- The first wet test of RUAUV was performed on friday (18.12.2009) - see video below.

- The team has finished its report which is available for download from here.

- The team also gave a presentation on RUAUV on friday and it is available for download from here.

Many components have been ordered and some have arrived.

- The thrusters arrived on monday.

- The battery charger arrived on tuesday.

- Propeller Servo Controller USB and five (one for each thruster) Devantech MD22 motor controllers were ordered and they arrived today.

- DCDC-USB DC-DC converters that will regulate the voltage from the battery packs were ordered today and will hopefully arrive sometime next week.

- Work on building the battery packs has begun and will hopefully be completed today or tomorrow.

- The end-cap for the pressure vessel has been designed and is being made for us.

A lot has happened in the passed few days.

- The team went on a visit to professional diver Árni Kópsson who showed us his ROV camera (pictures in the media section).

- There was a change with the hard drive, instead of getting a 32 GB one we upgraded to a 64 GB drive as it was at almost the same price and had a much shorter delivery time, it arrived earlier this week.

- Most importantly: the components of the frame have been built and the frame itself assembeled, as can be seen in the picture below (more pictures in the media section)

Today the thrusters and a charger for the batteries were ordered. A crude timeplan with specific tasks for all members of the team was drawn up.

Gísli, Kári and Lahcen went on a shopping trip today with Gísli Freyr where the following items were bought and/or ordered:

 

- 84 x 4000 mAh NiMH size C batteries

- The plexiglass tube housing for the electronics

- The side plates of the AUV as well as the mounting plates that go under the plexiglass tube

- A Fit PC without a hard drive

- A 32 GB SSD for the Fit PC

 

Kári also drew up an idea for the battery packs which can be seen below

A decission was reached on using the Seabotix BTD150 thrusters for the AUV. They have a depth rating of 150 meters which is a lot more than what will be required as well as being at a reasonable price.

Below you can see the latest design of the AUV. The thinking is to have the sides made out of black 16 mm POM plates where we can drill holes at different places to test different thruster setups. When the final positions of the thrusters are determined we either cut away all unnecessary parts of the plates, i.e. all areas that are not significantly contributing to the structural integrity of the AUV, or we simply have new plates cut for us.

 

The main idea was to have the assembly/disassembly of the AUV as simple and as fast as possible. This was achieved by minimizing the amount of components and by only using bolts and nuts to fasten those components together, i.e. no components are welded or in any other way permanently fastened to each other. This also makes replacing components a lot easier.

Work on the site begins, the basic skeleton (as well as the look) is ready so the next thing on the list is to put some meat on those bones.
