SPARC Judging Guidelines v1.2:

Damage (4 points): Functional impact by match end

• Engagement: Who dictated the flow of the match (combines aggression/control)
• KOs, Tap‑Outs, Count‑Outs
• KO= 10‑second immobilization or tap‑out
• Judges’ decision only if no KO at the horn

Arena

• Hexagonal arena, 3 ft sides, 3 ft walls
• Plywood floor with grip texture  
• Fully enclosed with 6 mm polycarbonate

Safety Requirements

• Power switch or removable link
• LED indicator for robot power
• Weapon locks must be clearly visible and effective whenever outside the arena
• Batteries must be charged in firesafe bags
• All bots must pass safety and weight inspection
• No spin‑ups or destructive testing outside the arena

Costumes

• Bring the Halloween spirit! Builder and robot costumes are encouraged.
• Contests will be held for Best Bot Costume and Best Builder Costume.
• Bot costumes removed before fights do not count toward weight.
• If a bot costume stays on during fights, it counts toward weight and must not pose an entanglement hazard.
• Personal costumes must not impair vision or mobility, and must not risk knocking over equipment. Keep it spooky, not unsafe.
