1999 Projects: ROV improvements

Precision-control technologies for underwater vehicles

Project lead/manager: Steve Rock (adjunct)
Project team: David Clague, T. Craig Dawe, William Kirkwood, and Rob McEwen

The goal of this effort is to explore high-risk technologies that could potentially enable a wide range of autonomy in controlling autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs). At one end of the spectrum of autonomous activities are pilot aids for ROV operation, such as automatic stationkeeping, point-and-click manipulator control, and automatic generation of mosaic (small seafloor maps). At the other end of the spectrum is the capability for fully autonomous AUV missions and for ROV tasks that do not require the full creativity of a human pilot.

The immediate focus of this project will be in two technology areas. The first is the development and demonstration of automatic, vision-based feedback control, where the computer utilizes the camera to perform a control task involving the vehicle or the manipulator. This frees the pilot to do other tasks. The second area of endeavor is the development of techniques for high-performance, task-level control (e.g. point-and-click) of manipulators that operate either from a fixed base—such as an ROV on the seafloor—or from a small, free-floating AUV.

An additional goal of this program is to provide a path through which scientists, engineers, and pilots at MBARI can influence doctoral-level research at Stanford University, such that new technologies can be explored that are of interest to MBARI but considered too high-risk for near-term development. This arrangement will also allow interested scientists, engineers, and pilots at MBARI to implement, test, and evaluate new concepts developed at Stanford.
