| Research Abstract |
The development of a control architecture for an autonomous underwater vehicle(AUV) is discussed. A simple mission, feasible in the ocean environment, is considered in order to allow the development of an architecture that can be implemented soon, and tested in the real world.
A number of control systems implemented in robots nowadays show a high degree of reactivity. They provide a more robust and viable operation in real-time than the traditional approaches that include a sequence of environment analysis, planning and execution. However, such reactive systems have been concerned with the execution of primitive actions like collision avoidance and low-level path planning.
We intend to investigate the implementation of high-level goal-directed tasks in a real-mission. A parallel object-oriented concurrent system based on hardware performance as well as the control structure of the vehicle. The software is intended to represent a group of experts that communicate among themselves through message passing. They form a cooperative system for mission planning and execution. This approach is aimed for an integration of reactivity and high-level goal-directed reasoning.
The development of this control system related to the problem of navigation and guidance near the sea bed is emphasized. A collision avoidance system based assisted by a grid map has been investigated, and some preliminary results of simulation are presented.
