A bolt on the deck costs an engine. The debate is who picks it up and how often.
our FOD-clearance robot sweeps flight decks autonomously with obstacle avoidance. Essential Aero and SkyAutoNet both publish detailed figures for airfield FOD robots, which makes this a comparison a buyer can actually run.
The robot is built for working flight decks rather than for a demonstration apron, and it is sustained in-region by the team that delivers it. Sweeping the deck is a routine that has to survive daily operations, not a one-off trial.

What the table means
Both competitors publish more than we do, and the numbers are good
Essential Aero gives endurance, charge time, speed, gradient, temperature range and the size band of debris collected. SkyAutoNet gives a detection rate against a stated object size, the three collection mechanisms and the loading volume. Those are the figures a deck officer would ask for, and any tender should hold us to the same disclosure.
A carrier deck is not a runway
Runway robots work a long, flat, uncontested surface on a predictable schedule. A flight deck is short, crowded, moving, and full of people and aircraft doing something more important than debris clearance. Obstacle avoidance and deconfliction with deck operations matter more there than sweep rate. Our system is specified for flight decks, which is a narrower and harder problem than the airport case both competitors describe.
Where the sweep data lives
Both published competitors route data off the platform: one to a vendor cloud with analytics and reporting, the other over 5G or LTE to a control station. For a civil airport that is convenience. For a naval deck it is a sortie-rate signal leaving the ship. A non-aligned supplier with in-region sustainment can keep the data path inside your own network, and that should be written into the contract rather than assumed.
Questions buyers ask
What is the best alternative to the Essential Aero FOD-BOT for a military airfield?
FOD-BOT publishes a strong civil and airside package: up to 6 hours per charge, 2.5 m/s, 26.5 degree gradient, ultrasound and LiDAR avoidance, debris from 0.02 to 8 inches and a cloud fleet layer. Our FOD-clearance robot is built specifically for flight decks and comes from a non-aligned supplier with in-region sustainment, which matters when the data path and the support chain have to stay national. We publish fewer figures today, and a serious tender should force us to state them.
How does an autonomous FOD robot compare with a manned FOD walk on cost?
The comparison is people-hours against capital. SkyAutoNet cites roughly 13.9 billion US dollars of annual global losses from FOD and notes that air forces and navies mobilise large numbers of personnel for FOD walks before and after flying. The robot removes that recurring labour and works at night. Ask any supplier for sweep time per 1,000 square metres and availability rate, then compare against your actual manning cost.
Can a FOD-clearance robot operate on a moving flight deck rather than a runway?
That is the distinction that matters. Both published competitors describe airport runways, taxiways and aprons. Our system is specified for flight decks, with autonomous navigation and obstacle avoidance in an environment full of moving aircraft and crew. Whichever supplier you shortlist, insist on a trial during actual deck or flight-line operations rather than on an empty apron.
Where does the detection data go, and can it stay on our network?
Essential Aero routes data to its own cloud ecosystem for analytics and reporting; SkyAutoNet transmits over 5G or LTE to a control station. Both are reasonable for civil airports. For a naval or air force customer, sweep frequency and timing are operational information, so require an on-premises option in writing. Our model is in-region sustainment from a non-aligned supplier, which makes a national data path straightforward to contract for.
