Revolutionize Underwater Work

ALL WATERS Enter any water, regardless of currents up to 2 m/s

PERCEPTION Allow zero visibility mapping at high resolution [cm]

COST EFFICIENT Operate at up to 10% of the today's cost

100% SAFE Exceed human barriers such as depth and limited dive-time
Fields of Application
Due to human limitations, robotic solutions are gaining traction by overcoming barriers in the areas of search & recovery as well as inspection & surveillance – a perfect opportunity for Tethys Robotics.
SEARCH & RECOVERY Dangerous jobs: Professional divers working in search & recovery risk their life in hazardous situations, especially in turbid rivers, when searching for missing people or lethal objects such as ammunition.
INSPECTION & SURVEILLANCE Today's problem: The assessment of underwater structures is done with costly equipment, and yet the data suffers from poor quality and is often inconsistent due to manual data collection. Inspection is often limited by strong currents and zero visibility
