Bilge Pump Shell for a Mini ROV-- Updated
Description
These parts come together to create a mini-ROV powered by a bilge pump motor, designed to navigate a tight, dark pipe. It was originally designed for the 2020 MATE International ROV Competition, in which the mini-ROV was deployed from a larger ROV to collect a sample from the end of a pipe. (We're a high school robotics team, Seal Team Scalyr, and were planning to compete at the college level with this robot.) It's an updated version of an earlier model from last year's competition, which can be found here: https://www.thingiverse.com/thing:3731751 The biggest update for this design was the incorporation of a contra-rotating gear assembly, adapted from RossWorks's file. Last year, the mini-ROV rotated as it navigated the pipe. With the contra-rotating propellors, each propellor spun in the opposite direction, cancelling out any rotational movement. A bilge pump motor fits inside, with an AquaVu fishing camera in front, positioned at the top looking down. Best of luck if you use this design! It was fun to make and worked well in the water.
