    Creating Function Library

    Make a list of behaviors that your robot does consistently (e.g. make a 90 degree right or left turn)



    Begin turning some of those behaviors into functions and save them in your function library.

    Mini Challenge 1: Lined Maze

    This challenge requires the robot to be programmed to navigate a maze.

    Each section of the maze requires an extra line to count.

    Students should use the one line function to help solve this challenge.
