The MicroAUV2 is the result of further development of the MicroAUV. Besides the advanced propulsion system, the MicroAUV2 is able to compensate buoyancy. Together with the huge amount of sensors, this platform is used for the evaluation of marine control strategies in combination with behavior-based control approaches from artificial intelligence.

Currently, several students activites are in progress concerning the enhancement of the autonomy of the MicroAUV2 in terms of energy supply, communication, and adaptive self-learning control strategies.

With the incorporation of a camera system together with the use of the digital signal processor and the FPGA, the MicroAUV2 can be used for evaluating underwater vision algorithms.
