R/C car pistol grip style controller

I agree that overcomplicating things would be a bad idea. Even better would be to make a glove full of pots so you can control your robot by moving your hand around! That's what I'd call magic!

It's been done... a few times. I'd assert it's not the most intuitive control system. Something about how mapping X input into Y output isn't obvious to a casual observer.

From my experience as a driver for 2 years on 842, the pistol grip controller was extremely intuitive. I had been practicing for a month with joysticks but was nowhere near as good as I was with the pistol grip. With gyro assisted drive and even just a moderate amount of practice, the pistol grip can turn anyone into a top tier driver. Last year we decided we didn't want the cypress board anymore so we took apart the guts of a regular gamepad controller and mapped the potentiometers from the pistol grip controller to to the joystick inputs. After doing this, the computer will just see the pistol grip as a regular gamepad.

Holomonic is how the programming control type works, behind drive train where you have the capability to divorce the drive bases orientation away from its main drive direction creating a 2D drive.(Where a drive can drive a straight line and still rotate)http://www.youtube.com/watch?v=p9WHMssEF4U what a good representation of a holomoic drive mode looks like. teams 1640 ocolate drive is anouther.

A crab drive is not a holomonic drive because it can not do the 2D drive motion.

If I'm not wrong, that looks like a swerve drive (and I know 1717 uses lots of swerve in their robots). Holonomic would be Mecanum/Omni!

What if you take apart a regular joystick, and build another enclosure for the pots? You can re-engineer the joystick to look and feel like piston-grip!

Think like an engineer! Think about how you can modify what you HAVE to get what you WANT!

its easier for me as a driver because i have been racing my r/c cars at a track and its easier to use a cheesy drive program on a pistol grip rc controller because its just what im used to
