Tethra is a prototype autonomous underwater vehicle (AUV), designed at
the University of Limerick, to carry out research in underwater robotics and
control. The vehicle adopts a behaviour-based control paradigm. In this paper
we report on the design of the Tethra test platform and the embedded controller
development for investigating classical and more advanced control approaches.
The Tethra test platform includes the development of AUV simulator, which is
used as a foundation for off-line controller tuning and testing.
