After an earthquake or a flood, the map is the first casualty. Roads split, bridges drop, debris fields form where a street used to be, water mains burst and turn a district into a lake. Every route planned yesterday is a guess today — and the vehicles sent to help are each built for one kind of surface.
Earthquake
The problem
A collapsed span cuts the only access road. Behind it, three kilometres of rubble, then a district that is intact and cut off. A helicopter can overfly it and cannot land among the debris. A ground unit reaches the broken bridge and stops.
What BECCARII does
Drives to the break, lifts vertically over the span, lands on the far side — on rubble, because the tracked undercarriage is built for it and the tracks shield the propellers during touchdown — and continues on the ground. The obstacle costs ninety seconds instead of a re-routed convoy.
Domains: drive · VTOL · fly · swim
Flooding
The problem
The one scenario where ground and water alternate every hundred metres. A boat cannot cross the embankment; a truck cannot cross the water. Rescue teams end up carrying inflatables between stretches of dry ground.
What BECCARII does
The hull is sealed and amphibious. It drives the road, swims the flooded section, drives out on the far side and lifts over the railway embankment if the underpass is submerged. No transfer between craft, no waiting for the right vehicle to arrive.
Domains: drive · swim · VTOL
Avalanche and mountain rescue
The problem
Snow, debris and frozen lakes: surfaces that carry a tracked vehicle and swallow a wheeled one. Landing sites are steep, uneven and change with the weather.
What BECCARII does
Flies over the valley, lands on the snowfield without a prepared site, and moves on tracks to the search area — with the endurance to stay, because surface movement costs roughly twenty times less energy than hovering.
Domains: fly · VTOL · drive · swim
Wildfire and industrial incidents
Access roads blocked by the incident itself, terrain that changes hour by hour, and a need to reposition repeatedly rather than fly one sortie. A machine that can land imperfectly, wait, and move again on the ground fits that rhythm better than one that must return to base to reset.
The pattern
Disaster response is not one hard problem — it is a chain of ordinary problems, each solvable by a different vehicle. The cost is in the seams: the transfers, the waiting, the re-routing. One machine that changes domain in seconds removes the seams.
Endurance
Flight is expensive; driving and swimming are roughly twenty times cheaper in energy. On the same budget BECCARII works about fifteen times longer on the surface than in the air — a deployment measured in hours on scene rather than minutes of hover.

Endurance and redundancy
Propulsion is distributed across eight independent electric units. Losing two of the eight does not end the mission — the vehicle lands safely on the remaining six. The propellers sit inside the tracks, which shields them from branches, debris and cable — precisely what a disaster zone is full of. The same track is landing gear on touchdown, drive system on the ground and obstacle-clearing geometry in between.
The architecture is covered by a granted patent family with priority of 7 June 2012, spanning more than 50 jurisdictions.
Frequently asked questions
What makes flood response different from other rescue scenarios?
It is the one case where ground and water alternate every hundred metres. A boat cannot cross a levee or a field; an off-road vehicle cannot enter the flooded area. Every switch between them costs a transfer.
Can it land on snow?
Yes. The tracks give a large contact area and low ground pressure, which is what allows a tracked vehicle to sit on surfaces that will not carry a wheeled one.
Can it reach a building cut off by water?
It can land on the roof, on the water beside the building, or drive in through shallow ground, depending on what the site allows.
What happens if two motors fail?
It lands safely on the remaining six. Redundancy is designed in, not added on.
