What Judges Recognized ✓

"The redesign process was well researched and you were experts on each part!"

Innovation Project

"Great job including each member and clarifying everyone's expertise."

Core Values

"Great impact for sharing with your community with your hosted event."

Core Values

The Root Problem

"Wasting time in the wrong areas"

The Guesswork Chain

We emailed 300+ professionals across 4 countries. 5 wrote back. Each one changed our drone — from sensor choice to frame material to power source. Our research with Dr. James McGrath-Seegmiller proved that guesswork isn't just slow — it's dangerous. When archaeologists dig "blind," it triggers a cascade of failures:

Artifact Damage

Blind digging destroys fragile history before it can ever be mapped or protected.

Tunnel Collapse

Undetected subterranean voids pose immediate safety risks to the field crews.

Eco Destruction

Unnecessary trial pits ruin local ecosystems and native soil composition forever.

Wasted Funding

Manual labor currently consumes months of budget on empty dig sites.

Visualizing the Challenge

FLL Judging Category · Innovation Project

Innovation Project

DRONOTICS · Precision Remote Sensing Ecosystem

LiDAR Scanner

Penetrates dense jungle canopies to generate 3D bare-earth topography, revealing hidden ruins unseen for centuries.

Dual GPR

Ground Penetrating Radar detects buried masonry and subterranean density anomalies without disturbing a grain of soil.

GIS Mapping

Coordinate-syncing sensor hits to a global grid for layered, high-precision digital site documentation in real-time.

AI Detection

Custom computer vision models trained to identify artifact shapes and construction patterns automatically during flight.

Scalability & Impact

Solving a $30B–$61B Annual Crisis

Underground utility strikes cost the U.S. economy $30B–$61B annually (CGA DIRT Report). Our GPR technology maps subsurface infrastructure before the first backhoe arrives.

📈

Our Forecast · 90% Reduction by 2030

If drone-based pre-scan technology like DRONOTICS is adopted industry-wide, the CGA projects up to 90% reduction in underground damage incidents by 2030.

Beyond Archaeology · 5 Fields That Need Ground Truth

Utility Detection

Upgrade 811 "call before you dig" with pre-scan drone surveys

Construction

Safe site surveys before breaking ground on any project

Environment

Subsurface contamination mapping without invasive drilling

Disaster Response

GPR already locates survivors in collapsed structures

Mining

Innovation Project · Design Iterations

"We don't lose. We either win or we learn."

Iteration #1 · Power Source

Battery → Hydrogen → Hybrid

What Happened: Battery-only couldn't sustain full-sensor flight. We explored solar, then researched hydrogen fuel cells — but discovered they aren't widely available for real-world field deployment.

Researched & Rejected

Hydrogen fuel cells — scientifically sound, not field-viable. We documented why and moved on.

The Fix

Hybrid battery + gas engine — 40-min runtime, fully field-deployable.

Iteration #2 · Sensor Selection

HSI vs. Dual-Frequency GPR

What Happened: Initially considered Hyperspectral Imaging (HSI), but discovered it was surface-only and too expensive ($25k+).

The Fix

Switched to Dual-Frequency GPR ($2.2k) — sees underground, fits our budget, validated by Dr. Seegmiller.

DRONOTICS V1 — Cardboard Prototype

Version 1 · $45,000

Cardboard prototype — wrong sensor, over budget, didn't work

DRONOTICS V2 — Future Tech Drone with GPR

Version 2 · $9,000

Carbon fiber, dual GPR — expert-validated, field-ready

Failures = Innovation

"We don't lose. We either win or we learn."

Failure #1

The "Drifting" Turn

What Happened: Our initial Gyro turns were inconsistent. The robot would overshoot the target angle due to motor coasting at high speeds.

The Fix

Implemented "F1 Deceleration Logic" (30% speed -> 10% snap) to eliminate drift.

Failure #2

Attachment Overload

What Happened: We started with 13 unique attachments. Swapping them in the launch area took 40% of our match time.

The Fix

Designed a "Master Tractor Base" with just 6 multi-mission modular arms.

Failure #3

Power Source Iteration

What Happened: Battery-only power couldn’t sustain full-sensor flight time. We explored solar, then researched hydrogen fuel cells — but discovered hydrogen isn’t widely available for real-world field deployment.

Researched & Rejected

Hydrogen fuel cells — scientifically sound, but not widely available in field conditions. We documented why and moved on.

The Fix

Hybrid battery + gas engine — maximizing flight runtime while staying field-deployable. Best of both worlds.

Failure #4

Sensor Pivot: HSI vs. GPR

What Happened: Initially considered Hyperspectral Imaging (HSI), but discovered it was surface-only and too expensive ($25k+).

The Fix

Switched to Dual-Frequency GPR ($2.2k) to see underground and fit our budget.

Mentoring FLL #3054

Collaboration with "Lego Blasters"

We exchanged innovation project details with Lego Blasters #3054, learning from their research while sharing ideas they used to enhance their own solution.

Junior Robogineer Program

To ensure team sustainability, we integrated a 2nd-grade apprentice into our workflow. This "Junior Robogineer" learns FLL Core Values and basic mechanics alongside us, preparing the next generation of innovators.

Field Research — At the Archaeologist's Office

Team with Dr. Seegmiller at Tall Grass Archaeology

We visited Dr. James Seegmiller at Tall Grass Archaeology LLC — seeing months of hand-drawn field records firsthand. His office visit changed our entire sensor strategy: from a $25k medical sensor to a $2.2k dual-frequency GPR that actually penetrates soil.

Publishing Everything — So the Next Team Starts Ahead

We publish every failure, pivot, and fix at robogineers.com — because the best way to advance the field is to share what didn't work, not just what did.

Core Values · Inclusion

Different Ages.
One Team.

We integrated a 2nd-grade apprentice into our workflow all season. He built alongside us, asked hard questions, and reminded us to explain our engineering clearly enough for anyone to understand.

"He asked why we didn't just use a bigger antenna. We had to explain the physics. That made our whole team think harder."
