Divided in to teams with those teams build a bot that can support its self on a wall in a certain space. It has to pull up a certain amount of weight. Without the bot falling off the wall, or any thing in the cup falling out. We have to supply our own string.
We were able to lift a max of 288 grams.
Program was changed later to 7 seconds.
We tried to use a pulley system but it did not work. So we went to a simple one pulley for leverage.
