibration and controller enable accurate control of the rate and force at the output of the actuator by measuring only the rate at the output of the energy converter. Consequently, no sensors are needed at the output of the actuator, i.e., at the output of the transducer, where the load is applied.

  • Publication number: 20100171332
    Abstract: An electrical gripper has a housing and a solenoid plunger. A pair of jaws are movably mounted with the housing. The jaws are movable towards and away from each other. The jaws are coupled with the solenoid plunger to provide movement to the jaws. A first mechanism is associated with the solenoid plunger to lock the solenoid plunger in a first position when power is terminated to the solenoid plunger. A second mechanism is associated with the solenoid plunger to lock the solenoid plunger in a second position when power is terminated to the solenoid plunger. Thus, the jaws are actively locked in an open or close position when power is terminated to the solenoid plunger.

  • Patent number: 7670555
    Abstract: A parallel gripper for handling multiwell plates in an automated analysis system, moves individual multiwell plates between a plate storage array unit (i.e., plate hotel) and an imaging station. More particularly, the gripper has two parallel plate-gripping arms that move in equal, but opposite linear directions and are controlled using a stepper motor. Each of the arms has a shelf that provides support for the corresponding side edge of a multiwell plate.

  • Publication number: 20080277953
    Abstract: An end effector for use on a robotic arm includes a clamping assembly for clamping a workpiece, and a tool such as a drill for performing an operation on the clamped workpiece. The clamping assembly is slidably mounted on the robotic arm and self adjusts its position relative to the workpiece before a clamping operation is performed. Linear actuators independently control the movements of the clamping members. The actuators are operated by a controller, based in part on position information produced by sensors that sense the position of the clamping members.

  • Publication number: 20080039973
    Abstract: First of all, in a first step S1, each actuator command value for position command value and posture command value of an end-effector is determined. Next, in a second step S2, rotational resistance values of a first and a second universal joints are obtained, and in a third step S3, the force and the moment exerted to each of the second universal joints are computed using this, and in a fourth step S4, the resultant force and the resultant moment exerted to the end-effector are determined from these. Then, in the fifth step, the elastic deformation amount of a mechanism is computed using these, and a compensation amount of the actuator command value is computed using these values. And then, in the sixth step, the actuator command values determined in the first step are updated with the compensation amount determined in the fifth step taken into account.
