Overview Mechanical Design Electrical Design - System - Chassis - Suspension/Steering - Individual Modular Prototype Electrical Design - System - Resistance Settings - Proof of Concept

Chassis 2” x 4” 0.250 wall Rectangular and square A36 mild steel tubing -Yield strength of 36,000 psi Simple 90 and 45 degree angles -Simplify fabrication -Reduce production costs Final design of the frame came to a total weight of 729 lbs.

Chassis Displacement - 1000lb applied to front suspension mount Max displacement: 0.504” Max Von Mises -1000lb applied to front suspension mount Majority of frame at <6,000 psi von Mises stress, SF ≈ 6.0 Displacement - Max Displacement w/ 250lb per module: 0.0137 Max von Mises Stress w/ 250lb per module: 17,670 psi, SF = 2.05
