Homebuilt ROVs Forum

Hi new to forum. been looking thru threads for days but still need some help. building first rov. i am thinking about using gopro for first person view on rov due to the availability of them and info out there. i plan on having wired up to surface but not sure if bus connector , 10 pinn, or hdmi is the way to go. to get video back to either android pad or other small monitor. which gopro model is best for around $200 used. probably 150 feet at most on cord

plan on using arduino with xbox controller to control rov
any and all help appreciated
here are some of the misc parts i have so far
3 rule 25d bilge pumps
1 robot arm claw with pinch and rotate for arduino
1 sainsmart L293d motor drive shield for arduino
1 sainsmart 2 channel relay module for arduino
1 arduino uno mega 2560 r3
1 waterproof temp. sensor ds18b20 for arduino
1 kootec gy521 gyro & accelerometer for arduino
1 sainamart usb host shield for arduino
1 wired xbox controller

thanks alot

Look into SJCAM. They make good Go Pro like cameras which are much cheaper and have live feed over cable. I have an SJ4000. Make sure you get a real SJCAM since there are many knockoffs some of which cannot live feed.

is there a maximum range if you connect via usb out hacked to yellow av cable ?
what about the hdmi could it be used ?
thanks

With SD and cat5 (one twisted pair) you can use video baluns and get several hundred feet of transmission. I'll be doing 100 meters with passive baluns. Not sure about HD options yet.

HDMI is only good for a very short distance (5 m or so). For a HD live feed from the GoPro you would need to convert the HDMI to SDI and transmit over high bandwidth coaxial.
