Envoy AUV
Product descripton: Envoy AUV by Cellula Robotics
The Envoy AUV, previously known as the Solus-LR, is a long-endurance underwater vehicle powered by a fuel cell. It can remain submerged for months, traveling thousands of kilometers. Using a suction anchor, it secures itself to the seabed for covert, long-duration missions in challenging underwater environments. This enables persistent surveillance and data collection, making the Envoy AUV valuable for a wide range of underwater applications, from scientific research to national security.
