A high-mobility, humanoid subsea robot engineered to replace and exceed the capabilities of professional divers. Its stable underwater operation and advanced control allow for precise inspection, observation, and monitoring of subsea infrastructure. It supports a wide range of missions such as debris removal, non-destructive testing (NDT), hull maintenance, rope cutting, object retrieval, and explosive ordnance disposal (EOD). ROBSTER is also built to function in radioactive subsea environments, making it a solution for nuclear facility operations.
