Abstract

The invention discloses a nonlinear teleoperation multilateral control method considering formation obstacle avoidance. Aiming at the obstacle environment, the present invention designs an obstacle avoidance planner based on the artificial potential function obstacle avoidance algorithm and the navigator switching algorithm, and constructs virtual force feedback on the master end, so that the operator can grasp the movement situation of the slave end navigator in real time, and at the same time , designed the slave formation controller to realize the formation movement of the slave robot avoiding obstacles under non-holonomic constraints; considering nonlinearity and various uncertainties, designed the master trajectory planner and master controller to realize the master robot's formation movement Superior tracking performance; finally, through the controller and slave formation controller, the global stability of the multilateral teleoperation system is guaranteed.

Description

technical field [0001] The invention belongs to the field of teleoperation control, and specifically relates to a nonlinear teleoperation multilateral control method considering formation obstacle avoidance, which can simultaneously ensure the stability and transparency of the nonlinear teleoperation system and the formation and formation of multi-agents from the terminal. Avoidance. Background technique [0002] In order to meet the task requirements of complex mobile scenarios, the multilateral teleoperation technology with formation-type slave robots has been continuously used in industrial environments, that is, the operator operates slave robots (multiple agents) at the master end to complete their tasks in obstacles. Formation and obstacle avoidance in the environment have been widely used in the fields of detection and handling, and have been widely studied as an important supporting technology in the field of robot applications. [0003] However, considering the non...
