    Sammanfattning : daptive responsive environments that encourage interaction for children with severe disabilities offer a distinct potential for play and learning in rehabilitation. Physical training and therapy for these children is often enduring, tedious, and boring through repetition - and this is often the case for both the child and the facilitator/therapist. LÄS MER

  4. 3. High-Speed Vision and Force Feedback for Motion-Controlled Industrial Manipulators

    Författare :Tomas Olsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Force vision control; Visual tracking; Visual servoing; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : Over the last decades, both force sensors and cameras have emerged as useful sensors for different applications in robotics. This thesis considers a number of dynamic visual tracking and control problems, as well as the integration of these techniques with contact force control. LÄS MER
