Depending on your swimming and breath-holding ability, you can dive into a body of water and look around for a while, but after a few seconds, or perhaps even minutes if you’re extremely fit, you have to come up for air. If you’d like to look around for an extended period of time without getting wet or tiring yourself out, this DIY submersible ROV looks like just the thing.

The craft, constructed with a solid frame of PVC pipe, features six thrusters that allow it to move around in three dimensions in a similar manner to a quadcopter. It also uses the same sort of control configuration, along with a FPV camera signal so the driver can observe its surroundings. As radio signals don’t work well underwater, data is transmitted via an Ethernet cable embedded inside a length of polypropylene rope for protection.

An Arduino Mega is placed inside of a dry tube for control of the vehicle, and signals are transmitted to an Arduino Uno operating at its base station, where on-screen data is added via a shield interface. The device also features heading and depth-hold, helping the user concentrate on simply making the ROV travel where it is needed. Be sure to check it out roving around a pool in the first video, and what the device’s FPV display shows while traversing a hot tub in the second.
