1. DESIGN NOW WHAT Ken Hilke CAD Instructor Butler County Area Vo-Tech School

4. The Rule of Budgets Design Process Weight Power Cost Miscellaneous TimeKnowledge

5. The Great 8 Select the Best Ideas Visualize the Ideas Understand the Problem Develop Ideas Evaluate Build and Test Create Drawings Integrate Mix and Match the Steps, but Understand the Problem

6. Design Considerations  What competition tasks will your robot do?  Blocker  Simplest  Consider a very simple autonomous mode  Power  Able to work with other robots  Maneuverable  Setter  Control  Manipulator  End game  Ramp  Lifter

7. Design Considerations. How will the robot move?  One or two wheel steer  Four wheels ( each side connected )  Two wheels with casters  Tracks  Other

8. Design Considerations..  What will the robot be required to do?  Lift Arm  Telescoping  Electric or pneumatic  Shoulder elbow type  5 basic arm types

9. Articulated Robot

10. Design Considerations…  What will the robot be required to do?  Sensing  Positioning  Stops  By operator  Grasp  Clamp  Suction  Conveyer  Lifter

11. Design Considerations….  How much will it weigh  How will I weigh it.  How big can it be  See size in rules  Can expand after comp. begins  Pay Attention   Sharp corners   Edges   Protrusions   Pinch points

12. Design Considerations…..  Shields  Covers for difficult areas  Bumpers and pads  Not covered in weight restriction  Pneumatics  Better linear movement  Better variable pressure  Slower moving  Single acting cylinders require less air

13. Things to remember.  Working Stand  Keep It Simple Stupid  Flags  Team Number  Operation Light  ( waved last year in Pittsburgh competition )  Weight is the enemy  Aluminum is your friend  8020 the industrial erector set  www.8020.net

14. Things to remember..  Put all sensitive parts inboard  Keep weight low and balanced  Accessibility ( batteries, on/off switch )  Build strong  Build light  Change is OK

15. Documentation www.usfirst.org Documents and Updates Competition Manual and Related Documents ( more when it comes available ) Team Resources Technical 3D Drawing FIRST Cad Library Archived Game Docs and Event For Teams, By Teams Print

16. The KIT a box of parts  Separate the kit into sections  Electrical  Pneumatic  Mechanical  Go through the checklist  What is missing?  Nothing and Everything

17. Power Distribution Drawing

18. Controller Connection Diagram

19. Test Bed  Two roles of wire ( black & Red )  Spade terminals to start  Make sure of polarity  Does not show control connections  Set team number  Use basic control program

21. Pneumatics Kit – what you get

24. The BASE  Check the manual for size.  Assemble base

25. Wheel Design ( Last Year )

26. Programming  Choices  Labview  RobotC  EasyC  MPLab

27. Shipping Create  Build to the maximum size ( 4’x4’x70” )  Wood is easiest ( 400 lb max weight )  Consider opening and closing  Battery compartment  Signs  Decorate it  Ship it (Feb 19, 2008 )  Save it

28. What do you do with last years robot?  Test Bed to work on all year  Make it into something fun
