    Abstract: A system and method for controlling tendon-driven manipulators that provide a closed-loop control of joint torques or joint impedances without inducing dynamic coupling between joints. The method includes calculating tendon reference positions or motor commands by projecting a torque error into tendon position space using a single linear operation. The method calculates this torque error using sensed tendon tensions and a reference torque and internal tension. The method can be used to control joint impedance by calculating the reference torque based on a joint position error. The method limits minimum and maximum tendon tensions by projecting the torque error into the tendon tension space and then projecting ii back into joint space.

A substrate transfer apparatus according to the present invention includes a multijoint arm whose one end is arranged on a base and the other end is connected to a hand for supporting a substrate, a linear guide for guiding a rectilinear movement of the hand, and a belt driving mechanism for moving the hand along a guide rail of the linear guide. The substrate transfer apparatus having such a configuration supports a load acting on the hand by the multijoint arm and ensures rectilinear transfer performance of the hand by the linear guide. Therefore, since a special mechanism for passing the substrate through a dead point is not required, the configuration is prevented from becoming complicated. Furthermore, since the load does not directly act on the linear guide, high transfer accuracy can be obtained.

  • Publication number: 20100101346
    Abstract: In one embodiment, a robotic manipulator arm includes a robotic joint, a rotational position sensor, and a control system. The rotational position sensor is coupled to the main housing of the robotic joint. The control system is connected to the rotational position sensor. During normal rotational motion toward a commanded motor position of joint output, the control system determines that normal joint un-slipped motion is occurring with respect to the joint output in response to the motor input commands. Responsive to joint slip during commanded motor motion, the control system compares position data from the rotational position sensor to commanded motor position to generate an error value and, based on the error value, compensates for the joint slip.

    Abstract: A method for estimating joint load at a joint of a segment. The method comprises the steps of receiving kinematic data, determining a modified acceleration using at least the kinematic data, estimating a joint load using at least the modified acceleration; and determining simulated kinematic data for the segment using at least the joint load. The present disclosure thus addresses the problems with conventional inverse dynamics analysis by providing a forward dynamics solution for estimation of joint loads that is stable, guaranteed to converge, computationally efficient, and does not require acceleration computations. According to one embodiment, a joint load is estimated using an approach of closed form dynamics.

  • Patent number: 7610108
    Abstract: A method for providing independent static and dynamic models in a prediction, control and optimization environment utilizes an independent static model (20) and an independent dynamic model (22). The static model (20) is a rigorous predictive model that is trained over a wide range of data, whereas the dynamic model (22) is trained over a narrow range of data. The gain K of the static model (20) is utilized to scale the gain k of the dynamic model (22). The forced dynamic portion of the model (22) referred to as the bi variables are scaled by the ratio of the gains K and k. The bi have a direct effect on the gain of a dynamic model (22). This is facilitated by a coefficient modification block (40). Thereafter, the difference between the new value input to the static model (20) and the prior steady-state value is utilized as an input to the dynamic model (22). The predicted dynamic output is then summed with the previous steady-state value to provide a predicted value Y.
