1. 1. Development of intelligent robot systems based on sensor control

   Författare :Mikael Fridenfalk; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Envision; kinematics singularities.; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik; Igrip; Matlab; 6D; 3D; laser scanning; arc sensing; seam tracking; robotic welding; Asimov; ROWER-2; FUSE; virtual prototyping; rapid prototyping; software development; simulation; virtual sensor; Robot; sensor control;

   Sammanfattning : Sensor based control systems increase flexibility and autonomy in robotics. One of the most common applications in robotics is welding, which is often limited to objects with fine tolerances. LÄS MER

3. 2. 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

4. 3. Om vikten av att i automationsprocessen integrera handens och hjärnans arbete

   Författare :Bertil Gustafsson; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Tacit knowledge; Small scale production; Operator´s computer; Cross-functional work teams; Robot arc welding; Decentralised work organisation;

   Sammanfattning : This licentiate report attempts to add to our knowledge of how the competence of skilled workers can be incorporated into modern manufacturing systems, without depriving them of the status that they had earned through their previous specialised skills and knowledge. The work is concentrated on establishing a theoretical basis for a model of how the computer can support this work: the Operator's Computer approach has been applied in three case-studies, thus taking it over the threshold into the Swedish engineering industry.

5. 4. Optical detection of joint position in zero gap laser beam welding

   Författare :Morgan Nilsen; Anna-Karin Christiansson; Fredrik Sikström; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser beam welding; Optical sensors; Joint tracking; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : This thesis presents an experimental study on how to track zero gaps between metal sheets to be joined by laser beam butt welding. Automated laser beam welding is gaining interest due to its ability to produce narrow and deep welds giving limited heat input and therefore less distortions compared to other processes, such as arc-welding.

7. 5. Simulation and execution of autonomous robot systems

   Författare :Magnus Olsson; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Elektronik och elektroteknik; sensor simulation robotics; Electronics and Electrical technology; control engineering; Automatiska system; robotteknik; reglerteknik;

   Sammanfattning : Traditional off-line programming is not enough in order to use the full potential of virtual models and simulation system in industrial robot applications. The interface between off-line programming system and the robot controller is today restricted to program transfer. LÄS MER
