Both drives and swims: Mavka Technology has developed a terrestrial amphibian robot

The robotic amphibian drone BI34G from the Ukrainian company Mavka Technology was presented at the Brave1 Defense Tech Valley 2025 exhibition.

"Requests for the development of this drone came from special units of the Armed Forces of Ukraine. They wanted a ground-based drone that could conditionally travel 10 kilometers, enter a certain place, swim across a water obstacle, perform a certain action, and return," a representative of the development company told Defense.

The robot can carry up to 500 kg of cargo on its own and 1,500 kg in tow. The range with a full load is 20 km, the speed on land is 10 km/h, and on water is 15 km/h. The engine is electric. When crossing the river, the drone is propelled by water jets with a capacity of 24 kilowatts, like on jet skis.

The closed capsule allows it to be used for medical evacuation. The work includes fasteners for tensioning a net to protect the injured person from "drops" and FPV drones.

The company has been working on this project for the past year. The problem during development was adapting the robot to drive onto a high bank – in some places it could not get out of the water. Therefore, the team decided to install two tracks instead of wheels and develop a special suspension.

Now, when the amphibian drone drives onto a high bank at a high angle with its front track, the rear track does not hang in the air, but clings to the side surface of the bank, propping the machine up.

In terms of dimensions, the BI34G is just wide enough to fit into any minibus used by the military.

According to the developer, the basic version of such a drone will cost $25-30 thousand. The product is currently in the process of codification at the Ministry of Defense.

Previously, "Defense" wrote that at Brave1 Defense Tech Valley 2025, a ground robot with a 25-mm automatic cannon was presented, which should take over some of the functions inherent in infantry fighting vehicles.
