So yes, lots of pressure on a little surface.
It was evident that lubricant was necessary, but as the material was latex, we had to opt for water-based lubricant since oil-based lubricants degrade latex. Well, the only water-based lubricants available near the regional were in the form of personal lubricants at the nearby drug stores and supermarkets.
In our pit for the rest of the event, we had a tube of Astroglide covered with red duct taped and labeled "Secret Sauce." We applied a fresh coat to the latex tubing before every match.
Not sure if it's the kind of "ghetto" you're looking for, but it's certainly an unexpected fix to a problem. Worked like a charm, though.

We applied white lithium grease to the surgical tubing bundle of our 2014 bot. It kept disappearing so we kept adding more, worked fine all season.
Edit: also at our first event we had to C-clamp a major component(without it we couldn't shoot properly) into place after it broke, we then proceeded to run 2 perfect cycles back to back at Inland Empire with a seriously crippled robot.
