How to build a ROV
UUR has developed their own ROV kit that students build in their after school programs. We recently switched to using a bilge pump motor, but suggest if you are building a ROV at home to use this supply list. This kit costs about $30 and uses common parts from a hobby and hardware store. We recommend using the SeaPerch.org ROV manual when building your ROV. There are other great online resources for building an ROV such as: SpaceShipOne's example, or this one called HomeBuiltROVs.
2. Frame Assembly
Once you have your supplies it is time to build your ROV frame. This video shows how to cut and assemble your frame.
3. CONTROL BOX SETUP and DRILLING
This video shows how to drill the holes for your control box.
4. Electrical Components
This video goes over the basic soldering techniques and process.
This video shows you how to wire your DPDT switches that control your motors. Use a soldering iron to solder the wires together on your switches. After wiring it together mount your switches into your plastic control box. Use a drill to drill holes in your control box. Then use nut and washer on the switch to mount it into the control box. Use this manual to solder the speaker wire to your control box and tether to your motors.
If you decide to use bilge pump motors the video above is a tutorial about how to use and attach them. Otherwise you will need to waterproof DC hobby motors using this tutorial (Page 8-12). Alternatively, the video below goes through how to wire and waterproof small motors using film capsules.
5. Wiring the fuse
You'll need a fuse to control voltage flow. Below is a video that shows you how to wire a fuse for your ROV.
6. Bon Voyage
Time for your ROV's maiden voyage. Put it in the water and test its buoyancy. You want it to be neutrally buoyant, so your ROV isn't sinking or floating. Have fun!
