Double Dutch at Recess

Do you ever get tired of holding the end of the rope and turning? Now you can create two robots that do it for you. Sit back and wait your turn to jump, but never worry about turning again.

In this event, teams will design and program two robots. Both of the robots must be able to attach to one string. You may use your own type of string. Teams must program the robots so that the string can turn in circles as if it were a double dutch rope. The string cannot touch the ground, and the two robots must be synchronized so that the string turns at a steady speed. Robots can be a maximum of 3 feet apart. If the double dutch rope goes through three steady rotations, you have completed the challenge.

Judging Procedure:
1. One team will compete at a time.
2. A string will be tied to two robots.
3. Students should press the red "On" button on their vehicle and set their vehicle to the proper program.
4. On judge's mark, students will push the green "Run" button.
5. The robots must rotate the string 3 times in unison.
6. If the string touches the ground, the trial does not count as valid.
7. If the two robots are not in unison, the trial does not count as valid.
8. Teams get three trials to try and make the double dutch rotate properly.
9. When finished with all three trials, complete the rubric and determine the top three finishers. Complete the results sheet and turn it in to the scorer's table.
*note: Vehicle needs to be programmed to stop. If it stops after 3 rotations, the team will be awarded 5 points.
