About

About Otter

Otter is Maritime Robotics' compact electric USV for hydrographic survey in sheltered and coastal water. The vessel separates into portable sections weighing less than 20 kilograms for transport, assembly and shore-side launch.

Maritime Robotics specifies up to 20 hours of operation with modular survey payloads. Endurance, bathymetric accuracy, speed and operating area depend on sensors, sea state and mission configuration.

Specifications

  • Endurance H: Up to 20 hours
  • Section Weight Kg: Each modular section is under 20 kg
