论文摘要
我们提出了一个本体感受的远程操作系统，该系统使用反身抓听算法来提高拾取任务的速度和稳健性。该系统由两个使用准直接驱动驱动的操纵器组成，以提供高度透明的力反馈。最终效应器具有双峰力传感器，可测量3轴力信息和2维接触位置。此信息用于防滑和重新磨碎反射。当用户与所需的对象接触时，重新抓紧反射将抓地力的手指与对象上的抗肌点对齐，以最大程度地提高抓握稳定性。反射仅需150毫秒即可纠正用户选择的不准确的grasps，因此用户的运动仅受到Re-Grasp的执行的最小干扰。一旦建立了抗焦点接触，抗滑动反射将确保抓地力施加足够的正常力来防止物体从掌握中滑出。本体感受器的操纵器和反射抓握的结合使用户可以高速完成远程执行任务。
We present a proprioceptive teleoperation system that uses a reflexive grasping algorithm to enhance the speed and robustness of pick-and-place tasks. The system consists of two manipulators that use quasi-direct-drive actuation to provide highly transparent force feedback. The end-effector has bimodal force sensors that measure 3-axis force information and 2-dimensional contact location. This information is used for anti-slip and re-grasping reflexes. When the user makes contact with the desired object, the re-grasping reflex aligns the gripper fingers with antipodal points on the object to maximize the grasp stability. The reflex takes only 150ms to correct for inaccurate grasps chosen by the user, so the user's motion is only minimally disturbed by the execution of the re-grasp. Once antipodal contact is established, the anti-slip reflex ensures that the gripper applies enough normal force to prevent the object from slipping out of the grasp. The combination of proprioceptive manipulators and reflexive grasping allows the user to complete teleoperated tasks with precision at high speed.
