A bit about DOER

We design and build underwater vehicles

More about us

Building underwater vehicles is a fascinating and complex field that involves designing and constructing machines capable of navigating the underwater environment. These vehicles, ranging from small remotely operated vehicles (ROVs) to large manned submersibles, are engineered to withstand the immense pressure and harsh conditions found beneath the ocean's surface.

Our vehicles are used for deep-sea exploration, marine biology research, and even underwater archaeology.

The design of underwater vehicles often integrates advanced technologies in propulsion, navigation, and communication systems, enabling them to carry out a wide array of tasks, from scientific data collection to search and rescue missions. The development of these vehicles continues to push the boundaries of oceanic exploration, offering new insights into the least explored areas of our planet.

“Thank you DOER for this quality product, helping bridge man and ocean during our expedition.”

After thoroughly reviewing the global market for subsea robotic manipulators our team unanimously decided to purchase two of DOER’s Sea Mantis manipulators. Clearly, with the combination of effective cost, service, state-of-the-art technology and seamless integration to our submersibles the Sea Mantis became the perfect match. Our mission was of great importance to humankind, the objective; curing cancer, through the collection of deep sea coral which provides an “organic chemical” roadmap for scientists to study, thereby unlocking the oceans medicinal secrets humans have yet to discover. Thank you DOER for this quality product, helping bridge man and ocean during our expedition.
