 * The Mayan Challenge II - StringBot in King Ixtua's Tomb **

King Ixtua liked small spider monkeys. You got past one of his traps with ExploroBot. Now you have a new challenge in the tomb. Thank goodness for your NXT Mindstorm. It's still smaller than a spider monkey – and easier to train (Yes?)

OK, you got the door to the tomb to open to the throne room, but the floor across is booby-trapped. To deactivate the traps a monkey was supposed to go on a vine looped over a hook on a beam across the room and drop pebbles into a vase until the weight of the vase deactivated the traps. You have no monkey – but you have good, ol’ NXT and some rope, with which you easily lasso that hook.
 * Problem **

**Your Mission** – yet again, NOT impossible – and which you must accept ;-) Design and build a robot that can crawl along the rope (while carrying a pebble) until it’s over the vase and then drop the pebble in the vase and return back for another pebble.  Complete the three discussion questions on this page and meet the challenge.  The first team to succeed (and complete the Discussion questions) gets 5 points towards their final score. The second team gets 3 each and the third team gets 2 each. Good luck!

The throne room is about 10' x 10'. It is fairly dim and very quiet.

Build your own robot or use the [|StringBot example]
