May I know what is role of each : Arduino, Beagle and Tether.
I have noticed the Motors, sensors, etc controlled by arduino ! what about beagle ? what's role of it in Open ROV !
Also Tether, I have been told that the only use of tethers is sending data ! but I have noticed that if I do not connect the USB to my PC/Laptop the Board will not be turned on !
I would really appreciate if you explain these to me.
