Testing underwater interplanetary robots on the cheap

This article describing a test of an underwater robot by JPL scientists in the interior of a glacier warmed the cockles of my heart when I read this paragraph:

Klesh and Leicty’s recent expedition relied on a commercial grade submersible and a “homemade” glacial probe. The latter was built using off-the-shelf and 3-D printed parts. They did all their own wiring and programming.

NASA test projects like this are often gold-plated. I like how these scientists took a more practical approach, getting their data without spending a fortune in time and money. Moreover, they gained some engineering knowledge that can be applied practically in future probes, both here on Earth and on other planets.

    Mr. Z: Many years ago when I managed a RadioShack store there were rumors that various Nasa engineers would stop by their local RS to get various parts; resistors, capacitors etc. Waiting to go thru channels took a lot of time and the final cost was huge.

    As I understand it these parts were used for experimentation, mock-ups etc. They never flew (as far as I know) and the folks at JPL seem to carrying on that tradition.
