We set a maximum acceleration and maximum velocity in order to get the most accurate results. We also tune 2 constants that scale the profile's output velocity and acceleration to actual motor power.

The robot currently has a very slight drift (2 inches over the course of 10 feet), mostly due to chain tensioning. This drift can be corrected in the code with gyro feedback control, which we do in the season.
