Rotate to Angle (FTC)

navX-Micro can be used to rotate a robot quickly and accurately to a specified angle. This can occur not only with holonomic drive systems that provide independent Z-axis rotation (the capability to “spin on a dime” while also moving in a linear direction), but also on robots with only two drive motors  This same technique can be used to help a robot drive in a straight line.

This example code below will automatically rotate the robot to a specified angle. This rotation can occur not only when the robot is still as in this example, but also when the robot is driving. When using field-oriented control on a holonomic drive system, this will cause the robot to drive in a straight line, in whatever direction is selected.

The PID Controller coefficients defined in the example code will need to be tuned for your drive system.
