micro-ROV power

Post by OJR Sea Dogs » Tue Apr 02, 2019 3:51 pm

Hello,

Our team was wondering if stored energy is an allowable power source for the micro-ROV rather than onboard batteries or power through the main ROV.

Specifically, we were considering options similar to those in a pull-back car (e.g. https://www.upsbatterycenter.com/blog/p ... otor-work/ or https://www.youtube.com/watch?v=cb2j40Loaek)

We couldn't find anything in the rules explicitly prohibiting this, but wanted to make sure.

Thank you for your time!

You may use springs, rubber bands, etc. as small mechanical stored energy.

Good luck.

Thank you!

We had one follow-up question, since we are still considering the battery option for the micro ROV as well. Can the waterproofing itself provide pressure relief for the battery?
A mentor recently suggested an open-body micro-ROV that water flows through, with a battery inside. We would waterproof the battery, but wouldn't really need an end cap or valve to open since there is no inside/outside of the actual device. We are anticipating that the waterproofing would rupture safely upon any pressure buildup within the battery. Would this be acceptable?

Thanks again for your time.
