Stacker with a vacuum

[Brett W]

Creating a vacuum with the cylinders is very easy. Start by pushing the rod all the way into the cylinder. Now, put your thumb over the lower port and pull on the rod. Notice that your finger gets sucked in a little? That's a vacuum!

Don't forget your team can do anything you want before you read this. Once the air cylinder is fully extended you lose a little of your suction power causing the amount grip to decrease and then it is easy to knock the bin off of the suction cup. There is another way. Our team figured it out and is making it work, But that is a secret. You could try the cylinder idea if you like i haven't tested it but our mentors say that it probably won't work.
