Drivetrain PID tuning - Chief Delphi

When there appears to be something stupid wrong with a game (HPs outscoring robots, unreliable loading, autonomous that accomplishes nothing) I shouldn't complain about it. I should see it as a challenge to exploit! - Chris is me [more]

short answer: wheels slip.

Once the wheels have slipped against the carpet/floor/obstacle and you don't know how much, you can't reliably use the encoders (by themselves) to determine orientation. Gyros have more drift, but are not subject to this sudden loss of calibration.
