In this work, antennas utilized for an intra-vehicle 3-11 GHz and 55-65 GHz channel measurement are described. A measurement antenna should not only provide a wide-band impedance bandwidth but also have a stable radiation pattern and a high fidelity factor. For the lower frequency band, a metal conical monopole antenna is proposed for its frequency stable H-plane omnidirectional radiation pattern. ...

  • Tendon-Driven Variable Impedance Control Using Reinforcement Learning

    Biological motor control is capable of learning complex movements containing contact transitions and unknown force requirements while adapting the impedance of the system. In this work, we seek to achieve robotic mimicry of this compliance, employing stiffness only when it is necessary for task completion. We use path integral reinforcement learning which has been successfully applied on torque-driven systems to learn episodic tasks without using explicit models. Applying this method to tendon-driven systems is challenging because of the increase in dimensionality, the intrinsic nonlinearities of such systems, and the increased effect of external dynamics on the lighter tendon-driven end effectors. We demonstrate the simultaneous learning of feedback gains and desired tendon trajectories in a dynamically complex sliding-switch task with a tendon-driven robotic hand. The learned controls look noisy but nonetheless result in smooth and expert task performance. We show discovery of dynamic strategies not explored in a demonstration, and that the learned strategy is useful for understanding difficult-to-model plant characteristics.
