Tracing Challenge

This challenge is like tracing / going through a tiny path which is not always straight !

4 levels to go through this maze wall : robot's arm has trace one or all (by carrying a pointer or its own finger) to win 1-4 levels

level 1 is just an horizontal move (looks simple but narrow path) (5 points)

level 2 is an horizontal and vertical move (a little more difficult) (10 points)

level 3 is a zigzag path so robot should be able to move the arm in such a way (20 points)

level 4 is a round and sharp way not easy to follow (maybe 50 points)

Basically; each level is a not very long road to drive but it can be difficult if the robot's arm is complicated to control.

Flags get up whenever a level is passed - Cool
