P14542: Vertical XY Camera Rig Subsystems Design Review Oct-29-13
Agenda • Selected Concept • Vertical Traverse • Horizontal Traverse • Camera/Light Mounting • Microcontroller Selection • Functional Block Diagram • Self Leveling Pseudo-code • User Interface
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
Preliminary Analyses • Static solid body analysis of fully-extended mast • FEA of sliders • FEA of uprights 3
FEA - Stage Section Minimum Safety Factor: 4.2 6
FEA - Slider Minimum Safety Factor: 6.2 7
Vertical Traverse - Next Steps • Pulley/Cable System • Incorporate Friction from Sliders • Drive System • Dynamic Analysis • FEA of Connecting Bars • Adjustable Limit Switches 8
Horizontal Traverse • V-groove track system • Track lengths: 6’, 3’, and 1’ • Vertex to vertex: 4’2” • Manual leveling feet • Estimated Cost: $400 9
FEA - Track Rail Max deflection: 0.0231” Minimum factor of safety: 9 10
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
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
FEA - Camera Mount • Center loaded camera mounting surface simply supported. 13
FEA - Lighting Mount • Simplified model cantilevered from the rig at max extension.
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
