Shocker MINDSTORMS Challenge

Answers to Frequently Asked Questions (FAQ)

Please check this site frequently. Any notifications and/or clarifications for the Missions will be posted here as soon as they become available.

If you have a question about a mission or the Challenge in general, please fill out the Questions form. This will help us answer questions more efficiently and archive questions and comments for use in future planning. Please do not send questions through e-mail. Thank you!

When asking questions, please keep in mind that the FAQ page is meant to address questions about basic design or fundamental rules and goals of the Missions. The Missions are designed to encourage teams to think about alternative ways to design and program their robots to complete specified tasks. Exact reproduction of the courses is not necessary for programming and development. On Trial Day, each team will have the opportunity to ask detailed questions about the Missions. Teams will also have time to test their robots on each course and make modifications to their designs and programs as needed. MINDSTORMS robots are meant to be autonomous - they should react to their environment. For example, if the tape is not in the exact position as noted, the robot should not be affected. Also, note that there is a 1/8" tolerance on the building of all competition courses.

Team Display	Do team members need to stand beside the Team Display?	No. The Team Display does not need to be manned.
Team Display	How many team members may be used to setup the display.	There is no required number of student participants involved in setting up the display. (No adults allowed!)
Team Display	Can a display hang over or extend beyond the table?	No. The display cannot be larger than the table top. Exception: a cloth or table cover can be used. It can hang below the table top, but should not take up any additional space and will not be part of the information judged.
Team Display	What are the dimensions of the table for the Team Displays?	The tables are 6' x 2.5'.
Team Display	When judging the display will the judges look in the notebook or will they only judge what is displayed on the table in plain sight?	The Team Display and the Team Notebook are two different competitions. They are judged independently of each other using the scoring sheets for the Team Display and Team Notebook
Apprentice Courses	Is there a time limit for the Apprentice courses?	Maximum time limit for official runs on Apprentice Courses is 3 minutes. The run will end at 3 minutes and teams will receive the scores earned up to that time. few courses have their own time limits to earn more points, visit those courses to see the time limits.
Line Follower	Is the robot only allowed to use one light sensor?	No, multiple light sensors are allowed.
Line Follower	Does robot have to stop at end of run?	No.
Line Follower	What is the start position?	The rules state: Your robot must begin its run while the back of your unit is lined up with "A" .
Line Follower	Can you use a color sensor?	Yes, you can use either a light sensor or a color sensor.
Line Follower	What constitutes the ‘back' of the robot?	The last physical piece of the robot including wheels, wires, and sensors.
Line Follower	What constitutes ‘1-inch' off the track?	The entire robot has to be more than 1” off the black track. As long as the robot is touching or at least within 1” of the track, they are okay.
Line Follower	Does the robot need to be programmed to report the time it took to run the course?	No. The judges will use a stop watch to determine the time in which the robot finishes the course.
Table Runner	Do you have to use touch sensors for this challenge? There is another way.	From the rules, "The purpose of this Apprentice Mission is to utilize the touch or force sensor capability of the robot. You must therefore show satisfactory evidence to the course Judge that the unit is utilizing a touch sensor to direct its motion and change of direction when reaching the edge of the table."
Table Runner	Are ultrasonic sensors allowed?	No.
Table Runner	Is there a specific starting orientation required?	No.
Table Runner	Does the robot have to stop when completed?	No.
Table Runner	Are there any restrictions on size of the robot?	Yes, robot including wires must not be larger than 10 inches in any direction.
Table Runner	Does the robot have to touch the “X” on each pass?	No.
Table Runner	Does it count if the robot rolls off the edge on the eighth touch?	No. The course rules state “Touching the edge will be determined if the activation of the touch sensor at the edge of the table causes the direction of motion to be changed without the unit falling off the table.”
Table Runner	Can the table be cleaned?	No. We will try to provide the best table available. All participants will be competing on the same table throughout the day.
Table Runner	Can another sensor be used to assist with alignment as long as it is not the trigger for the change of direction activation counting as a side touch?	Yes. The Mission Judge will need to be provided satisfactory evidence that the unit is utilizing a touch sensor to direct its motion and change of direction when reaching the edge of the table.
Maze Runner	Do robots need to use a specific sensor on Maze Runner?	No. Any sensor can be used.
Maze Runner	Can multiple sensors be used on the same robot?	There is no limit on the type or number of sensors used for the Maze Runner.
Maze Runner	Are we encouraged to design a program optimized for the particular maze, e.g., by instructing the robot to go forward by 2 feet, then turn left, then go forward by 1 foot, etc.; or design a sensor-based universal program that would work for other mazes, sacrificing the efficiency for the specific one?	There are no limits to how you use sensors or program your robot for the Maze Runner. The goal of the course is for students to build and program a robot that autonomously responds to its environment.
Maze Runner	Can the robot's height break the plane of the top of the Maze Runner walls?	There are no restrictions on robot size or construction.
Maze Runner	If there is a tie for 1st and 2nd place, will a winner be determined by how quickly they finished the course, or will it remain a tie?	The scores earned for each course are only a small part of determining an overall winner at each level (Beginner and Beginner II). Time is not a tie-breaker consideration.
Maze Runner	Do the Checkpoints need to be passed in sequential order to earn points?	Checkpoints can be passed in any order or sequence. They may be skipped if teams choose to do so. In order to achieve points for any checkpoint, all wheels, tracks, or parts of the robot in contact with the base must completely pass the checkpoint.The run is declared to be over if the robot becomes stuck and unable to move for 5 seconds.
Maze Runner	Does the back of the robot have to be touching at the start or can a cord be touching?	Anything attached to the robot (must be LEGO component) is considered a part of the robot.
MOMS	Does the robot have to physically touch the yellow areas or can a component of the robot simply pass over it?	The robot must physically touch the yellow areas.
MOMS	Are points deducted for touching the back side of the walls?	No.
Towers of Doom	Is there a scoring penalty for touching or knocking over the towers?	There is no scoring penalty for touching the towers, and the construction of the course makes it unlikely that the towers would be knocked over by a robot.
Towers of Doom	Would attaching the towers to the course with Velcro have a negative effect?	One negative effect of velcro is that the towers will move when bumped by the robot. The towers on the official course will not move. If your robot never touches the towers, there should be no negative effect. With that said, you are free to attach the towers however you prefer.
Towers of Doom	Does the entire robot need to be inside the red starting square?	Only the elements touching the surface must be inside the red area.
Towers of Doom	Does this course require use of a specific sensor?	No.
Towers of Doom	When are points earned?	Points are earned the first time (only) that any part of robot passes over a corner.
Olympic Rescue	Can you clarify the route of the olympic rescue? What do the students do with the circle on the side of the course? Do they have to pick something up or just drive over it?	Neither the scoring matrix nor the checkpoint map include any reference or action with respect to the course route or the circle.
