List of Parts and Supplies

The C-DEBI Catalina ROV is based on parts and materials that were available in local hardware stores or could be purchased over the Internet during the 2011-2012 academic year. Availability will undoubtably change over time and from location to location. Nonetheless, these plans should remain useful as a starting point and guideline, even if you need to make a few creative substitutions for parts or materials not available to you.

The specific parts, materials, and tools needed to build each part of the ROV are listed under the instructions for building each subsystem, but here’s a quick overview with approximate prices at the time we originally made the ROV.
