Homebuilt ROVs Forum

Hi.

I'd like to introduce my ROV project design.

Underwater.
Controlling system - Arduino nano 3.
Engines - brushless motors, controlled by ESCs.
Power - one or more LiPo.
Light - most probably diode lamps.
Camera - a simple CCD camera module with RCA connector + RCA-cat5 adapter.
Connection - rs485 chip connected to Arduino and one of the tether's twisted pairs.
Sensors - compass is really needed, but as far as I have some 10dof IMUs, I will use them via SPI, so Ryboscope will have gyro, accelerometer and compass. Depth sensor is needed as well, but I,m not sure now which one to use.
Frame - polypropylene tubes with various fittings. Most probably flat plexiglass will be used instead of a dome as I do not have one.

Tether.
Cat5 cable.
2 twisted pairs - for rs485 connection.
1 twisted pair - for video transmission.
1 twisted pair - reserved.

Shore.
Arduino nano connected to laptop.
Rs485 chip connected to tether and Arduino.
Cat5-RCA adapter + video to USB converted connected to laptop.
Laptop with controlling GUI program (I suppose QT5 will be used to get cross-platform solution).

The design is rather usual, however, please comment my ideas and criticize if needed

The max depth in my country (Belarus) is about 50 meters, but the most usual is about 5-10, so high pressure is not expected.

Sounds like fun.
I look forward to seeing pictures.
Keep us updated.
