  1. Vision + Robot=Flexible Automation

  2. Flexible Automation The vision about robots, vision and automation handling many products variants on a running standard conveyor

  3. What is the task for the vision? The primary task – Locate object • 3D – six dimensions • 2D – x,y and angle When located - Identification

  4. Classical Scenario One camera – above the conveyor – and a robot Communication – rs-232 Robot master : Get Part Vision answer : x,y,angle

  5. Scrabble Example • A PC with a monochrome 640 x 480 pixels firewire camera • Camera height 900 mm • Lens – 8 mm • Rexroth Bosch AR6 robot • Scorpion Vision Software • RS-232 communication • Cycletime - 200 ms – P4 2.0 GHz

  6. Image processing • Segmentation • Blob • Pattern Matching • Orientation • Pattern Matching • Line Finders • Result x,y and angle

  7. Vision – Robot Calibration • A standard four-point calibration dominates the 2D robot vision • Calibration done manually when system is offline • Vision works i robot coordinates

  8. Identification • Identificates the letter using a template-matcher • A smart resampling means that the system handles rotation, perspective and size changes with ease.

  9. Other examples • Automatic palleting with Motoman robot

  10. Blockdiagram

  11. System Protocol • PLC transmits trigger to Scorpion • Scorpion capture image return one of the following over RS 232 • OK Angle • Error tag • Angle not OK • Cannot Measure

  12. Flexible Picking • Randomly feeding products on 8 conveyors. • 2 robots picking and packing guided by Scorpion Vision Software • Video

  13. Mounting contacts • Bosch robot mount contact • Vision checks that the pins are OK

  14. Measure Angle • Motoman Robot holds object • Vision measure angle

  15. Conclusion • Many possibilities for the innovative • Cost of robot vision is dropping • Standard hardware • Proven and configurable software

  16. One solution for all Vision Systems • Configurable Software • MMI • Vision Tools • Process Insight • Communication • Standard • Cameras • PC • Windows 2000/XP
