Project Description

Underwater inspections and interventions are essential to maintain critical infrastructure. Currently, human divers take on the responsibility despite facing serious or lethal risks, especially in rough waters. Although robotic solutions exist, they either lack robustness in relevant metrics required for rough waters or require cost-intensive, polluting vessels and infrastructure.

In response to this challenging need, the Tethys Robotics team is developing an innovative compact underwater drone capable of autonomous mapping and survey even in strong water flows and poor visibility, finally enabling robotic automation in all waters. This complex but highly modular underwater drone offers autonomous inspections, produces high resolution 3D models of submerged infrastructure, and supports physical interactions with the environment. With safe, efficient, and cost-effective underwater operations, this technology allows streamlined inspections and predictive maintenance of critical infrastructures while, most importantly, protecting divers in life-threatening situations.
