The Rescue challenge in robotics consists in getting your robot to follow a line until reaching a location where to perform a task. In this case, the example will make it to an obstacle, push it out of the way, and continue its way.

1. Prepare the track, see the list in line following example about how to do it. There're some differences:
1. You need to add some end lines for the robot to stop. Keep 2 gaps on the line, draw a rectangle about the size of the robot in the gap.

• Robot grabbing structure
• "victim" objects

### Instruction

1. Prepare the track, see the list in line following example about how to do it. There're some differences:
1. You need to add some end lines for the robot to stop. Keep 2 gaps on the line, draw a rectangle about the size of the robot in the gap.
2. Put the "victim" objects inside the rectangles.
2. Upload the example, unplug USB and turn on power.
3. Put robot on the track, along the line.
4. The robot will start following the line, and push the victim out of its location
5. If the robot does not follow the line well, see lineFollowConfig() for details about how to calibrate it.
