The DIP project is part of a longer-term research collaboration to convert a RHIB vessel into an unmanned surface vessel (USV) in two phases, with the first phase resulting in a remotely operated vessel and the second stage in an autonomous surface vessel (ASV).
Stage 1 resulted in platform development and integration including:
- USV control components including the steering system, engine and vessel instrumentation, host computer, inertial measurement system and communication systems.
- Sensors including radar system, LIDAR system, windspeed sensor, and cameras.
Stage 1 also involved algorithm development including:
- Model prediction control system
- Path planning
- Marine systems simulator
- Optimal control based guidance system
The University of Adelaide team is using machine learning techniques to identify the range and profile of waves ahead of the vessel using the stereo camera system – and along with measurements from the vessel’s other sensors, this will provide a more accurate profiling of oncoming waves.
The next stage is to convert the vessel to autonomous operation.
The work conducted to date has attracted industry interest. Further projects with industry partners are under discussion to continue this work into the future.
