The Groove Machine Challenge

In this challenge, you will break up into teams and program your robot to go through a dance routine using your knowledge of loops. Your teacher will set a time limit for developing/testing the dance and a time limit for the length of the dance. Everyone not on the competing head-to-head dance-off teams will judge the dances and vote on the team that they think is best.

Rules:

  • Each Clawbot will dance one-at-a-time within the 1x1 meter area.
  • The dancing continues until the Stop button on the Brain's screen is pressed to stop the project from running.
  • The arm must be raised and lowered.
  • The claw must open and close.
  • The Clawbot must turn left and right.
  • The Clawbot must drive forward and in reverse.
  • The project needs to be stopped immediately if the Clawbot collides with anything or falls over. That is a losing dance.

Bonus Challenge: Add sounds from the brain and colored lights from the Touch LED to make your dance routine better than the others.

Judging for this competition could be handled in a number of ways. One way to increase engagement is to have students video record the dance-off and have students from other classes vote on the winner. If that is too ambitious, consider appointing a panel of impartial judges before beginning this challenge, or bringing in other students, teachers, or staff.
