The goal of this ROV is to go up and down, turn left and right, and glide through the water.

The Materials needed for this project are listed below:

Materials:

-Amazing Goop

-20 feet of wire

-3 rocker switches

-3 DC motors

-Small plastic box

-Battery pack

-PVC pipes

-Auto-Desk Inventor software

Tools needed:

-3D printer

-Drill

-Soldering iron

Step 1: Coming Up With a Concept and Printing

For my ROV concept I looked to space ships and underwater vehicles for inspiration. I focused on space craft because there was a wider range of ideas and designs than any current underwater craft. Throughout all of the designs I saw that each ship had a point at the front to pierce the water and a wide back part to help balance the boat. So I designed my ROV shell to have similar qualities. I started with a Y shape and expanded on the idea as the project went on.

I used auto-desk inventor to design the ROV. The file that I used is attached below. I used a maker-bot printer to print my design once it was complete. The print takes about six hours to print.

Step 2: Wiring

After designing my ROV, the next step is to wire the ROV. Along with the picture the schematic that I used for my wires will also be attached. The schematic and my wiring are very simple for this project.

Step 3: Water Proofing

Next step in preparing the ROV for the water is water proofing my motors and connecting them to my shell. For this part I cut three, one inch PVC pipes for my motors. The idea was that my motors would fit tight inside of the pipe so that they wouldn't move. After I put them all in I used Amazing Goop to secure the wires and keep the motors in place. I left the goop to dry overnight so that the glue would harder ans keep everything inside dry.

Step 4: Propellers

I used auto-desk inventor to design my propellers. I created a shaft in the middle and built off different planes to add the blades onto it. I then fillet the blades to make the more like cups so that could go through the water easier.

Step 5: Assembly

To assemble my ROV I just slid the motors into the holes that I had inside of the ROV. I used hot glue to keep the motors and the stray wires in place.

Step 6: Testing

After the propellers are attached, your ready to test this ROV. During testing the weight distribution was off so to help with that, I drilled holes in the front and then filled them with sand to add more weight to the front. This helped with the weight and made the ROV run smoother.

Step 7: Files

Here are the files for my ROV design and my propellers.
