I've worked with large construction class ROVs for about 6 years, but have always been intrigued by the flexibility of small inspection and hobby size subs. My project idea is to lightly modify a small kit ROV to be mounted in and flown from a bigger ROV. This isn't a new idea, but the goal would be to use this platform of power supplier/host ROV to experiment and modify and test out new idea for home built subs in a way that launching them from the surface just wont provide. It would give way to makers and bold experimenters to test their modifications from deeper depths, in clearer water, with unlimited power supply. The exclusion of batteries then opens up further into playing with different voltages, adding heavier accessories, and even changing thruster configurations or sizes. Things like oil filled electronics housings or electronic manipulators can be experimented with, and from a platform that gives a complete 3rd person overview of the sub being modified and tested.
From a working standpoint a smaller "accessory" sub would prove invaluable for exploring tight spaces, inspecting leaks or issues with the larger ROV in areas it can't see with its own cameras, and being able to return the favor to its host and provide broad overview to a work or exploration site.
