  3. 3. Compliance Control of Robot Manipulator for Safe Physical Human Robot Interaction

    University dissertation from Örebro : Örebro university

    Author : Muhammad Rehan Ahmed; Ivan Kalaykov; Kystof Kozlowksi; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physical human robot interaction; collision safety; variable stiffness actuators; compliance control; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY Information technology Automatic control; TEKNIKVETENSKAP Informationsteknik Reglerteknik; Reglerteknik; Automatic Control;

    Abstract : Inspiration from biological systems suggests that robots should demonstrate same level of capabilities that are embedded in biological systems in performing safe and successful interaction with the humans. The major challenge in physical human robot interaction tasks in anthropic environment is the safe sharing of robot work space such that robot will not cause harm or injury to the human under any operating condition.
