Hi guys, got a few more questions regarding the Submersible ROV I am currently planning on building.
Basically, I'm just wondering if this is the correct setup for what I am planning. I want the control unit to have video feed displayed on a LCD and a Xbox 360 USB controller plus switches to turn LED lights on/off.
My idea is to have an arduino on board of the sub controlling the thrusters and lights. An arduino in the control unit on land would receive input from the xbox pad and switches then send commands to the one onboard. I am using a raspberry pi to display the video feed on the display, and I am also toying with the idea of a python GUI to display the video feed and maybe interact with the sub. I know that i will need to communicate over rs232/422 to reach the tether length I want, with that in mind would the raspberry pi be able to replace the arduino in the control unit and communicate and control the arduino on board?? Would there be any speed decrease?? Or should I stick to an arduino in the control unit with the raspberry interacting with that one
Another idea i was thinking about was some sort of hud on screen, and one of the bits of information I would like on screen was depth the sub was at. I cant seem to find a sensor module for this and I dont know if one exists, but if not would it be feasible to use a water pressure sensor from say a central heating unit with the arduino and work out the depth from the reading from that?? Something like This
Thanks in advance
