Introduction: Y-Wing ROV
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:
-20 feet of wire
-3 rocker switches
-3 DC motors
-Small plastic box
-Auto-Desk Inventor software
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.
