Autonomous Hydrographic Survey
An unmanned autonomous surface vehicle with high usability in mind, the autonomous EvoLogics SONOBOT was developed to provide surveyors, service providers and researchers with a smart lightweight solution for hydrographic surveys and other applications in harbors and inland waters.

Technical data:
  • Length: 1320 mm, width 920 mm, height 450 mm
  • Weight 30 kg
  • Speed up to 6.4 knots
  • 10 hours of battery operation
  • 32 GB for local storage
SONOBOT design objectives were usability, robustness and versatility, paired with high-performance of the on-board sensors.

SONOBOT is a small, simple and usable platform for planning and executing a hydrographic survey that can deliver accurate geo-referenced bathymetric measurements and high-quality imagery with minimum transport, launch and recovery efforts.

Specifically for the SONOBOT, EvoLogics utilized the patented S2C broadband communication technology to build an advanced single-beam echo sounder, capable of delivering precise and accurate depth measurements even in very shallow waters. The side scan sonar, GPS system and other equipment options were pre-selected among commercial off-the-shelf products to best fit the SONOBOT platform and offer the user the best configuration for his particular requirements

A system consists of
  • 2 float hull with built-in water jet system and battery
  • Waterproof hull with computer, antennas and HD camera
  • Sonar (single beam) from 0.5m to 60m depth radio Control
  • Land station with antenna with GNSS 2 with high gain
  • Transport boxes for the entire equipment
  • Data transfer to land station via WiFi
  • Spare parts and tools
Sonobot system
Sonobot - search with sonar
Sonobot - Depth measurement
Hydrographic survey - Bathymetry and seafloor imaging in ports, harbors and inland waters
Survey missions Exploring shallow waters, natural reserves, restricted or hard-to-reach areas
Search and recovery Locating archeological artifacts, wrecks
LBL calibration - A Sonobot with built-in S2C R USBL Transceiver is a great solution for calibrating the baseline of an LBL positioning system
Monitoring - Regular examinations of underwater infrastructure
