  2. 12. Multimodal Human-Robot Collaboration in Assembly

    Author : Sichao Liu; Lihui Wang; Gunnar Bolmsjö; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics; Assembly; Human-robot collaboration; Multimodal control; Function block; Production Engineering; Industriell produktion;

    Abstract : Human-robot collaboration (HRC) envisioned for factories of the future would require close physical collaboration between humans and robots in safe and shared working environments with enhanced efficiency and flexibility. The PhD study aims for multimodal human-robot collaboration in assembly. READ MORE

  3. 13. Semi-Automating Forestry Machines : Motion Planning, System Integration, and Human-Machine Interaction

    Author : Simon Westerberg; Anton S. Shiriaev; Klas Nilsson; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forestry Robotics; Forest Machine Automation; Trajectory Planning; Hydraulic Manipulators; Teleoperation; Virtual Environments; Interaction Methods; Head Tracking;

    Abstract : The process of forest harvesting is highly mechanized in most industrialized countries, with felling and processing of trees performed by technologically advanced forestry machines. However, the maneuvering of the vehicles through the forest as well as the control of the on-board hydraulic boom crane is currently performed through continuous manual operation. READ MORE

  4. 14. Design and Evaluation of a Compact 15 kW PM Integral Motor

    Author : Peter Thelin; KTH; []
    Keywords : integral motor; integrated motor drive; PM motor; PMSM; compact motor; filter coil; airgap flux density; axial leakage;

    Abstract : This thesis deals with the integral motor of tomorrow, and particularly with a variable speed, sensorless permanent magnet synchronous motor with an integrated converter. The rated power is 15 kW at 1500 r/min. The outer dimensions are approximately the same as for the equivalent standard induction motor.Control strategies for pumps and fans, i. READ MORE
