    Rope Climbing and Can Crushing at BrickBots.Com —Richard Sutherland
   Hello All, On Friday February 9th, 2001 the Rope Climbing Contest at BrickBots.Com finished with three completed entries and one standout winner! The contest objective was to build a LEGO robot to go up and down a length of rope as quickly as (...) (24 years ago, 12-Feb-01, to lugnet.robotics)

     Doesn't a machine that does nothing score perfectly? If so, my entry is an RCX sitting next to three cans. It finishes the instant it starts. You have a formula time * height * bonus = score, with small being better. So a robot that does no crushing (...) (24 years ago, 13-Feb-01, to lugnet.robotics)

   (...) I don't have the time to work on this, but I see a relatively simple way to do this that might work well. Build a column to stack all 3 cans into. Place 3 "spikes" roughly dead center at each can, the RCX powers a bar that moves the spikes in (...) (24 years ago, 13-Feb-01, to lugnet.robotics)

   (...) [SNIP] (...) Good idea, but the rules specify that the robot can not start with a store of human provided potential energy (Aside from the batteries in the RCX if you want to be technical). The large weight waiting to drop would be a bunch of (...) (24 years ago, 13-Feb-01, to lugnet.robotics)
