The Challenge

 

The Morris County Robotics Challenge requires that a participating school design and build a single robot from the parts found in only one Lego or Pitsco Mindstorm kit. The only exception to this will be the software. Teams will have the option (and also take on the responsibility and risk) to use any software package to program the RCX unit. The robot will compete in two different events.

 

The only additional pieces required by each student team beyond what is found in the kit will be, 1) A few rubber bands, 2) weights (5, 10, 20 pounds), and 3) The 3” school sign/attachment for the robot.

 

The events are, 1) Pulling and 2) Follow the Curve. Each event will consist of three heats.

 

During a heat on either event, if the robot goes off course during the first 6 inches the team will not be disqualified and will be given another chance to make the run.

 

Teams are limited to 3-6 students. There will be a maximum of 30 teams competing during the day of the event. Special exemptions to this rule might be made including non-competitive demonstration events.

 

The score of each team for each event will be totaled to determine the winner. In the event of a tie, the tied teams will rerun both events and the team with the best total score for all heats including the run-off will be declared the winner.

 

Pulling

 

The pulling competition is designed to test the pulling strength of each robot. Each team will have three opportunities to have its robot pull a weight down a 36-inch long course.

 

A program and light sensor must be used by the robot for this event. Just turning on the robot and letting it travel straight ahead is not permitted. The program must help the robot negotiate the white area between the end of the straight black line it must initially follow and the end of the course. The robot must follow an imaginary continuation of the straight, black line to reach to end of the course.

 

The student teams must build both the robot and the trailer to hold their weights (potentially up to 20+ pounds). The weight of the trailer is not considered part of the total weight. Students should optimize the design of their weight trailer so that it is strong and light weight, yet easy to roll.

 

Students must also design a hitch/drawbar that can securely pull the trailer and stay on the full length of the course for multiple heats.


Rubber bands (in reasonable number) can be used to keep the weight secure on the trailer and the robot together. Rubber bands CAN NOT be used to keep the hitch/drawbar together or connect the robot to the trailer. Glue CAN NOT be used.

 

The robot, trailer and the hitch/drawbar that connects them, MUST BE built from the parts in ONE Lego or Pitsco Mindstorm kit.

 

Points are calculated as follows: Take the total distance traveled in inches.  The measurement is made from the 0” point to the centerline of the trailer wheels/tires.  If the robot travels off the line and the centerline of the robot reaches either of the dashed lines (after the first 6 inches), the team will receive points for that heat based on the distance traveled and time before crossing the dashed line.

 

A “full pull” is made when the robot and its weight trailer travels the full 36 inch course while the centerline of the robot stays between the dashed lines. Special Note: The robot will be traveling for a short period of time without a guideline!

 

If the robot makes a “full pull” during the first or second round, 5 more pounds will be added.  If the robot can once again make a “full pull” the team will be awarded points for a second heat.

 

If this occurs during the second heat, 10 more pounds will be added and the team will be awarded points for the third heat.

 

The maximum time allotted to each team, for each heat, shall be 5 minutes from the time the robot is placed on the pulling course. Teams unable to pull the weight any distance within the allotted 5 minutes will not receive any points for that heat.

 

Team members are not allowed to assist the robot during this event. Any team that assists their robot will not receive any points for that heat.

 

Follow the Curve

 

The follow-the-curve competition is designed to test the robot’s ability follow a curve and stay between the two inner/outer dashed lines around the course. If the centerline of the robot passes through either dashed line, its’ team will only be awarded points for the distance and time traveled up to the intersection of the dashed line.

 

Points will be earned based upon the total distance traveled within 5 minutes. A robot that can travel the full 96-inch long course within this time will earn 96 points. Each team will have three opportunities to earn points.

 

Each heat will last 5 minutes. During the event team members are not allowed to touch the robot. The centerline of the robot must stay on the solid curve line between the two dashed lines during the heat.

 

Teams will have three opportunities to travel the course and the best time and distance all three heats will be used to calculate the teams point score.

 

Tie-Breaking

 

If a tie exists for first, second or third place for the overall Competition Championship the teams involved in the tie will rerun the two courses.

 

Each team involved in the tie will have one opportunity to run each course and the team with the best total score will be declared the winner of the tie.


The Course

 

The Pulling and Follow the Line courses can be found on one “E Size” 36”x48” drawing as shown in reduced copy below. Copies will be made available to participating schools and are also available online at http://www.fes-nj.com/Lego/

Rules

 

1.     All participants must behave in a sportsman-like manner.

2.     The order of play will be randomly determined prior to the start of each event.

3.     Robots built with unauthorized materials will be disqualified until the unauthorized materials are removed.

4.     Robots CAN NOT be built using glue. Rubber bands can be used (within reason) to keep the robot together.

5.     Robots that are made from parts other than those contained in one Mindstorms will be disqualified until they meet this requirement. The only exception shall be the programming software as previously noted.

6.     Prior to the start of a team’s first heat a disqualified robot may be modified to qualify and meet specifications.

7.     Robots may not be modified after inspection and weigh in.

8.     Broken parts may be repaired with new identical replacement parts.

9.     Teams will be given 5 minutes to set up for an event. If a team is not ready to compete within the 5-minute time period they will not receive any points for that heat.

10.  A team’s highest score for each event will be added together to determine the Competition Champion.

11.  Any controversies derived from the rules or actual competition will be resolved by the Competition Judge. The Judge’s decision is final.

12.  Robot malfunctions or operator error will not be grounds for additional heats.

13.  A robot will be disqualified from a heat if it contaminates the playing field.

14.  The use of cellular phones and two-way radios will be prohibited during the competition. Violators will be asked to leave the gym.

15.  A robot that is designed to intentionally cause damage to any part of any playing surface will be disqualified from the competition.

 

Safety

 

1.     During construction, testing and competition please emphasize that safety comes first.

 

2.     Check all electrical wiring prior to connecting the motors and testing the robot.

 

3.     Test controls in an open area or with the robot propped up such that the wheels or drive mechanisms are not in contact with any surfaces.

 

4.     Do not chase team members with the robot.

 

5.     Robots that do not appear to be stable or suitably constructed will not be allowed to compete.


 

Scoring

 

Teams will have three opportunities/heats, to get the best score possible for any given event.

 

All teams will have competed in the first heat of a given event prior to any team starting their second heat. All teams will have competed in the second heat of a given event prior to any team starting their third heat.

Special Advisories

1.     Teams are advised that light levels in the competition area may be different from those encountered during their testing and development work at their school. Teams should test their “line following” capabilities before the start of the event to prevent any unexpected results and make any last minute changes.

 

2.     Teams are advised to place a fresh “fully charged” set of batteries in their robot for the day of the event. Having a backup set available is also advisable.

 

3.     Teams should bring or make arrangements for laptop computers with the Lego Mindstorm software (or alternate software package), and IR unit/cable and copies of their programs for each event (with backups) to make any last minute changes or fine-tuning before the event. Teams are advised to test this equipment for proper operation with their programs and robot before the event.

                       


Robotic Kits, Parts & Supplies

 

1.     The robot must be built using only the parts provided in one Lego or Pistco Mindstorm kit (except software).

 

2.     Read the entire manual and check all parts prior to starting the robot design.

 

3.     Each robot must display their team’s school name in 3-inch high letters on a clearly visible part of the robot. Also clearly indicate the centerline of your robot.

 

4.     No tape may be used for robot construction.

 

5.     The weight pulling connection must be located in the center of the robot on the rear edge. Mount the connection securely. A pulling connection failure is considered a mechanical failure and is not grounds for additional heats.
