  1. Development of Robotic Machine Tool Towards Industrial Business Huapeng Wu , Heikki Handroos Lappeenranta University of Technology

  2. Background • Since 2000, the EFDA in EU has launched several tasks to develop an intersector welding robot (IWR) for carrying out welding and machining inside the VV . The Laboratory of Intelligent Machine in Lappeenranta University of Technology has participated the related projects and developed Three generations of special hybrid machines as the solutions to the tasks. • The machining, welding and handing tests have been carried out in this laboratory by cooperating with CEA in France, VTT in Finland and Ansaldo in Italy. • In 2006, the EFDA evaluated the different possible methods based on the commercial serial robots, the special machines and the IWR robot. The evaluation report concluded that the hybrid parallel robot IWR is the best solution to the required tasks.

  3. 1) First generation of parallel robot machine Prototype and Control System Integration Hydraulic station

  4. First generation of parallel robot machine -Technical achievements from first Version Five degree of freedom full parallel robot Penta-WH Stainless steel martial cutting Stainless steel Laser welding , Seam tracking algorithm Control software for Robot and CNC functions Control strategy for hydraulic servo control Calibration method with Differential evolution algorithm Communication algorithm for different control system ( local NetWare ) Stainless cutting softerware Laser welding with seam tracker

  5. 2) Second generation of parallel robot machine

  6. Second generation of parallel robot machine -Technical achievements from second Version Ten degree of freedom Hybrid parallel robot IWR Stainless steel martial milling Control software for Robot and CNC functions Control strategy for robot tracking motion Calibration method with MCMC algorithm Man-machine interface Trajectory planning takes into account deflection Machining vibration suppressing.

  7. 3) Third generation of parallel robot machine Robot machine With milling tool 6-Degree of freedom Robot machine 3 linear motion and 3 rotation for handing , welding and machining No extra machine head and handing beam are need Robot machine With splice plate holder

  8. 2. Application to industry from the developments • 1. Parallel mechanism applications • Realtime Simulator ( mobile machine, robotremotehanding….) • Mobile Machine • High speed Machine . Mobile machine MeVEA Ltd awarded the national Innofinland 2011-prize Application in simulator Fast speed for laser cutting

  9. Application to industry from the developments 2. Laser tracking , Machine vision and CAD/CAM

  10. Application to industry from the developments 4. Calibrationmethod for general robot by laser beam with machine vision 1 . Robot : it can be any robot used In the company. The link parameters Can be found from producer. 2. Laser beam : single laser beam with Dot pattern. 3. High resolution camera 4. Aluminium cube, 80mmx80mmx80mm 3 2 2 3 1 4

  11. Application to industry from the developments 5. Suppress Chatter for industrial robot machine Hybrid control strategy for Chatter suppressing

  12. Application to industry from the developments 6 .Control of robot by using standard industrial PC Software developing for industrial applications.

  13. Application to industrious from the developments 7. Reconfiguration of robot for different tasks • Hardware reconfiguration • Software reconfiguration • Man- machine cooperation to complete tasks Application in FMS system

  14. 3. Future work – development for industrial application • Commercialized calibration methods • commercialized vibration suppress control methods • commercialized Hardware and software for robot machine • Commercialized mobile robot machine • Commercialized CAD\CAM\MV for robot applications Spin- off company

  15. 4. Conclusions Three robots have been developed for ITER application. Several technologies developed have been or will be applied to industrial application other than ITER. Future work will be aimed into commercial business
