DIY submersible ROV flies through the water

If you’d like to check out your pool or a lake without getting wet, this underwater ROV looks like a great solution. 

The DIY device features a sturdy PVC frame with six thrusters that allow it to move through water like a drone through the air (complete with depth and heading hold), and uses the same kind of controller configuration as its airborne cousin.

Onboard control is handled by an Arduino Mega along with an FPV camera, which transmit signals back to a base station via an Ethernet cable stuffed inside of a length of polypropylene rope. The driver can then see what the ROV sees on a small display, supplemented with data from the base station’s Arduino Uno and an onscreen display (OSD) shield.
