Evologics SONOBOT 

Autonomous Unmanned Surface Vehicle for Hydrographic Surveys

With carbon fiber hull construction and water jet propulsion, the SONOBOT's catamaran design offers an ultra-stable,  ruggedized platform for surveying and data collection.  Check out our video and specs to learn why SONOBOT  is the smartest ASV on the market today. The autonomous EvoLogics SONOBOT is a smart, lightweight surveying solution for harbors and inland waters.

Design objectives: Usability, robustness and versatility, paired with high-performance of the on-board sensors.

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.

SONOBOT includes an advanced single-beam echo sounder enabled with EvoLogics patented S2C broadband communication technology.   The platform is capable of delivering precise and accurate depth measurements even in very shallow waters.


Optional side scan sonar, GPS system and other sensors are 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.
