Drive Through an Obstacle Course
Problem Statement:
Add blocks to drive the robot through the obstacle course to the star. Make sure you do not cross the tape! You may use drivexy blocks, or use the turn right, turn left, and drive distance blocks.
```/* Code generated by RoboBlockly v2.0 */
#include <linkbot.h>
CLinkbotI robot;
double radius = 1.75;
double trackwidth = 3.69;

robot.drivexyTo(11, 6, radius, trackwidth);
robot.drivexyTo(11, 14, radius, trackwidth);
robot.drivexyTo(19, 14, radius, trackwidth);
robot.drivexyTo(3, 36, radius, trackwidth);
```
```/* Code generated by RoboBlockly v2.0 */
#include <linkbot.h>
double angle1;
double angle2;
double angle3;
CLinkbotI robot;
double radius = 1.75;
double trackwidth = 3.69;

angle1 = rad2deg(atan(0.75));
robot.turnLeft(angle1, radius, trackwidth);
robot.driveDistance(10, radius);
robot.turnLeft(90 - angle1, radius, trackwidth);
robot.driveDistance(8, radius);
angle2 = 90;
robot.turnRight(angle2, radius, trackwidth);
robot.driveDistance(8, radius);
angle3 = 90 + angle1;
robot.turnLeft(angle3, radius, trackwidth);
robot.driveDistance(27, radius);
