Abstract

The invention belongs to the technical field of robot teleoperation systems. The invention discloses a control method of a teleoperation system with virtual constraint. Virtual force is generated according to point-to-point position difference, and the problem of large tracking error in the prior art is solved. The control method of the teleoperation system with the virtual constraint comprises the following steps of mapping the position difference between an actual position B and a task position A of an end effector of a slave robot to the end of a main robot when the slave robot is operatedto move within a certain range of a target object by the main robot; generating a virtual force signal by a virtual spring, feeding the force signal back to the main robot, forming the virtual constraint by the main robot, and restraining an operator to operate according to the virtual constraint. According to the control method, the system structure is simplified, the equipment cost is reduced, the operating burden of the operator can be reduced, the accuracy of the system is increased, the task execution capability of the robot is increased, and the practicability of the teleoperation systemis increased.

Description

technical field [0001] The invention belongs to the technical field of remote operating systems for robots, and relates to robot control technology, in particular to a control method for remote operating systems with virtual constraints. Background technique [0002] The robot teleoperation system combines human experience and wisdom with the advantages of robots, and realizes the extension of human behavior ability, so it is widely used in engineering practice in dangerous or complex environments. The teleoperation system control method with virtual constraints simplifies the system structure, saves equipment costs, eases the operator's operating burden, increases the accuracy of the teleoperation system, and provides a good engineering application for the teleoperation system Technical Support.
