    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Force Controlled Grinding; Automated Deburring; Cleaning of Castings; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : An increasing number of robots have been used for the finishing of castings during recent years. This is mainly due to developments to overcome problems that restricted their use during the past decade. LÄS MER

  3. 12. Simulation of robot paths and heat effects in welding

    Författare :Mikael Ericsson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsteknik; Welding; Automation; robotics; Off-line programming; Robotics; Automatiska system; Production technology; control engineering; Finite Element Analysis; reglerteknik; robotteknik;

    Sammanfattning : The objective of this thesis is to develop a simulation tool and a method by which robot trajectories, temperature histories, residual stresses and distortion can be analysed and optimized off-line. This was performed by integrating robot simulation software with finite element analysis software. LÄS MER

  4. 13. On Reduction of Production Disturbances in Manufacturing Systems Based on Discrete-Event Simulation

    Författare :Arne Ingemansson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatiska system; robotteknik; reglerteknik; Production technology; Produktionsteknik; control engineering; robotics; Automation; manufacturing system; Discrete-event simulation DES ; production disturbance reduction;

    Sammanfattning : Improved efficiency in manufacturing systems to achieve increased output and thus reduced production disturbances is a vital area. DES (Discrete-Event Simulation) can visualize and study the dynamic issues related to total efficiency in manufacturing systems. A methodology for production disturbance reduction is presented.

  5. 14. On Sensor-Controlled Robotized One-off Manufacturing

    Författare :Per Cederberg; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; one-off manufacturing; arc welding; world model; real-time; task-oriented programming; simulation; control; robotics; sensor; Automation; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : A semi-automatic task oriented system structure has been developed and tested on an arc welding application. In normal industrial robot programming, the path is created and the process is based upon the decided path. Here a process-oriented method is proposed instead. LÄS MER

  7. 15. Design and Implementation of Embedded Video Surveillance Hardware
