Competition Scoring: Metrics and Index
Competition Scoring: Metrics and Index
The SD 60 Go-Kart Rodeo is scored based on technical merit, fabrication quality, and power efficiency, not just raw speed. The three main challenges contribute points to a final championship score, with separate streams for Manual Karts and Autonomous Karts.
1. Manual Kart Scoring Stream
1. Manual Kart Scoring Stream
A. Technical Fabrication Inspection (The Shop Test)
A. Technical Fabrication Inspection (The Shop Test)
This mandatory inspection scores craftsmanship and verifies structural integrity. Karts must pass all safety checks to proceed.
Mandatory Safety Pass: (Non-Negotiable) Check of all critical safety features (roll cage, steering, harnesses, etc.). Teams must pass to compete.
Fabrication Quality: Points awarded for precise joint fit-up, weld consistency, and sound structural choices.
Aesthetic Considerations: Points awarded for the professional finish, clean routing of components, and overall presentation.
Verification Trial: The Fastest raw time recorded during the mandatory 3-lap track trial immediately following the inspection.
B. Maximum Torque Challenge (WEI Score)
B. Maximum Torque Challenge (WEI Score)
This challenge determines the vehicle's true Work Efficiency Index (WEI), normalizing performance across all kart designs by using a fixed, maximum load in the sled pull.
Scored Components:
Custom Sled Fabrication: Points awarded for low-friction runner design, structural integrity, and aesthetic workmanship of the custom-fabricated sled.
WEI Final Score: Calculated using the formula below.
Work Efficiency Index (WEI) Calculation:
The WEI measures the Work Done (load moved per second) relative to the kart's Maximum Power Potential (ST). The highest WEI score wins.
The WEI calculation uses four measured variables:
Static Torque Result (ST): The Maximum Static Pull Force (in lbs) recorded on the sponsored dynamometer. (Measures Max Power Potential.)
Sled Weight (WS): The measured weight of the student-fabricated sled (in lbs).
Work Weight Pulled (WP): The weight of the gravel volume successfully pulled (in lbs).
Time (T): The time recorded for the successful turnaround pull.
B. Open Run Challenge (Performance) Scoring Formula
B. Open Run Challenge (Performance) Scoring Formula
The Open Run Challenge total is worth 450 points (sum of the five stations). Teams are scored based on their Rank within the competition field for each event.
How the Challenge Works:
How the Challenge Works:
Total Work Weight Determination: Teams are tasked with pulling the maximum load supported by their karts. This load (WP) is created using the fabricated sled filled with the maximum number of 5-gallon buckets of pre-weighed gravel that the kart is capable of pulling, as determined by each individual team.
Static Torque (ST): Your kart's maximum potential pull force is measured on the dynamometer before the pull. This value in the denominator serves as the normalization factor to keep the efficiency metric fair.
Pull Test: The kart attempts to pull this maximum individual load over a specified, fixed distance across the field.
Time Measurement: The time measurement starts when the kart begins moving and stops when the sled fully crosses the finish line.
Special Scoring: Station A - Endurance Circuit (50 Points)
Special Scoring: Station A - Endurance Circuit (50 Points)
Due to its focus on durability, this station is scored differently:
50 Points: Awarded to any team that successfully completes the required number of laps without mechanical failure or required staff intervention.
0 Points: Awarded to any team that suffers a major mechanical failure (e.g., lost wheel, broken steering) or requires a Red Flag intervention by staff.
