In this article, an admittance-based controller for physical human-robot interaction (pHRI) is presented to perform the coordinated operation in constrained task space. An admittance model and a soft saturation function are employed generate differentiable reference trajectory ensure that end-effector motion of manipulator complies with human avoids collision surroundings. Then, adaptive neural network (NN) involving integral barrier Lyapunov (IBLF) designed deal tracking issues. Meanwhile,...

Comparative simulation results carried out verify effectiveness emphasize advantages...
Purpose This paper aims to propose cooperative control strategies for dual-arm robots in different human–robot collaborative tasks assembly processes. The authors set three regions where robot performs ways: “teleoperate” region, “co-carry” region and “assembly” region. Human holds the “master” arm of operate other “follower” by our proposed controller “teleoperation” Limited human length, is teleoperated carry distant object. In cooperatively object close human. used fixing coupled with...

This paper proposed an adaptive neural admittance control strategy for collision avoidance in human-robot collaborative tasks. In order to ensure that the robot end-effector can avoid collisions with surroundings, should be operated compliantly by human within a constrained task space. An impedance model and soft saturation function are employed generate differentiable reference trajectory.
