#define MAX_SPEED 127
// Set motor maximum speed, this allows for tweaking the speed of the robot with one change.
#define MAX_AUTO_SPEED 100
/* During the development of the autonomous portion of our code, we found that the robot
would have issues turning and driving at MAX_SPEED causing it to turn too much, and
not driving straight. After limiting the driving speed to 100, we found that the robot
was able to drive more consistently.
*/
#define STOP 0
// Defines the value for when a motor is stopped.
#define DEADZONE 10
/* Defines the deadzone of the VEX controller. With our controllers, a value of 10 allowed
for the motors to completely lose power when the joystick is let go.
*/
#define DRIVE_OFFSET 10
/* Defines the offset used to correct curves while the robot is driving straight during the
driveTiles(float numberOfTiles, bool direction) function.
*/
#define TILE 1206
/* Definition for Rotation points per tile.
Each tile is 23.4 inches wide.
The exact radius of 4" omni wheels, using dial calipers: 2.075 inches
2 * pi * r is circumference of the wheel - 13.0376 inches
There are 627.2 points in a revolution with the vex direct motor encoders - according to robotc
developers: “The 2-wire 393 motor measures 627.2 counts per revolution of the output shaft in its
default high-torque configuration and 392 counts per revolution of the output shaft in its
modified high-speed configuration.”
So if we do 1 revolution * distance / radius we get 627.2 * 23.4 / 13.0376 = 1206.
When the integrated motor encoder reports a movement of 1206, that means the robot has moved 1 tile.
*/
// How much the wheels should spin in a 90 degree turn
#define POINTS_PER_TURN 320
/* Using trial and error, we found that our robot will make a 90 degree turn when the integrated motor
encoders report a distance of 320 while spinning in place.
*/
// definitions for driveTiles()
#define FORWARD true
#define REVERSE false
/* When the function driveTiles(float numberOfTiles, bool direction) is called, one of the explicit
parameters is a boolean for direction, where true is forward, and false is reverse. Using these
definitions in our code, it is clearer to us and readers as to what that parameter is for.
