The Robot Design

Robots may be any brand, designed and built by an individual or teams. Each age bracket will have a game that requires remote control and a game that requires autonomous coding. Bots may enter both contests if able to function in both modes. Teams/individuals with single function mode robots may enter two separate robots (one in each contest.)

BOTS for 5th Grade and Under:

Construction, Weight and Size:

For PING PONG MANIA - Remote Control

For all bots participating in the REMOTE CONTROL PING PONG MANIA, the maximum weight allowed is 2lbs. In addition, there are maximum size specifications:
  • Maximum Width: 10 inches
  • Maximum Length: 12 inches
  • Maximum Height: 18 inches
For ROLL THE DICE - Autonomous Control

For all participating bots in the AUTONOMOUS ROLL THE DICE, there is no weight restriction since bots will compete one at a time and not be in contact with other competitors. The bots must be fully autonomous and self-contained. No transmitters or communication beacons (other than GPS) of any kind are allowed. You may NOT tether to a laptop or other device. Everything necessary for the vehicle's navigation/processing/sensing must be attached and part of the vehicle itself.

Size limitations are:
  • Maximum Width: 12 inches
  • Maximum Length: 12 inches
  • Maximum Height: 12 inches
Please note that your bot will be checked for weight and size specifications as well as mobility before being admitted. You will be given the chance to modify your bot's weight and/or size if it exceeds the weight limit and/or the size limits. Bots that fail to meet these specifications by the end of the Check-In period will not be allowed to compete.

Failure to adhere to the following guidelines will result in disqualification:
Mechanical: Robots must be purely mechanical. No use of fluids, chemicals, etc. (aside from the batteries used to power the robot).
Dangerous: The robots must not contain parts that might be dangerous if the robot is picked up. For example, there should be no edges that are sharp enough to cut someone from casually picking up the robot.
Operation: The robot must not operate in a way that will have a significant chance of damaging another robot or a bystander.
Other constraints: No robot shall be at odds with the intent of good sportsmanship.
Construction: Bots may be ready made or built by contestants.

BOTS for 6th Grade thru Adult

Construction Operational Mode, Weight and Size:

All robots should be designed and built by an individual or team. The competition category for teams will be determined by the grade level of the oldest member. See below for design guidelines for each game:

Autonomous Play - Noodles & Meatballs
  • Maximum width: 18 inches
  • Maximum length: 18 inches
  • Maximum height: 18 inches at the start
  • No weight restriction since robots will not be in contact with competitors
  • One brain per bot
  • Maximum motors: 6
  • No transmitters or communication beacons (other than GPS). No tethers to laptop or other device during competition. Everything needed for the vehicle's navigation/processing/sensing must be attached and part of the vehicle itself. Operation fully autonomous.
Remote Control Play - Yahtzee
  • Maximum width: 18 inches
  • Maximum length: 18 inches
  • Maximum height: 18 inches at the start
  • Maximum weight: 4 pounds. Robots will compete two at a time and will likely be in contact.
  • One brain per bot
  • Maximum motors: 6
  • All function for this game is remote control; however, it cannot be tethered during play.
Please note that your bot will be checked for weight and size specifications as well as mobility before being admitted. You will be given the chance to modify your bot's weight and/or size if it exceeds the weight limit and/or the size limits. Bots that fail to meet these specifications by the end of the Check-In period will not be allowed to compete.

In addition to the size/design limitation failure to adhere to the following guidelines will result in disqualification:
Mechanical: Robots must be purely mechanical. No use of fluids, chemical, etc. (aside from the batteries used to power the robot)
Dangerous: The robots must not contain parts that might be dangerous if the robot is picked up. No edges or functions that could be damaged another robot or injure a bystander!
Operation: The robot must not operate in a way that will have a significant chance of damaging another robot or bystander.
Interference: The robot must not interfere with the operation of other robots
Other constraints: No robot shall be at odds with the intent of good sportsmanship.
The Head Judge's decision is final. If you have a concern with some element of your robot, you may request a preliminary ruling so that adjustments may be made during the check-in period.

Course Dimensions and Game Design

5th Grade and Under-Remote Control

PING PONG MANIA

Robotic ping pong competition where two competing robots attempt to push as many standard ping pong balls into their 10x10 inch building block (Lego) base square "goal", with a 1/8-inch edge of block to keep the balls in the goal. The arena for the contest is 95-inch by 45-inch, rectangle with 1 1/2-inch-high sides, and the time given for each rounds is 1 minute. Your goal is to create a robot that can gather more balls into your goal area than the opponent. A bot may not "steal" balls once they have entered their opponent's goal. Contestants will be disqualified if they enter their opponent's goal. Robots will launch from the corner opposite their goal.
Judging: A match judge and timer will oversee each round. Disputes will be resolved by a chief judge whose decisions are final. The chief judge, consulting with the match judge, may determine whether replaying the match is necessary. In this case, the entire 1-minute match will be replayed. One match between bots will have a total time of 1 minute, unless extended by the judges.
Starting: Upon the judge's instructions, the two teams will start movement of their bots upon release of 25 ping pong balls by the referee. The contestants' bots will be positioned on the arena in a way which will result in their goal being at the opposite end of their start position.
Scoring: A robot earns a point for each ball gathered into their goal. The robot that earns the most points, within the time limit, shall win the match. If there is a tie for the number of balls corralled, balls will be restarted by the judge for a 1-minute tie breaker rounds. Robots that enter the goal area of the opposing team will be disqualified.
Stop, Resume: A match stops and resumes at the judge's direction.
End: The match ends at the end of 1 minute and the tally of points by the judge. The two operators will retrieve the robots from the competition area.

Roll The Dice

Robots may be designed and built by individual or teams. The robot must function as an autonomous vehicle (no remote control allowed). A successful run is one where the vehicle navigates from a starting line and pushes or carries up to 4 foam dice, measuring 2 1/4 inches into either 7in x 7in marked corner zones and then returns to the start/finish line to park within 2 minutes. Bonus point may be awarded if bots can compete special skill during the run, such as but not limited to sounds, lights or dance. Contestants can earn bonus points even if they are unable to complete the run during the time limit.

Scoring - Contestants will run one at a time. Robot may be placed anywhere behind the start/finish line to launch. Time will begin when bot crosses the start line. Time allowed for this contest is 3 minutes. Bots may be picked up and restarted: 1st time=no penalty, 2nd time=25-point deduction. Dice (2 1/4" foam) may be placed in either goal area but must end up fully inside the goal boundary.
Points:
10 - Demonstration of a special skill (possible examples sounds, lights, dance moves)
25 - For each successful foam dice placed inside one of the 7-inch x 7-inch corner goals
25 - For ending the round with bot stopping behind the start/finish line at either end of the playing field.
Each bot will make 2 runs and scores will be combined. If there are ties among the top scoring teams/individuals, there will be a 3rd tie breaker round to determine 1st, 2nd, and 3rd place finishers.

The Team/Individual with the highest score will be awarded TOP BOT trophy.

6th Grade and UP - Remote Control

Yahtzee

Description
Two robots will compete head-to-head on the game field. First Round pairings will be done by drawing numbers. Robots will launch from diagonally opposite corners. Thirty 2.5" foam dice will be spilled into the center of the game field. Robots will move dice into their safe zone to create sets: 3 of a kind, 4 of a kind, full house, straight (series of 5), 5 of a kind, within a 2-minute time limit. If the value needed is not showing, dice may be flipped by the robot to attempt to gain the needed value. Dice may not be stolen once they are in the safe one. Teams/Individuals may not hoard dice that are not being used in point sets. Point values will be tallied at the end of a two-minute round. The winner will advance to the next round of competition. Ties will be broken with a one-minute tie-breaker round.

The Preparation
  1. Teams/Individuals are expected to make all the necessary measurements, adjustments and sensor readings before the event starts. If you are not ready to bring your robot to the starting line when called, you will forfeit your run.
  2. Allowances for unforeseen delays will be taken into consideration but will be up to the contest judges. Please notify the judge immediately if you have an issue that prevents you from competing on schedule (repairs, bad code, gremlins, or dead batteries do not count). Be prepared for anything.

Course Design

The field is a VEX Portable Competition Field Perimeter (276-8242) with VRC Anti-Static Tiles. Approximate internal dimensions are 140"x140"x12.25".

The Safe Zone will be a 5-inch strip along the wall at the back of the launch point. Entering the opponents Safe Zone will result in disqualification.

To launch, robots will be placed in diagonally opposite corners. Judge will drop 30 2.5" dice into the center of the playing field. Judge will start the bout with a 2-minute time limit. Bots will retrieve dice from the center to build scoring sets (see Scoring for a full description) within their Safe Zone. If the value needed is not showing, dice may be flipped by the robot to attempt to gain the needed value or return to the center to retrieve a die with the needed value. Dice may not be stolen once they are in the safe zone. Teams/Individuals may not hoard dice that are not being used in point sets. Point values will be tallied at the end of two-minute round. Dice that are sitting within the Safe Zone but not in a scoring set will result in a deduction of points equal to the value on the dice. The winner will advance to the next round of competition. Ties will be broken with a full reset one-minute tiebreaker round.

Scoring
3 of a Kind: Sum Total of the set of 3 matching dice
4 of a Kind: Sum Total of the set of 4 matching dice
Full House (a pair AND 3 of a kind): 30 points
Straight (sequence of 5 dice): 40 points
5 of a Kind: 5 matching dice - 50 point
Penalty: Point deduction of dice value that are in safe one but not in a set
Disqualification for entering Safe Zone of opponent

6th Grade and Up - Autonomous Control

Noodles & Meatballs

Description
Robots may be designed and built by individual or teams. The robot must function as an autonomous vehicle able to navigate the game course. Contestants will have 2 minutes to move up to 4 noodles from the peg on one peg board to the corresponding peg on the opposite peg board and gather up to 5 meatballs for placement in goals to accumulate maximum points.

The Preparation
  1. Teams/Individuals are expected to make all the necessary measurements, adjustments and sensor readings before the event starts. If you need to wait for GPS lock or a setup routine, you will need to do this before the run begins. If you are not ready to bring your robot to the starting line when called, you will forfeit your run. There will be two rounds of competition, and competitors will be called in the same order for both rounds allowing time for repairs or adjustments between runs.
  2. Allowances for unforeseen delays will be considered but will be the decision of contest judges. Please notify the judge immediately if you have an issue that prevents you from competing on schedule (repairs, bad code, gremlins, or dead batteries do not count.) Be prepared for anything.

Course Layout and Obstacle Breakdown (all measurements are approximate)

The field is a VEX Portable Competition Field Perimeter (276-8242) with VRC Anti-Static Tiles. Approximate internal dimensions are 140"x140"x12.25"

Each round of play will be 2 minutes in length. Two robots will complete simultaneously (R1 and R2) with rear against the wall at the 3 and 9 positions. Robots will operate only in their half of the field, designated by the red dotted line (a physical barrier [2"x10"] will divide the playing field and prevent interference between robots.) Robots will score points completing a combination of two skills. By removing noodles from pegs (1A or 2A depending on side) and transferring them to the opposite peg at 1B or 2B. Points are awarded for removal of the noodle, placement of the noodle on the designated peg, or a lesser amount if in the area but not on a peg. The second skill is to move the "meatballs" by pushing into a box with a side opening or lifting the "meatball" into the basket with a top opening. Operators may complete the tasks in any order and in any combination to gain the maximum points (See Scoring) After completion, robot should return to starting position.

Various rules for all games

In addition to the main set of rules, there are a few other rules that must be recognized for the safety and fairness of all participants:
  • Intentional damage or alteration of the arena's surface is prohibited. Mechanisms on your bot that can harm or alter the arena's surface are prohibited; any bot that the judge deems harmful to the arena will be disqualified.
  • Intentional damage to the opponent robot or the robot arena is prohibited. Robotic ping pong is a game of pushing, not destruction. Everything from flame-throwers, to sharp objects, to liquids, to bombs are absolutely and entirely prohibited.
  • Your bot may not intentionally drop any piece(s) or any other object on the arena's surface. Anything that may be dropped on the arena, intentionally or unintentionally, will be immediately removed. Note that pieces that accidentally come off the robot and land off of the arena do constitute the robot leaving the arena.
  • Electronic interference is prohibited. This includes, but is not limited to, flooding the arena with infrared rays, or broadcasting other electromagnetic interference.
  • All participating bots must possess a form of mobility and use that mobility during play. Immobile bots will not be admitted, and bots that do not use their mobility during match play will be termed disabled and removed from play.
  • A false start in a match (pushing the wrong button on your robot or beginning too soon) will result in a restart for the first fault. A second false start will result in forfeiting the round.
  • If, at any time, the judge decides that a participating bot should be removed, the judge has the right to disqualify that bot. This can be due to harmful violence, disregard for the rules, or any other reason that the judge declares.
Tournament Play: For the first two rounds of competition, teams will draw a number for bracket placement. The third round will begin the elimination round and placement will be based on total score from Round 1 and 2. Each team is guaranteed a minimum of 3 matches.

These rules are subject to change for clarification. Please check for updates, posted here. Questions may be emailed to office@wilsoncountyfair.net
