a brand of UAV-DEV GmbHSensorBoat Multi-Sensor USV
Unmanned autonomous boat with redundant propulsion, open ArduPilot control and generic payload mounts for echo sounders, multibeam, side-scan, water samplers or your own sensors. Made in Germany.
Technical data →Maritime robotics from Bremerhaven, Germany
Bathymetry of what lies beneath the surface.
With the SensorBoat, a boat you can also fit with your own sensors.
Mare Robotics is the maritime brand of UAV-DEV GmbH. We build the SensorBoat, an autonomous boat with 10 kg payload, survey your waters with it and deliver the depth map. We also sell sonar technology from Cerulean Sonar. Everything from one source, with support in German and English.

SensorBoat · Sand pit · June 2026
Hydrographic survey
Depth maps and 3D models of the bottom for sand pits, harbours, basins and lakes, including volume calculation, contour lines and side-scan imagery. You receive finished data in your format.
Services and reference →Cerulean Sonar
We sell imaging sonars, multibeam echo sounders, DVLs and positioning systems from Cerulean Sonar. Every purchase through us includes initial setup support, remotely and in German or English.
Product overview →SensorBoat
A boat that carries your sensors and drives itself.
Four T200 thrusters make the SensorBoat omnidirectional: it holds position and heading independently, runs survey lines with RTK accuracy and returns home even with two thrusters down. Payloads are fastened, cabled and sealed through 20 generic mounts. The adapter comes out of a 3D printer.
- 1.5 kWh LiFePO4, about 12 hours or 34 km per charge
- Autonomous missions with live video, pause and resume, mission upload while under way
- Control and record live depth and side-scan from the shore
- 4G/5G data link with backup, 360° laser scanner for obstacle avoidance
shallowdeep· Depth model of a sand pit, June 2026
Survey as a service
Depth maps and 3D models of the bottom.
We run the SensorBoat on your waters, capture the bottom with a multibeam or single-beam echo sounder and deliver processed data: depth grid, contour lines, 3D mesh, volume and report. On request combined with a drone orthophoto of the shoreline.
- Sand and gravel pits: remaining volume, extraction progress, slopes
- Harbours, berths, locks: target depths and sedimentation
- Retention basins, reservoirs, treatment plants: silting and sludge levels
- Side-scan for object search, wrecks and structure inspection
Authorised distributor
Cerulean Sonar: sonar technology that fits small vehicles.
Cerulean Sonar develops compact imaging sonars, multibeam echo sounders, Doppler velocity logs and acoustic positioning for ROVs, AUVs and USVs. We sell these sonars as a distributor for Germany listed by Cerulean. Buying from us includes initial setup support, and you can reach us in German or English. On request we integrate the devices directly into the SensorBoat.

About us
Mare Robotics is the maritime brand of UAV-DEV GmbH.
UAV-DEV GmbH from Bremerhaven, Germany, develops and manufactures unmanned systems in the air and on the water. Under Mare Robotics we bundle everything to do with waters: the SensorBoat, survey missions with our own equipment and staff, and the sale of Cerulean Sonar products.
You talk to the people who designed the boat and operate it on the water themselves. Adapting it to your sensor or use case is our normal business, not the exception.
