board challenge rules
Board Challenge Rules
  • Start with 2 wheels in Base. (apparatus can hang over line)
  • Bots can return to base (autonomously) for adjustments at no cost. (Any part of the bot over the line – no tethers)
  • PVC parts under bot control can be manipulated while the bot is in base.
    • Bot can push/pull PVC parts back to base and operator can move them to place them back under bot control as it leaves base
  • If Bot is touched it must return to Base. (4 point deduction per occurrence)
  • Black line is “in bounds”. (score points if object is on the line)
    • All of the barrel must be on the line, not just part touching. If any of the barrel is outside the black line, the barrel is NOT in.
