Archaeology is a race against time. We use LiDAR & Dual-Frequency GPR to unearth history before it is lost forever.
Robogineers — Iowa State Champions · International Qualifier

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
"Wasting time in the wrong areas"
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:
Blind digging destroys fragile history before it can ever be mapped or protected.
Undetected subterranean voids pose immediate safety risks to the field crews.
Unnecessary trial pits ruin local ecosystems and native soil composition forever.
Manual labor currently consumes months of budget on empty dig sites.
Visualizing the Challenge
DRONOTICS · Precision Remote Sensing Ecosystem
Penetrates dense jungle canopies to generate 3D bare-earth topography, revealing hidden ruins unseen for centuries.
Ground Penetrating Radar detects buried masonry and subterranean density anomalies without disturbing a grain of soil.
Coordinate-syncing sensor hits to a global grid for layered, high-precision digital site documentation in real-time.
Custom computer vision models trained to identify artifact shapes and construction patterns automatically during flight.
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
Upgrade 811 "call before you dig" with pre-scan drone surveys
Safe site surveys before breaking ground on any project
Subsurface contamination mapping without invasive drilling
GPR already locates survivors in collapsed structures
Plan safe excavation paths before any digging begins

Innovation Project · Design Iterations
"We don't lose. We either win or we learn."
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.
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.
Version 1 · $45,000
Cardboard prototype — wrong sensor, over budget, didn't work
Version 2 · $9,000
Carbon fiber, dual GPR — expert-validated, field-ready
Finally. You are the first team to actually have heard the call.
Dr. Patricia Jubinska
Archaeologist · Union Institute & University / Harvard · Tor Castle Project, Scotland
Consulted for 6 FLL teams. We were team 7. She has a site in Scotland — waiting for our solution.
Jimmy 2.0 · "Reliability Through Scientific Iteration"
Bulky Base / 13 Attachments / Inconsistent Heading

"Inspired by Formula 1 cars braking for an apex, we drive at max speed for 80% of a turn, then engage precision PID snapping for the final 20%."

"We don't lose. We either win or we learn."
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.
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.
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.
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.
From First Sketch to Ground Truth
GroundSight fuses GPR and LiDAR into a live 3D site map — built by our team. Watch it scan in real time. Every detection geo-tagged to the cloud. No shovel required.
Sharing Our Knowledge
We exchanged innovation project details with Lego Blasters #3054, learning from their research while sharing ideas they used to enhance their own solution.
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.
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.
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.

Combining both survey abilities in one unit would be quite innovative... Good luck at the International Championship!
Dr. Patricia Jubinska
Archaeologist · Harvard / Scotland
Great work and passion. Love to tool up some LiDAR data from the Effigy Mounds in Iowa. This is free data on the USGS website.
Vance & Owen Pieste
Open House Visitors
We are super excited to see your project! Don't be afraid to make changes when things can be improved.
Paul & Robin
Open House Visitors
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."
Discovery Beyond the Dig
6 Specialists. One Ground Truth.
Motor & Power
"I engineered the torque formula that made Jimmy 2.0 possible."
Drone Expert
"Every failure, every fix is published — so no team starts from zero."
LiDAR Expert
"One LiDAR survey found 61,000 Maya structures in 4 days."
Antenna Expert
"Our points-per-second spreadsheet changed how we think about strategy."
Camera Expert
"Zero false sensor triggers in 50 runs. That's not luck — that's calibration."
GPR Expert
"We had the wrong sensor. We fixed it. That's engineering."
