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

    Författare :Muhammad Rehan Ahmed; Ivan Kalaykov; Kystof Kozlowksi; Örebro universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physical human robot interaction; collision safety; variable stiffness actuators; compliance control; TECHNOLOGY; TEKNIKVETENSKAP; Automatic control; Reglerteknik; Reglerteknik; Automatic Control;

    Sammanfattning : 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.

  3. 2. Conducting Polymer-based Biohybrid Materials : Towards Microphysiological Chips and Soft Actuators for Bone Tissue Engineering

    Författare :Danfeng Cao; Edwin Jager; Jose Gabriel Martinez Gil; Jonathan Rossiter; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The human body is a complex system, consisting of different types of biomolecules and living matters, such as nucleic acids, proteins, carbohydrates, lipids, serum, cells, tissues, and organs. These complex biomolecules and living matters integrate and interact dynamically to perform and maintain body functions. LÄS MER

  4. 3. Human Postures and Movements analysed through Constrained Optimization

    Författare :Robert Pettersson; Anders Eriksson; Elena Gutierrez-Farewik; Hans Berg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multibody system; optimal control; trajectory optimization; long jump; posture; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : Constrained optimization is used to derive human postures and movements. In the first study a static 3D model with 30 muscle groups is used to analyse postures. The activation levels of these muscles are minimized in order to represent the individual's choice of posture. LÄS MER
