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 + Driveline

2

Preliminary Analyses

● Static solid body analysis of fully-extended mast

● FEA of sliders● FEA of uprights

Vertical Traverse - Next Steps

• Pulley/Cable System

• Incorporate Friction from Sliders

• Drive System

• Dynamic Analysis

• FEA of Connecting Bars

• Adjustable Limit Switches

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
