Stevens SD Group 6 AUV

On the control system

mjsamaan — Thu, 16 Oct 2008 22:53:22 +0000

Thanks to the Center for Maritime Systems (aka Davidson Lab), we have a microprocessor we are using to get things going. The TS-7200, with 2 serial ports, 2 usb ports, a 200 MHz arm processor, and under 2 Watts usage is a feasible solution, something we can at least start up on. Thanks to Dov Kruger, we may be able to use the TS-7300, which is light years better. With 10 serial ports, and an fpga programable hardware layer, this board leaves plenty of room for growth. As for now, we are developing basic scripts to load devices properly (so far a USB memory stick and a three-axis accelerometer donated from Honeywell to Dov).

Thats the update with controls so far, more to come.

Today’s meeting was held in Davidson’s lab. The group discussed the power consumption, battery set up and some issues regarding the design of the AUV.

It seems that the most up to date design has a series of flaws, mainly with the location of the thrusters. Also the stability of the AUV was another concern that needed to be changed in the final design of the AUV.

The power subsystem group is meeting with Edward Birshards on Thursday the 9th to discuses some design idea for the power system.

Also the microprocessor team is going to start work off of the micro processor board that is beeing donated by Dov.

Solidworks Design

Check out this intial Solidworks Design – definetly some tweaks to be done, but a pretty cool start

Mechanical Team Report

Venkat Rao — Thu, 25 Sep 2008 15:37:25 +0000

Hi,

I am Venkat and I work on the mechanical aspects of the project.

The Mechanical team needs to work on three reports for this semester. Here is the first one.

In this report we discuss the competition, the impact of the competition and our plan to win it.

Phase I Report

Discussion with Geoffrey Lake

auvg6 — Wed, 17 Sep 2008 16:15:13 +0000

This past Sunday, I had a 30 min conversation with Geoffrey Lake picking his brain about how he managed his Best New Entry Team at University of Colorado Boulder. After giving me a much better idea of what we were getting into in terms of cost and organization, he emphasized three things:

Perfection is the Enemy of Good Enough
Love your project, it’ll show and motivate others
and KISS – keep it simple stupid

On a more technical side, he gave us tips on seals, design, and software.

I have to say he was extremely helpful and nice, willing to answer questions and offered to let us contact him with any other questions. Thanks Geoffrey!!

Today was the first meeting with our new members of team from Mechanical Engineering.

We analyzed and distributed the basic project work load among the team members.

AUV:

Hull Design – Venkat, Abdul, Wan –> Contact Raju Datla, Alistar Greig

Propulsion – Jon, Mike –> Contact Raju Datla, Alistar Greig

Central Control – Mina, Max –> Contact Haibo He

Power & Sensor – Freddy, Nikul –> Contact Blicharz

On the side note: for sensors we would like to research and understand are as follows:

-Sonar (for Distance)

-Image

-pressure

-IMU (for Compus and Accelarometer)

-Hydrophone ( goes with Sonar)

-Moisture

Today we met with our official adviser, Haibo He. This is what we determined

Next step is to develop specific system designs – clarifies what we will need
Start identifying parts (that we can hopefully get sponsors for)
Weekly Adviser Meetings will be on Thursdays at 2:00 pm

In addition, we reached out to the mechanical engineering department. After talking with Gonca Altuger, who is the head TA for mechanical engineers, we identified two loose students and a team of 5 who were doing underwater propulsion. After meeting them in class, the group of 5 was very interested and were scheduled to meet as a group of 9 on Tuesday, after I speak with Geofrey Lake (University of Colorado).

After class, we went to meet with Dov Kruger at Davidson Labratory. In this meeting Dov made it clear to us that the best way to get funding was to enter a competition, specifically AUVSI. After some research and the initial overwhelming feelings, the group became excited to proceed, knowing that a large task remained ahead.
