Rope Climber has been built for the rtlToronto Lego Robotics Event – Rope Climbing.\u00a0 In a nutshell – build a robot that can find and climb a rope.\u00a0\"\"<\/a> Sounds easy right?\u00a0 Not!\u00a0 In the tradition of rtlToronto, there are some interesting rules to make this more challenging.\u00a0 First off – the robot must fit within a 8x8x8 square on start.\u00a0 The trick – the rope is hanging 12 inches off the ground.\u00a0 The robot must “grow” to catch the rope.\u00a0 The robot must also start 36 inches from the rope.\u00a0 This requires it to be able to drive and find the rope.\u00a0 The 8 inch requirement also is important to consider once the robot reaches the top.\u00a0 In order to win, the robot must be above a marker placed on the rope.\u00a0 This marker will be 12 inches from the top.\u00a0 This robot extends to 14 inches, so it must also “contract” when it detects it is at the top.

Here is my take. In order to make a winning robot, the following must be considered:
\n :: speed – it must be able to drive to, find and climb the rope the fastest to win.
\n :: grip – to climb effectively, the robot must have good grip on the rope.
\n :: weight – the lighter it is, the faster it climbs.
