FAQ for Secondary Mission 1

1. Do I need to follow the exact route for A, B & C on the playing field?
Yes. The Participants will have to strictly follow the route on the playing field with or without the sensors existing. The black line of the route on the playing field should be in between the main chassis of the robot.

2. Do I need to follow any of the routes when I'm returning to the base camp?
Yes. The black line of the route on the playing field should still be in between the main chassis of the robot, regardless of any routes that the robot is taking back. .

3. Will there be a container for the robot to unload their ping pong balls when they reached the base camp?
Yes. Containers will be provided..

4. Can my robot roll the ping pong balls back to the base camp?
No. The robot has to securely carry the ping pong balls back to the base camp.

5. When can I touch the robot when it reaches the base camp?
Referee will make sure the controller is fully in the base camp before they are allowed to touch the robot. The robot has to be completely stopped due to its own program..

6. Are we allowed to pour in water to displace the ball out of the box?
No.

7. Will the black plastic Lego blocks be stuck to the board or will they be movable on the actual day?
The black plastic Lego blocks will be stuck to the board..

8. Are students allowed to physically remove the ping pong balls when their bots reach base camp after each sequence (A, B or C)?
The students are ONLY allowed to physically remove the ping pong balls when the referee tells them to do so. The robot needs to completely stop in the base camp before the students can touch the robot. The robot is considered in the base camp once the controller (RCX/NXT) is completely inside the base camp..

9. From the challenge briefing, my impression is that students are allowed to touch their bots after each sequence, as long as the bots stop at the base camp. Does this mean that they can run 3 separate programs, one for each of the sequence?
Once the robot comes to complete stop in the base camp, the student are allowed to change the program for the next sequence..

10. Does returning to the Base Camp from the box of ping-pong balls after reaching it count as running the pathfor the robot? E.g. If the robot runs to the box on path A, collects some balls and returns along path B, does it count as running path B?
No. the robot is considered to have covered ONLY Sequence A.

11. Can the robot run the same path twice? E.g. If the robot returns to the Base Camp along the path B, can it go out again and return along path B? (If yes, can it do so again a few times?)
No.

12. When the robot finishes path C and returns to Base Camp, is the whole challenge considered ended and time stopped? Or can it go out again to collect more balls?
The time will be stopped and the mission ends.
