I don't know exactly what Bimba is offering for teams this year. The cylinders in this design are 1 1/6 bore 14 inches long. Technically anything longer than 13 inches should work, you would just be using more air per lift than you need. You could also put stopper blocks (pvc pipe) on the shaft to limit the stroke if only longer ones are available. The ones I used in the design were from Mcmaster http://www.mcmaster.com/#standard-air-cylinders/=vd6415

Thanks!
All parts are in route to AndyMark from Texas, I expect extrusions, plates, bushing and all the parts to be in stock by the weekend at the latest. We will keep doing our best to keep up with demand. We appreciate everyone's patience with this, and if you have any questions I will always be available to help.

How far inside your robot is really a factor of how many totes you want to stack and what amount of control you want to have of the totes as you drive around. If you have them all the way outside your robot, making turns at fast speeds become problematic. The other reason why in this design I only did it half way (besides accommodating the Kit chassis) was to make it so you don't have to drive on the scoring platform when placing totes.
