The new mechanics is now assembled and initial test has been performed with good results. After that the vacation period here in Sweden is ended we will test the new prototype in a real pool to verify the first test results. The work with the electronic hardware and the software continues. We have been offered to apply for an extension of the time schedule to the end of September. That gives us a lot better possibility to finish the project with successful test results. Integration with the software can be started when the hardware tests are trough. The integration will be made in several steps. After finish one step and before we start next step in the integration process we plan to test integrated functionality under real test conditions in pools. We estimate to start integration in the beginning of September. 

We have still not been paid for the work we did in year 2011 by EC! Anyway we continue to work with the development of the hardware, software and mechanics. Due to bad test results of the locomotion and traction capability of the robot we have redesigned the mechanical configuration and hope for better results in next test. We have got approval for extension of the time schedule to the end of July. Anyway it will be very tough to finish the project in time.

Electronic boards specifications are ready and the electronic design have been started.

Most of the critical components for the navigation system have been procured. Mechanical and electronic integration is well on way and the electronic design specification is close to ready.

The project have now been able to sort among all technical possibilities there are to navigate under water and concluded a method for triangulation and range finding. Several weak points have been identified for the alternative solutions we have tried so far.

A mechanical prototype has been built and is now almost ready for tests in real pool environments.
