(...) This may be construed as nit-picky, but I believe the spirit of the game will allow the bottom-most part of one's robot to be above where the 11' mark was, or would be if the rope were still hanging straight down. Am I right? I consider (...) (21 years ago, 23-Feb-04, to lugnet.org.ca.rtltoronto)

(...) I agree that spooling is a valid strategy. There are two goals to having the robot within two marks: a) Definitively saying if you've "made it". b) Ruling out people who might leave a portion of the robot behind. I want to hear additional (...) (21 years ago, 23-Feb-04, to lugnet.org.ca.rtltoronto)

I'm thinking that the electrical tape may be too slippery to be grabbed by the 'bot? 2, What if we install some type (...) (21 years ago, 23-Feb-04, to lugnet.org.ca.rtltoronto)

(...) The is why Chris' makes a good point when he says the winning robot should be the one that hits the top mark first, not passes the lower mark. If a robot is spooling there is no way to tell when it passes the lower mark. So if we say you must (...) (21 years ago, 23-Feb-04, to lugnet.org.ca.rtltoronto)

I have no problem with spooling. it would be a valid way to solve this. maybe an easier way to phrase the rule set would be to read: -your entire robot must be higher then 11 feet off the ground. this would allow spooling, and make sure people life (...)

(...) I think "spooling" would be quite difficult. First, grabbing on to the rope is not a trivial task. Second, the more you gear the "spool" down, the more counterweight you need to deal with the "gerbil effect", meaning you want the spool to turn (...)

A couple of suggestion on the proposed rules: "The rope will hang roughly 12" from the floor." I think this needs to be a more exact measurement...because of the reaching-up aspect, the differerance between 11" and 13" could be the difference (...)
