Untethered ROV

I spent over 1200 hours in the design, development, and build of this "Untethered ROV".  Now you can reap the benefits!  Please watch the video.  I will add more info here in the coming days.  This is a very well-rounded project for people who like projects and learning.  My approach is to give you enough information to get it done, but encourage you learn and figure things out on your own...with me as support of course.

You will need access to software that allows you to open a step file of an assembly, take measurements if needed and open files within the assembly.
