Agenda
• Selected Concept● Vertical Traverse● Horizontal Traverse● Camera/Light Mounting● Microcontroller Selection● Functional Block Diagram● Self Leveling Pseudo-code● User Interface
Selected Concept
1
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 + Driveline2
Preliminary Analyses
● Static solid body analysis of fully-extended mast
● FEA of sliders● FEA of uprights
3
FBD - Top Stage

FBD - Base Stage
5
FEA - Stage Section
Minimum Safety Factor: 4.2
6
FEA - Slider
7Minimum Safety Factor: 6.2
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
9
● V-groove track system● Track lengths: 6’, 3’, and 1’● Vertex to vertex: 4’2”● Manual leveling feet ● Estimated Cost: $400
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
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)
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
