These are some pictures of our attachments. The first one is our crane attachment. The long arm pushes the block, the wheel lowers the arm, and the short arm pushes the crane into place. The wheel spins so it won't get stuck. If you look closely at the small arm, you will see a rubber band. It is there because a stiff arm would push the crane too fast, and it would swing. The second attachment is the lift arm. It uses a motor to lift the piece remover up and down to flip the elevator. The final attachment is the block stack holder. It holds our block stacks in place while we push them. Our attachments are actually not attachments, but detachments. That means that they support their own weight. If you put too much weight on one side of a holonomic robot, it will move inaccurately.

This attachment does the crane mission. It does all three things at once, turning it, dropping the block and pushing the other block under it.

The majority of our missions are block stack missions.
