This is one of my personal ‘Holy Grails’ – an underwater Remotely Operated Vehicle containing a Pi. Although it’s not controlled by the Pi, I think this one counts!
Tim Jagenberg and his son are currently attending the Maker Faire in Trondheim at the moment and they have taken their ROV with them. Here’s what Tim had to say about it:
[It is] based on a plumbing tube used for the housing and submersible electric pumps as motors. A Raspberry Pi with Camera Module will deliver the live video feed via ethernet cable. The remote control is managed via a serial link to a Teensy 3.1 with sensors and motor controllers. The communication will be implemented using MAVLink, which enables the use of the QGroundControl station.
