Trace On/Off: Drawing the Path of a Robot in the Coordinate Plane

 

Notice that while driving, the robot draw a line(s) on the grid. This is called the trace line. You can choose to turn on or off this feature using the block: 

The "On" setting will draw trace lines showing the path that it drives through. When turn to "Off", the robot will drive without drawing any trace line. 

You can turn the trace line On/Off many times during a program, which is useful when using the robot to create drawings on the grid. 

Watch the video for more information about the traceOn/Off block.

Tracing the Path of the Robot in the Coordinate Plane
Problem Statement:

Use the trace block to trace the movement of the robot from (0, 0) to (6, 5). Then have the robot move from (0, 10) to (6, 15), again tracing the movement of the robot. You do not want to trace the position of the robot between moves.

/* Code generated by RoboBlockly v2.0 */
#include <linkbot.h>
CLinkbotI robot;
double radius = 1.75;
double trackwidth = 3.69;

robot.traceOn();
robot.drivexyTo(6, 5, radius, trackwidth);
robot.traceOff();
robot.drivexyTo(0, 10, radius, trackwidth);
robot.traceOn();
robot.drivexyTo(6, 15, radius, trackwidth);
