The robot was on blocks, not moving (visibly), all 5 modules were plugged in, and the wire went from the crio away from the cims, turning at about .2-.4

Yes, team 1388, Eagle Robotics used a gyro for their steering mechanism. I was so impressed as to how it worked. They had a bike tire, with pegs on each side to show the concept.

This is an active gyroscope with a rotating mass. The original poster was referring to a MEMS sensing gyroscope.

But yes, Eagles Robotics' gyro system was very cool.

Figured out our problem, we thought the gyro was using 0-1, so we were multiplying the results by 360. actual drift was only 0.01 degrees a second.
We also had driver testing, and decided to not use this drive system. They liked Twist joystick Arcade better

In "real life" I do a lot of work in human-hardware interaction and measuring effectiveness of different ways of doing things. Without reading too much into it with respect to the particular merits of one control paradigm over another, consider some general thoughts:

What seems (or what they say is) easier or more intuitive to people isn't necessarily. When you want to evaluate the effectiveness of alternatives, measure their actual performance on tasks similar to the ones you care about. "Intuitive" often is used simply as a synonym for "familiar", and people with hard-won skills in a difficult task are prone to describing what they do as "easy".

Subjective evaluations like these are notoriously untrustworthy. If you want to find out what works best, measure how well things work. If you want to give people what they like, ask them what they like. Be careful about confusing the two.

And then give them feedback in the form of a side-by-side test, as blind as can be -- placebo effect doesn't only affect drug tests. Sometimes it takes a skill test and measured data to convince someone of their own performance numbers.
