Rules at 50 Day are similar to many other robot combat events, NHRL Rules tend to be more permissive of exotic and high powered weapons. Judges reserve the right to grant exceptions to any rule. Our goal is to provide fun, exciting fights and a fair playing field. The sprit of the rules is what is more important than fighting to get to the letter of the law. Good sportsmanship is always required.

Bot Design Rules and Limits

Weight Class Specific Rules

Special Rules for Rocket Motors & Flames

Bots that use weapons such as rocket motors, or weapons that include the use of a flame, must abide by additional rules. See the sections on Fire and Flame-Based Weapons and Rocket Motors on the Safety Page.

20 Minute Ready Rule

All robots are guaranteed a minimum of 20 minutes between fights. When there are many bots in event the time between matches may be up to an hour or two between your robots last match and its next match. As the number of robots dwindles the time between your robots last match and next will get shorter. The minimum time it can be is 20 minutes. This time is per bot, not per builder. If you are entering multiple bots it is on you to manage your time. Robots that are not ready will forfeit their matches.

Spirit of the event and the rules

More important than winning or any prize is that the events are fun and enjoyable for all. Short of the weight rule, the rules exist to set the sprit more than a specific worded law. AKA Don't be a lawyer about it. We have a bias to fight robots that show up. If you build something new that you think plays to the edge of rules, show up and tell us why it should be allowed. Odd's are we will let you fight, we love new creative ideas.

Judging

All fights are judged by a team of 3 judges. Judges may be remote and watching via zoom. There is open deliberation between judges after the fight and they will announce their final decisions. Judges are typically ex-competitors and previous bot builders. As the events have grown in scale and scope we continue to work to professionalize the judging. There may be official scores in future matches. Judges primarily are looking for aggression and control of the match. Judges may request a replay of certain sections of a match to assist in judging. Judges decisions are final at this time. Matches in the winners bracket may have a review requested if both competitors agree.

Matches will be judged across 3 categories of equal weight

  • Control - How controllable this robot in how it translates across arena and in how it attacks
  • Aggression - How much does this robot act as the aggressor and dominate the match flow
  • Damage - How much damage does this bot do its competitor.

Fight Rules

Duration 3 Minutes or 3.5 minutes if an encore is called for by the judges.
Knock Out Any robot unable to show controlled motion after 10 seconds is considered disabled and will be considered a knock out.
Tap Out Any competitor can forfeit the match for any reason by loudly banging on the arena wall. This is considered a tap out, and counted as a loss. The other competitor must stop attacking immediately; continuing to attack after tap out will be viewed as unsportsmanlike.
Encore If a match is particularly exciting the judges may poll the audience in the final minute and decide to add an Encore extending the match by 30 seconds. Only one Encore can happen in any single match. Encores only occur in the winners bracket
Hazard If the judges deem a robot to be a hazard to the crowd or a robot is doing sustained damage to the arena, the judges may prematurely end the match at any time. Purposefully destroying the arena may result in a forced forfeit of the match.
House Robots The house robots serve as an in ring camera, and referee that can sometimes unstick and disentangle bots. House robots will unstick stuck robots each once per match. If stuck a second time the robot must unstick itself or it will lose if unable to show controlled motion.
Safety Organizers reserve the right to disqualify any competitor for failing to follow basic safety. All robots with a kintetic weapon should have a weapon lock. The lock should not be removed until both bots are in the arena and the doors are about to close.
Sportsmanship Judges reserve the right to KO or Disqualify any bot or team for unsportmanship like conduct.
Judges Decisions are Final All judges decisions are final and not subject to review.
Be Ready Only 20 minutes of pit time is guaranteed between matches. This usually only comes into play when there are few robots remaining in the bracket. Early on time between matches can be an hour or more.

Tips and Tricks

  • Arrive with a working robot that is ready to fight.
  • Arrive before 9AM to secure a good pit location, get your robot through safety checks early.
  • Bring extra batteries and be ready to swap them quickly.
  • When your robot is ready to fight head to arena area rather than waiting at your pit.
  • Fix your robot before chatting with other competitors.
