Use a Robot to Collect Lunar Samples
Problem Statement:
The robot needs to go to the locations marked with red circles to collect lunar samples. Add blocks to move the robot to each of the three points. Afterwards, send the robot to the gold star, where the samples will be dropped off.
```/* Code generated by RoboBlockly v2.0 */
#include <linkbot.h>
CLinkbotI robot;
double radius = 1.75;
double trackwidth = 3.69;

robot.setSpeed(20, radius);
robot.drivexyTo(3, 6, radius, trackwidth);
robot.drivexyTo(14, 6, radius, trackwidth);
robot.drivexyTo(28, 9, radius, trackwidth);
robot.drivexyTo(21, 14, radius, trackwidth);
