Thank you very much for replying !
I noticed I have been following the OpenROV 2.5 V guides ! that's why i got confused !
Actually I have finished assymbling all the parts, programming and collabrating the ESC as well.
I have a questions about the laser. When I press "L" lasers will turn on. So, what I suppose to see and to know ? I mean what is the purpose pf this laser ?
Yesterday I tried my OpenRov in a pool. I had some difficulties to control it ! I mean when I was pressing Backward button it was going straight and down ! and when I was pressing Forward button it was going back ! Also when i was pressing Leftward it was going right and vice versa, How I can fix that ?
Also, sometimes during the test after using it for while, OpenROV was not responding to my commands for a short time ( 30 seconds ) ! and some times it was transmitting my commads with a noticeable delay ! Do you know what might be the reason ?
