  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 Minimum Safety Factor: 6.2 7

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

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

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

  13. 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

  14. Camera/Light Mounting • 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) 12

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

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

  17. 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

  18. Microcontroller Selection 14

  19. Functional Block Diagram 15

  20. Self-Leveling System Pseudo-code 16
