    Abstract: A system, method, and apparatus for a robot system that manipulates the surface of an object effect programmed manipulation goals such as reaching specific locations on the surface of the object, displacing the surface of the object, applying a predetermined force and torque to the surface of the object, dynamically changing the contact point between the robot and the object, and applying force to structures below the surface of the object. The system and method determine the state of the object through a sensing method that includes, without limitation: torque and force measurement, visible light sensors, range and depth sensors, ultrasound sensors, thermographic sensors, and worktable force measurement.

    Abstract: A control system of a surgical robot arm, the surgical robot arm comprising a series of joints by which the configuration of that surgical robot arm can be altered, an attachment for a surgical instrument at a distal end of the robot arm and one or more force or torque sensors, each force or torque sensor configured to sense a force or torque at a joint of the series of joints; the control system being configured to control the configuration of the surgical robot arm to be altered in response to an externally applied force or torque by: receiving sensory data from the one or more force or torque sensors indicative of a sensed force or torque at a point of the surgical robot arm resulting from the externally applied force or torque; resolving the sensed force or torque so as to determine the components of the sensed force or torque acting at the point in a direction parallel with the longitudinal axis of a surgical instrument attached to the attachment; and sending a command signal to the surgical robot arm to drive the robot arm such that the configuration of the robot arm is altered so as to comply with the resolved force or torque components.

    Abstract: 一种基于力反馈的机器人实时运动规划方法,针对在较大周期姿态修正量下,机械臂不能平滑加/减速运动的问题,修正了现有的分段线性力位控制方法。采用六维力传感器感知外部作用力,获取坐标系各轴每周期姿态目标修正量;并通过各坐标轴稳定运行时的最大周期姿态修正量增量确定各轴每周期姿态修正量插补步幅基数,最后通过力位转换、插补逼近各轴的周期姿态目标修正量,避免了机械臂启动或停止时,运动状态的改变导致的震荡,实现机械臂力控过程中的平滑运动。

    Abstract: Systems and methods for constrained motion control of medical instruments are provided. In one aspect, a robotic system includes an instrument having an end effector, a robotic arm configured to control movement of the instrument and the end effector, and an input device configured to receive an input for controlling movement of the instrument and end effector. The instrument is capable of moving in a different number of degrees-of- freedom (DOFs) than the input device. The system is configured to determine a Jacobian matrix relating the input to the input device to robotic arm commands for achieving a motion of the end effector indicated by the input, modify the Jacobian matrix via discarding at least one row of the Jacobian matrix, and determine a robotic arm command for achieving the motion of the instrument indicated by the input based on the modified Jacobian matrix.
