Building the ROV Controller: Prepare the Box: Begin with a compact box measuring 12x5x9 (LxBxH) that comfortably fits in your hand. Drill four holes on the top side of the box with a diameter matching that of your momentary buttons (in this case, 16mm). Drill two additional holes on the upper side.

12. Add a mount for the camera: glue the half of a pipe on the front of the hull and screw the fixation of your camera (see the picture). 13. (Optional) Glue a T shaped 32mm diam. coupling at the rear of the hull (the Eternet cable will pass through it).
- The Frame. This was an easy choice. Looking to see what other folks had done pushed me in the direction of 1/2 inch PVC pipe. It's cheap and easy to work with.
- The Dry Tube. First pic is the buoyancy test. Second pic attempts to show how thruster wires are led into potted bullet connectors. Third pic is more of the same plus the additional bump for potting depth meter and its wires.
- DIY Thrusters. I got a lot of ideas from the web and decided to go with bilge pump cartridges. They're relatively cheap (about $20+) each and have about the right amount of torque and speed.
- Tether. I used a 50 foot length of Cat 6 Ethernet cable. I pushed it into 50 feet of polypropylene rope. I used the end of a ball point pen taped onto the cable and took about an hour pushing it through the rope.

In this project you will build your own small ROV using a plastic food storage container and an Arduino. The project instructions will provide you with the basic design, parts list, circuit diagram, and code to build a simple ROV with two motors. You will use an integrated circuit called an H-bridge to control the motors.
Figure 2 shows a ROV robot. Autonomous underwater vehicles (or AUVs) are controlled by computers on board the robot, and can operate without being connected to the surface. Because both ROV and AUV robots contain computers and electronic equipment, underwater robots need to be waterproof. This means that water cannot damage the equipment ...
