–15°C
It arrives cold.
A typical delivery loses 15–25°C between the café and your door. Espresso becomes bitter. Pour-over becomes flat.
Meet Caffnaut — the first delivery robot that brews your coffee while it's on its way to you. No more lukewarm deliveries. No more stale espresso. Every cup arrives at peak temperature, peak aroma, peak flavor.
A collaboration
Tim Nixon's obsession with the craft of coffee meets Ottonomy's world-class autonomous robotics. Caffnaut is a purpose-built Ottobot — a proven L4-autonomous delivery platform with a custom Tim Nixon brewing compartment — designed to make the last mile the best mile for your coffee.
The problem
By the time your delivered coffee reaches you, it's already past its prime. The last mile is where great coffee quietly dies.
A typical delivery loses 15–25°C between the café and your door. Espresso becomes bitter. Pour-over becomes flat.
Coffee held for 20+ minutes over-extracts in the cup. Oils separate. Aromatics vanish. You drink the memory of a drink.
Cafés lose repeat orders over delivery quality they can't control — even when the beans, the barista, and the recipe were perfect.
Meet Caffnaut
Inside Caffnaut is a precision brewing chamber engineered by Tim Nixon, synchronized with the robot's ETA. Extraction starts the moment Caffnaut leaves the café — and finishes seconds before it reaches you.
ETA-aware extraction — grind, bloom, pour and crema all timed to your arrival.
Active hot & cold chambers hold each cup within ±2°C — hot brews stay 90–95°C, cold brews stay 4–6°C.
Caffnaut brews with the café's own beans and barista-tuned profiles — grind, ratio, temperature, bloom time. The craft stays yours; we just deliver it properly.
Each cup is dispensed into a unique, sealed vessel with a one-time access code. Spill-proof, contact-free.
How it works
Place your order through the café's app or our Caffnaut kiosk. Pick hot, iced, or spec'd to your taste.
Caffnaut autonomously departs and locks in its ETA. The brew engine syncs to the route.
Grinding, blooming, extraction — all performed mid-route. Thermal vault holds the cup at perfect temperature.
Caffnaut arrives, you unlock your compartment with a one-tap code, and drink coffee at its absolute best.
Built on Ottobot
Caffnaut inherits everything that makes Ottonomy's Ottobot trusted by hospitals, airports and enterprise campuses worldwide — and adds a café on top.
Fully driverless navigation, indoor and outdoor, with V2X integration for elevators and doors.
Real-time environmental understanding — sidewalk, lobby, corridor, curbside. It adapts.
Rain, heat, cold. Your espresso doesn't care and neither does Caffnaut.
Runs on Ottumn.AI — the cloud platform that orchestrates fleets of robots, drones & smart infrastructure.
