Modular bots are robots that can change offensive or defensive features depending on who they up against in the tournament. Repairs and replacing broken components of your robot don't count as a modular robot. If you are changing less than 10% of your robot weight and none of it is powered, it’s not considered a modular robot! Like all other bots you still need to bring it to the green room in its final ready state.
==Example Bots==
You can learn a ton more about past and present competitors at NHRL. Below is the 12lb bot category with information on individual bots.


* [[:Category:12lb Bots|All 12lb Bots]]
* '''No more than 50% of the entry weight (this includes all weight bonuses) budget can change.'''
* All versions of the modular robot must pass safety before being put in the ring.
* If you are taking advantage of a weight bonus all versions of your module configuration must also be able to earn that weight bonus.
* If you bring spare robots your modules must be interchangeable between spares.
* '''Competitors must declare to safety their bot/module/config as soon as the match opponents are chosen.'''
** As soon as you know your opponent report to the green room / safety your chosen config.
** Safety will not disclose this config to anyone.
** You will not be told your opponent's chosen config.
* '''You can only bring entries you intend to fight into the green room. Swapping of modules or bots is not allowed.'''
* Any competitors that have qualified for the finals before July 2021 can keep their legacy configuration and aren't limited by the 50% weight rule. However all other rules apply.

==== Spare Robots ====
Bringing exact duplicate copies of your robot is allowed. In order to count as the same robot spares must be as close to exact copies as possible. This is a common way many competitors speed up repairs. All copies must pass safety before competing. If you are bringing multiple robots in a modular configuration you should be able to demonstrate the modules could be swapped between robots at any time. If you can't, then it doesn't qualify as the same robot.

====Spare Batteries====
Bringing Spare Batteries is HIGHLY encouraged. Bot's get a minimum of 20 minutes in between matches for repair and recharge. Rarely is this enough time to recharge a fully dead battery. Bringing spare batteries is highly recomended!! If you let the organizers know your battery size and connector type one week in advance (contact@50day.io), we will glady provide you with a spare battery for your bot for free. NHRL has a strong prefrence for XT style connectors XT90/60/30.

==Pushing the rules==
These rules describe the absolute limits of what can be done. There is much that is allowed at NHRL that might not be at other events. We actively encourage competitors to think creatively and imagine new robot designs. The following are examples of things are are perfectly legal within the NHRL rules
===You are ALLOWED to do this at NHRL===
*Robots that use fire or heat as weapon
*Robots powered by an internal combustion engine
*Robots that use compressed gasses
*Robots that are made of fabrics or soft bodies
*Robots that will keep fighting even if their batteries are on fire
*Robots that are crusher robots
*Robots that can fly

12lb full combat robots hit much harder than 3lb bots. These robots, while still accessible by amateur and home builders, start to pack a serious punch. In this weight class you can expect to encounter lots of metal and steel. Very few plastic or 3d printed materials can handle the damage these bots can dish out.

Safety

  • All robots must have a weapon lock that prevents any weapons from moving outside of the cage.
  • All robots must have a way to turn off power without disassembling the robot.
  • All robots must pass a radio fail safe test.

Physical Rules

Weight

  • 12lbs in a fight ready condition. All robots will be weighed prior to their first match.
  • eight of cameras or video-recording equipment does not count towards the weight limit.
  • There is a 6lb weight bonus for robots that do not use wheels or tracks for motion
    • For a multibot, only the heaviest bot is required not to have wheels to qualify for this weight bonus.
  • There is a 3lb bonus for competitors made up for more than 1 robot.
    • The robot will be considered disabled when 51% or more of the total weight of the bot is no longer moving.
    • The heaviest robot in any multi-bot setup must have an active weapon
    • The maximum weight of any one bot is 110% the weight class limit (for 12lbs this is 13.2lbs.)
      • If that bot happened to not use wheels or tracks it it's maximum weight would be 19lbs (13+6lbs)
  • The weight bonuses may be combined for a maximum weight of 19lbs (assuming a wheel-less multibot)

Size

  • Robots must be able to fit in a 30"x30"x24" Box in a fight ready condition. The robots may expand or contract during the match

  • The following weapon types are prohibited:
    • Nets
    • Projectiles over 150mph
    • Liquids of any kind
    • Weapons which purposefully disrupt radio signals
    • Strobe Lights
    • Lasers

Team Size

  • 4 People Max
