30lb Weight Class

Arena under construction

UPDATE: We have a new ruleset for bot design, starting with our May 2022 event. All bot design rules below will apply until then.

30lb full combat robots are heaviest class we currently fight at NHRL.

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

• 30lbs in a fight ready condition. All robots will be weighed prior to their first match.
• Weight of cameras or video-recording equipment does not count towards the weight limit.
• There is a 12lb 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 8lb 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 30lb this is 33lbs.)
    • If that bot happened to not use wheels or tracks for motion its max weight would be 42lbs, leaving 8lbs for other multibots.
• The weight bonuses may be combined for a maximum total weight of 50lbs (assuming a wheel-less multibot).

Size

• Robots must be able to fit in a 36"x36"x36" Box in a fight ready condition. The robots may expand or contract during the match.
