Criteria Current Design Proposed Designs Compilation Foot Plate Analysis and Design

Foot Plate Criteria Function: 1. Support weight of subject a lbs (500 lbs per plate) 2. Maintain similar performance to current a. Deflection b. Maximum Stress

Boundary Conditions and Force Top Bottom ” diameter 0.75 from top 0.75 from side

Current Foot Plate Boundary Conditions: UY = 0 in 3 corners, UX, UY, UZ = 0 in 1 corner Force: -125 lbs in 4 locations around center point Max deflection: in Max stress: 3629 psi Footprint Dimensions: in x 7.95 in Thickness: in Density of 6061-T6: lb/in^3 Weight = 4.35 lbs Maximum Stress = 7,316 psi Maximum Deflection = in

Foot Plate Designs Possible Design Change Avenues: 1. Thickness a. Aluminum b. Reduce to 0.25” from 0.375” 2. Material a. Steel Alloy b. Use thickness of 0.125” 3. Geometry a. Drill out Hole Pattern b. Mill out Material (through 0.25”) c. Mill out Material (through all)

Change Thickness Footprint Dimensions: in x 7.95 in Thickness: 0.25 in Density of 6061-T6: lb/in^3 Weight = 2.90 lbs Maximum Stress = 15,861 psi Maximum Deflection = in

Change Material: ASTM A36 Steel Footprint Dimensions: in x 7.95 in Thickness: in Density of ASTM A36: 0.28 lb/in^3 Weight = 4.21 lbs Maximum Stress = 60,327 psi Maximum Deflection = in

Change Geometry: Drill out Holes Footprint Dimensions: in x 7.95 in Thickness: in Density of 6061-T6: lb/in^3 Weight = 4.15 lbs Maximum Stress = 8,377psi Maximum Deflection = in

Change Geometry: Mill out Material (Through 0.25”) Footprint Dimensions: in x 7.95 in Thickness: in Density of 6061-T6: lb/in^3 Weight = 2.68 lbs Maximum Stress = 14,358psi Maximum Deflection = in

Change Geometry: Mill out Material (Through All) Footprint Dimensions: in x 7.95 in Thickness: in Density of 6061-T6: lb/in^3 Weight = 1.85 lbs Maximum Stress = 24,305psi Maximum Deflection = in

Analysis Comparison Moving Forward: 1. Optimize drill and mill designs, determine best configuration 2. Source pricing for each method 3. Make final decision on plate design

Required Functions Enable West/East (W/E) Adjustment of Foot Plates. Allow User to Access Foot Plates Maintain Alignment of Foot Plates Proposed Concept Foot Plate Track Design

Proposed Design  Allow W/E Adjustment UnextendedFully Extended Note: Movement is limited by width of foot plate. W/E track is perpendicular to the North/South (N/S) track. W/E track enters side of foot plate base at height to allow base to sit on the ground to protect against vertical bending. W/E movement is limited by width of foot plate base. Two W/E tracks are used to protect against horizontally. Will probably add less than 1 pound of additional weight.

Split into required functions Maintain Camera Orientation Maintain Orientation Layouts Maintain and adjust Camera Height Camera structure portability Maintain Camera Stability Camera Structure Selected Concepts Compilation Camera Structure Design

Maintain Camera Orientation  Function:  Maintain Camera X and Y position from the footpad across multiple set ups.  Priorities: minimize human error, weight.

Maintain Orientation Layouts  Function: Maintain proper camera locations  Priorities: minimize material (weight), aesthetics

Maintain and Adjust Camera Height  Function:  Maintain and adjust Camera Z position  Priorities: minimize human error, weight.

Camera Structure Portability  Function:  Allow for structure portability  Must disassemble into 61” x 48”x 8” carrying case  Priorities: minimize human error, weight.

Maintain Camera Stability  Function:  Allow for Camera Stability  Priorities: Minimize Camera Movement, Minimize weight
