Operating an autonomous underwater vehicle (AUV) in close proximity to terrain typically relies solely on the vehicle sensors for terrain detection, and challenges the manoeuvrability of energy efficient flight‐style AUVs. This paper gives new results on altitude tracking limits of such vehicles by using the fully understood environment of a lake to perform repeated experiments while varying the altitude...
A current challenge for AUV missions is to combine long endurance with high manoeuvrability. The proposed Pipefish AUV is a long endurance AUV capable of high quality survey missions that can deliver multiple hover capable AUVs to sites of interest. The Pipefish AUV and the small vehicles can perform cooperative tasks and reach remote locations without the need for a monitoring surface vessel. It...
Photographic surveys of the seafloor with flight style autonomous underwater vehicles are a very effective tool for discovery and exploration. Due to the high terrain collision risk for the survey vehicle, they are employed with caution. The extent of this risk remains unquantified. For mission planning, researchers and vehicle operators have to rely on their experience. This paper introduces measures...
