This lesson introduces students to the concept of Advanced My Blocks - the NXT-G equivalent of passing a parameter to a sub-routine. Have students watch the [1]"Advanced My Blocks" [2] [2]video from Dale Yocum's NXT Tutorial series.

• Have students resurrect their program for [3]Obstacle Detection Challenge [4]("Obstacle Detection" Lesson)

   

  • This time, have the robot slow down as they approach the obstacle, rather than coming to an abrupt stop
  • Have students use Advanced My Blocks and strive for a program with the fewest blocks possible

     

    • Identify repetitive sections of the program and implement Advanced My Blocks to simplify
    • The most elegant solution will involve nested My Blocks - a My Block placed inside a another My Block
  • The US sensor will be used to adjust the approach speed in an obstacle detection Advanced My Block
