Pure Pursuit: Tank

Same thing as the mecanum version of this module. Just make sure to replace the moveToPosition function with the one seen in tank drive part 2:

double xError = targetX - robotX;
double yError = targetY - robotY; 
double theta = Math.atan2(yError,xError);
    
// 0 is the reference because we want the distance to go to 0 
double distance = Math.hypot(xError, yError);
    
f = distanceController.calculate(0, distance); 
t = angleController.calculate(theta, robotTheta);
// Range.clip is included in the SDK and will clip between two values
// angleController.error is a demonstrative attribute that gets the error. 
f *= Math.cos(Range.clip(angleController.error, -PI/2, PI/2));
    
// set motor power here! 
setRobotRelative(f,t);
