... coefficient of the controller was adjusted according to the stiffness of the tip of the human operator's arm. This stiffness was estimated in real time from the experimental data of the force and the position of the robot end effector. Human–robot comanipulation Human–robot interaction Impedance...

...Chengguo Zong; Zhijian Ji; Junzhi Yu; Haisheng Yu Purpose The purpose of this paper is to study the adaptability of the tracked robot in complex working environment. It proposes an angle-changeable tracked robot with human–robot interaction in unstructured environment. The study aims to present...

...Chengguo Zong; Zhijian Ji; Haisheng Yu Purpose This paper aims to provide a theoretical principle for the stability control of robot climbing stairs, autonomously based on human–robot interaction. Through this research, tracked mobile robots with human-robot interaction will be extensively used...

...Ningbo Yu; Wulin Zou Purpose This paper aims to present an impedance control method with mixed H₂/H_∞ synthesis and relaxed passivity for a cable-driven series elastic actuator to be applied for physical human–robot interaction. Design/methodology/approach To shape...
