Rules 2001

The rules for the '01 Savage Soccer competition are given below.

If you have any questions about the rules, please email the mini-FIRST alias ( as specified in rule #15.


  1. TIME-OUTS: Each team will be issued 5 Time-out tickets, each labeled "Team#__ Time-Out 1 Minute", which must be presented to an official to be activated. No extra tickets will be given (when you're out, you're out.) The 1 minute tickets may be used individually or in succession (present 2 tickets for a 2 minute time-out).
  2. The Official Parts List is now on the website. Notice that the Radio Shack Limit IS indeed $10, allowing for the purchase of ONE motor. (Reminder: Receipts must be provided at check-in, limit DOES NOT include tax.) Also, the list states ONE paper towel tube, not TWO.
  3. The Golf Hills are 14" in diameter, smoothly tapered to a 3" diameter flat circle 1 3/4" tall at the center, and the hole is 2 1/2" diameter (Just large enough for the Power Ball to fit snuggly into).

Savage Soccer

A mini-design contest - 2001


To design and build a radio-controlled device that will defeat your opponent at Savage Soccer.

Each team has 10 Ping-Pong balls (~1.5 inches in diameter) of their color (red or white) on the field that they can collect and place in their assigned “Delta Goal”, or in a “Golf Hole”. A single “Power Ball” (~2.75” in diameter) will also be located in the center of the field. The winner is the team with the highest score at the end of any match. In case of a tie, the tiebreaker rules will come into effect. Each match will last two (2) minutes. With four (4) people to a team, each thirty (30) seconds, the drivers will rotate such that all four (4) team members drive for thirty (30) seconds of the two (2) minute match.


All scoring will occur at the end of the 2 minute matches after all balls have come to a rest.

Base Score

Each Ball in the wrong Delta Goal (white ball in red goal or vice versa) = 0 points


Golf Hole Multiplier: Base Score Points times N where N = # of Golf Holes used (balls of your color inside the Golf Hole at the end of the match). Power Ball does NOT count as a used Golf Hole, however your color balls under it do.


Overall Design

The provided chassis (black plastic frame, motor, axles, wheels, electronics, etc.) must remain undamaged and with no permanent modifications. The lexan cover may be modified in any manner (e.g. drilled, glued, cut, etc) providing:

All added features to the chassis and the entire lexan cover with any added features must be easily and quickly removable from the stock chassis. During the competition, teams need to be able to completely remove their apparatus and reinstall it onto a separate chassis within 5 minutes. The remote control unit (transmitter) may not be modified in any manner.


Unless otherwise specified, an unlimited quantity will be allowed from the authorized materials list. (The $10 worth of Radio Shack materials does not include tax.) With the following exceptions, each team's entry must be constructed solely from authorized materials provided by the school or procured by the team from the authorized materials list:

Energy Sources

The energy used by the devices in the competition must come solely from:


At the start of each match, every part of the machine (with the exception of the stock antenna) must fit, unconstrained, within a cube 12 inches on each side. The position of the machine when tested to fit within the 12 inch cube must be how it will be positioned at the beginning of the match. The robot must be fully self-supported, in contact only with the horizontal surface of the playing field when started.


Each machine's weight must not exceed 5 lbs.


Teams will be removed from the tournament only after they have lost 2 matches.

Elimination Matches

In case of a tie during any of the matches, the following tiebreakers will be put into effect:

  1. Power Ball is on your side of field.
  2. Most balls of your color moved from their original position.
  3. Most number of balls in a scoring position.
  4. Closest robot to Power Ball

Safety and Rules Details

  1. At the start of the match, each team may position their robot anywhere they wish, as long as at least two (2) wheels are within their delta goal's white arc. (see field diagram).
  2. If a ball is knocked out of the playing field, a member of the team whose ball was knocked out may retrieve the ball and give it to a judge or instructor who will replace it back on the field nearest to where it left the field, but not in a scoring position.
  3. Judges and/or instructors will disqualify any device that appears to be a safety hazard.
  4. A machine may not intentionally contaminate the playing field or an opponent's machine with lubricants or other debris.
  5. You may interact with your machine during a match only through the normal operation of the remote control system.
  6. Damaging the playing field, the playing pieces or the control system may result in disqualification upon judge's discretion.
  7. The Puh-twang Rule: Any machine that becomes "stuck" in the field of play may be nudged into an operational position by a judge. In such circumstances, the respective driver must announce "stuck car" to the judges, who will, after waiting five (5) seconds, nudge the car.
  8. Strategies aimed solely at the destruction of, or damage to, an opponent's machine are not in the spirit of the competition and will not be allowed. Any contestant who deliberately causes an opponent's machine to fall from the playing field will be disqualified. Devices designed to tip the other vehicles are prohibited.
  9. If any part of a robot reaches outside of the playing field it may be disqualified.
  10. A machine must be designed to operate by reacting only against features within the confines of the playing field perimeter wall.
  11. Gaining traction by use of adhesives, or by abrading or breaking the surface of the playing field is not allowed.
  12. Any team may be asked to reassemble their robot onto a different chassis. They may be disqualified if this takes longer than 5 minutes.
  13. If a team is being pinned for 5 seconds, the team doing the pinning must back off at least 6 inches before they can resume. Failure to do so may result in disqualification. Definition of Pinning: The other car cannot move (jammed into an obstacle), either forward or backward because of your car's presence.
  14. All parts of a machine must stay attached and must not cause any entanglement. Minor pieces becoming detached will not be grounds for disqualification if the judges determine that it 1) was not intentional, 2) did not positively influence the respective team's outcome, or 3) was not the result of improper design/construction.
  15. All questions or rules clarifications will be addressed to the judges via the mini FIRST email alias ( All answers will be posted through the email alias ( Teams are responsible to update/clarify this written guidance through frequent reference to this alias.
  16. Part replacement is allowed between matches if something breaks as long as everything still complies with specifications and rules. Any replacements shall be brought to the attention of a judge before the start of their next match.
  17. Drastic changes to your car may be made between matches, however, items may only be removed, they may not be added. Any modifications shall be brought to the attention of a judge before the start of their next match.
  18. Teams must have their team number visibly marked on their robot (not the chassis).
