1. P14542: Vertical XY Camera Rig Subsystems Design Review Oct-29-13

2. Agenda Selected Concept ●Vertical Traverse ●Horizontal Traverse ●Camera/Light Mounting ●Microcontroller Selection ●Functional Block Diagram ●Self Leveling Pseudo-code ●User Interface

3. Selected Concept 1

4. Vertical Traverse Overview ●5 stage telescoping mast ●Collapsed Height: 5’4” ●Extended Height: 20’ ●Delrin sliders at joints ●Estimated Total Weight: 150 lbs ●Estimated Total Cost: $2000 + Driveline 2

5. Preliminary Analyses ●Static solid body analysis of fully-extended mast ●FEA of sliders ●FEA of uprights 3

6. FBD - Top Stage 4

7. FBD - Base Stage 5

8. FEA - Stage Section Minimum Safety Factor: 4.2 6

9. FEA - Slider 7 Minimum Safety Factor: 6.2

11. Vertical Traverse - Next Steps Pulley/Cable System Incorporate Friction from Sliders Drive System Dynamic Analysis FEA of Connecting Bars Adjustable Limit Switches 8

12. Horizontal Traverse 9 ●V-groove track system ●Track lengths: 6’, 3’, and 1’ ●Vertex to vertex: 4’2” ●Manual leveling feet ●Estimated Cost: $400

13. FEA - Track Rail Max deflection: 0.0231” Minimum factor of safety: 9 10

14. Horizontal Traverse - Next Steps Reduce track deflection Improve cross-bracing Connection system “Roller Coaster” wheel system Generate other track lengths End section Design cart 11

15. Camera/Light Mounting 12 ●Vertical slides mounted to the “double rail” of the inner stage. ●Vertical and Horizontal Lighting Mounts ●Lighting is capable of rotating 90º and extending linearly from the rig ●Camera Mounting surface using linear motion slides. ●Camera is able to move 1’ linearly (forward and back)

16. FEA - Camera Mount Center loaded camera mounting surface simply supported. 13

17. FEA - Lighting Mount Simplified model cantilevered from the rig at max extension.

18. Camera & Lighting - Next Steps Vertical slider analysis and FEA modeling Lighting hinge analysis. Hardware selection Safety system for lighting rotation. Obtain lighting and mounting hardware for prototype system

19. Microcontroller Selection 14

20. Functional Block Diagram 15

21. Self-Leveling System Pseudo-code 16

22. User Interface 17
