Update on Senior Project Autonomous Boat

Hello Everybody,

I have since picked up a partner named Sam to help me...The boat is now going to have a wireless fish-finder besides sonar.

Here is an update my Autonomous Boat project. I bought the APM 2.5 board with the U-Block LEA-6H GPS, and downloaded the mission planner software. I was able to get the APM 2.5 board to communicate with the mission planner program, and the GPS was able to hone in on where I was located at. It seemed to be pretty accurate (hopefully within 3meters) from what I could tell from moving around.  I have a ordered a Brushless_Inrunner DC motor along with a HobbyKing SS Boat Series 70A ESC (sites below)

The batteries I am using is 7.4V Lipo-Cell battery packs and will build a circuit with a voltage regulator to bump the voltage down to 5V to the APM 2.5 board.

We built a female mold out of particle board and auto-body putty. Then used fiberglass to build the hull of our boat based off of the semi-displacement hull we designed in DelfShip (a free program to download). The mold is done and we just started to fiberglass the boat about 3 layers for strength. We are at the point now to remove the fiberglass from the mold we, but are running into trouble getting the fiberglass out of the mold (its suck in), so we may have to break the mold to get the boat out.

I have attached the overall block diagram, DelftShip hull design, and a picture of our jet drive to drive our boat. I will add another discussion shortly with wiring diagrams, and a 3D CAD version of the boat to better see the project.

Soon my partner and I will have to program the APM 2.5 in accordance with the mission planner to get the the boat to move to the way-points chosen.

Any input, questions, or advise it welcome!

-Thank you

    @Bobby,

    You didn't use mold release prior to starting to lay in the fiber glass?
