Weird PID values.

[techcatgato]

Hi all! I am competing for FLL and started optimizing my movement for speed and accuracy. I am assuming that the pid values that are used by .straight() for staying straight are heading_control.pid(). These seem weird to me coming from normal programming, they seem way too large and out of proportion. printing them results in

(21242, 0, 5310, 6, 11)

What is large? Traditionally, people forget to associate units with kp/ki/kd, so large or small doesn't mean anything.

We like to be specific about it, though, so we do have units for them. Have you consulted the documentation for the units of the values? 🙂

I'm comparing the kp, ki, and kd here to what they should be in for example a line follower pid using stock firmware. I do not know the units

That's why proper units are invaluable :)

If the LEGO stock firmware uses arbitrarily guessed values, I wouldn't know how to use or convert them.
