M. Nelson, 21 Mar 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.
