Additionally, the control system may estimate an aggregate orientation of the robot based on the first plurality of measurements, the body orientation measurement, and the determined relationship. Further, the control system may provide instructions to control at least one jointed limb of the robot based on the estimated aggregate orientation of the robot.
MOTION MONITORING OF A ROBOT MANIPULATOR
A device and method for monitoring a motion of a robot manipulator, including operations of: defining a forbidden position for the robot manipulator, defining a curve running along the robot manipulator with a one-dimensional running coordinate s, wherein at least a subset of all locations of the curve is moved together with a current pose of the robot manipulator, and determining a distance d between a location of a current curve and/or a predicted curve and the forbidden position.
ROBOT CONTROL DEVICE, INFORMATION PROCESSING DEVICE, AND ROBOT SYSTEM
A robot control device includes a robot control section that controls a robot. The robot control device outputs, to another device, second information associated with first information indicating operation being executed by the robot control section, the operation being operation for causing the robot to perform work.
SURGICAL ROBOTIC SYSTEM AND CONTROL OF SURGICAL ROBOTIC SYSTEM
A surgical robotic system is provided for use in a surgical procedure. The surgical robotic system comprises a surgical arm (080) comprising a movable arm part (082) for mounting of a surgical instrument (119), the movable arm part having at least one degree-of-freedom to enable longitudinal movement (109) of the surgical instrument towards a surgical target (123). A human machine interface (020) is provided for receiving positioning commands (022) from a human operator for controlling the longitudinal movement of the surgical instrument, and an actuator (060) is configured and arranged for actuating the movable arm part to effect the longitudinal movement of the surgical instrument. The actuator is controlled by a processor in accordance with the positioning commands and a virtual bound (132-135). The virtual bound establishes a transition in the control of the longitudinal movement of the surgical instrument in a direction towards the surgical target. The virtual bound is determined, during use of the surgical robotic system, based on the positioning commands.
Advantageously, the human operator is provided with safer and/or more accurate control over the surgical instrument in the vicinity of a surgical target.

Data-driven position estimation and collision detection for flexible manipulator
A flexible manipulator apparatus includes an elongate flexible manipulator having a sensor, a user output device configured to provide sensory outputs to the user, and processing circuitry. The flexible manipulator may be movable to form a curve in the flexible manipulator. The processing circuitry may be configured to receive captured sensor data from the sensor during movement of the flexible manipulator, and determine a collision likelihood score based on application of the captured sensor data to a collision detection model used for position estimation. The collision detection model may be based on an empirical data training for the flexible manipulator that includes training sensor data from the sensor and training image data of positions of the flexible manipulator. The processing circuitry may be configured to control the user output device based on the collision likelihood score to provide a collision alert sensory output to the user.
COLLISION TESTING ON THE BASIS OF HIGH-QUALITY GEOMETRY
Elements of a machine are moved relative to one another along several axes. A monitoring device receives groups of position values of the axes which specify the relative position of the elements to one another. The surfaces and/or volumes of the elements taking up working space are determined therefrom. The monitoring device checks whether a collision risk between the elements exists. The monitoring device models at least parts of the surfaces of the elements with two-dimensional splines defined by nodes and checkpoints. The monitoring device further determines from the checkpoints of the splines for sections envelopes which envelop respective element in the respective section, and uses the respective envelope as a surface that is taken up by the respective element in the respective section. Boundary lines of faces of the envelopes are straight connecting lines of the checkpoints.
Method for collision detection and autonomous system
