The system operates based on a very simple principle: two large wheels, each containing pendulums that rotate around a central axis. By shifting the pendulum, the center of gravity of the wheel moves, causing the wheel to roll in order to regain balance. The wheels are watertight, allowing the entire unit to float.
Inside the wheels are the pendulums, which house the batteries and motors.

The propulsion is electric, and all potentially contaminating components are enclosed within the wheels.
Over time, the central body of MAR has been reduced in size and equipped with a ridge for mounting sensors and actuation tools, enabling its use in specific application fields.

Amphibious Version
The amphibious version of MAR is designed to operate in aquatic environments and is equipped for detection, monitoring, and inspection tasks. The vehicle’s wheels can be fitted with paddles to provide propulsion in water. The wheels themselves are buoyant and serve as the primary means of propulsion, while also protecting the payload from the surrounding environment.
The vehicle has a low center of gravity, ensuring stability and the ability to automatically return to its original position in case of overturning.
Additionally, MAR can operate in adverse weather conditions where aerial drones are unable to fly.
