Re: Turning Quality Metrics

An easy characteristic to measure that could be considered a turning metric is the "drive symmetry" of the drivetrain. It comes down to the relationship between turning to the right and turning to the left.

Under most circumstances, you want a set differential force to turn the robot at a certain rate, regardless of the direction of the turn. An easy way to test this on a robot is to spin in place at full power, first clockwise, then counter clockwise.

The reason why this is important is that a more "symmetrical drive" will require less trimming to drive straight, giving the driver more power to play around with.
