Examples: Every wheeled or tracked robot out there. Also Mongus and Little Slice
Robots that rely on a thrust method other than mechanical friction with the floor (such as thrust-generating fans, electromagnetic interaction with the surroundings, or reaction forces from gas jets or hurled projectiles), will not be considered walkers or shufflers. This is true even if the robot rests on an air cushion or skids rather than wheels.
Robots that float or fly are not allowed. Hovercraft robots are allowed, but are subject to wheeled weight limits. A jumping bot that has no wheel driven locomotion and otherwise conforms to the walker definitions may receive the walker weight bonus. Keep in mind, the controlled movement and minimum speed requirements must be met.
Shufflers may weigh up to 50% more than their standard class weight limit.
Examples: Phelan, Nemesis, Pressure Drop, Son of Whyachi, Reflex, Belladonna, Kung Fu Cow
Walkers may weigh up to 100% more than their standard class weight limit.
Examples: Mechadon, Snake, Lock Nut Monster, Ixion, Lurch
If you are unsure which category your design falls, please email a detailed diagram of your design and a detailed explanation of its mechanical principals to firstname.lastname@example.org for approval before building.
All 12 lb and heavier bots must be capable of a linear speed of 16 feet per minute. This requirement must only be met during initial inspection. This rule is not a means to disqualify any competing bot or to determine the winner of a bout.
A 12 lb multibot consisting of a Roller/Walker is allowed 12lbs
total. A 12 lb multibot consisting of a walker/shuffler is allowed
18 lb. A 12 lb multi-bot consisting of two walkers receives a 24lb
Example: A 12 lb bot may not be entered in the 12 lb bracket AND also as part of a 30 lb multi-bot.
The rules listed below are not exhaustively written to account for every possible circumstance. We will do our best to explain our intent, and it will be your job to remain within that intent. If we feel that a design or feature is exploiting the intent of the rules or the spirit of the class, we will disqualify it without hesitation. Certain requirements or limitations are intentionally vague. You should not design your bot to push the limits of the rules. But rather, you should intentionally build with the following simple guidelines in mind:
AM radios are only allowed on 150 g or Ants with non-active weapons. Active weapons include, but are not limited to, lifters, spinning weapons, actuated spikes or hammers.
AM is not allowed on 150 g or Ants with active weapons, or on any 3lb or heavier bots.
Failsafes are recommended, but not required on 150 g and Ants without weapons.
All 3 lb and heavier bots must have a failsafe for weapon and drive. When the drivetrain and weapon are powered and the radio transmitter is then turned off, the drive and weapon must come to a stop and remain motionless.
Having two or more frequencies available is STRONGLY recommended. If alternate frequencies are not available and a conflict arises, one robot may forfeit voluntarily or a coin toss may be used to determine the winner.
Radios may not be turned on for any purpose without obtaining the appropriate frequency clip from the frequency board.
A single switch or removable link is preferred, but two switches/links will be allowed if they are easily accessible.
The judges reserve the right to disqualify, at any time, any robot that poses a threat to anything other than the arena surface or its opponent(s). If you have a questionable design, please consult with NERC before constructing your robot.
Weapons must have a safety cover on any sharp edges.
Weapons that could harm a person outside the arena must have some kind of mechanical locking device in case of accidental activation.
There will be absolutely NO testing of robots outside the enclosed arena. Robot weapon testing MUST be carried out under the supervision of a NERC official with the appropriate frequency clip.
Robots running pneumatics or hydraulics must stay within the specified ratings of the system parts. Documentation and proof of operation will be required. A gauge to display operating pressure is required. All pneumatic and hydraulic systems must be approved by a NERC official. Contact NERC PRIOR to the event with your system's specifications.
Banned weapons include:
Tethered projectiles are allowed with a maximum tether length of 4 feet.
and the Arena:
Each driver may only enter one bot per weightclass. A team may enter unlimited bots per weightclass, as long as there is a dedicated driver for each bot.
The arena, at a minimum shall be a painted plywood surface, surrounded by a four-foot high polycarbonate shield. The top will be closed off by a layer of polycarbonate to catch any debris that may try to exit through the top. The arena shall be raised off the ground for visibility.
The 24' x24' arena has a 1/8" steel floor painted with traction paint. It is fully enclosed by 1" thick polycarbonate on the lower 4' and 1/2" thick polycarbonate above that.
150 g and Antweights will fight on an arena insert that is 4'x4' and raised 6" off the floor of the host arena. There will be 12" openings centered along each wall to allow antweights to be pushed out of the arena to the floor.
Any robot, which comes into contact with the floor outside the arena, will be declared defeated.
At the start of a combat round, all electric motors must be stopped. Any exposed rotating devices must be stationary.
During combat, no part of the operator's body or their remote antenna or any other device may penetrate the arena surfaces during combat. Interfering with a combat under way will be grounds for immediate disqualification.
After a match is over, any dropped or thrown objects must be cleaned up, by the operator responsible, to the best of their ability.
It is expected that the arena surface may become damaged during the course of the competition. Plan your robot's drive system accordingly. Being hung up on a damaged or irregular spot in the arena will count as immobilization.
The Officials reserve the right to declare a match over at anytime. The word of the officials is final.
If a burning robot is judged to pose a threat to the audience or arena, the match will be paused until the arena is made safe. If the robot is still mobile, the match will be continued. If it cannot be extinguished to the satisfaction of the officers, it will be declared defeated, even if still mobile.
A competitor will be declared immobile if it cannot display linear motion of at least one inch in a timed period of 30 seconds. A bot with one side of its drivetrain disabled will not be counted out if it can demonstrate some degree of controlled movement. A bot that is completely motionless will be KO'd after a 10 second count.
If a part of another robot becomes entangled in its opponent and cannot be freed within 15 seconds, the match will be paused until a NERC official removes the entangled piece
A bot may not lift, hold, or pin its opponent for more than 15 sec.
Separate winners will be announced for each event (combat, and melee). Competitors are not required to compete in all events.
Format of combat rounds will be double, or single elimination depending on the number of competitors. This will be announced at the beginning of the competition.
Not all weight classes will be represented at every event. Weight classes that will be competing will be announced prior to the event.
Example: An event may consist of Antweight and 12lb bots only, or 12lb and 30lb bots only.
The format of the event and weight classes will be spelled out along with any other information needed in the event guidelines. These will be emailed 2 weeks prior to the competition to all registered competitors. Please be on the lookout for this as it will contain necessary information such as arrival times, check-in procedures, etc.
Due to insurance concerns, Minors under the age of eighteen attending a NERC event without a parent or guardian may be required to complete a special release. Please contact NERC for further information.
