There are specific pneumatic cylinders ("Linear Actuators" isn't their correct name) that you are permitted to use. Look for the FRC link at
www.bimba.com
Basically, you can choose whatever you want from the list of permitted cylinders. These come in varying lengths, and in diameters of 3/4", 1.5" and 2". Look in a
previous year's pneumatics manual if necessary, but remember to follow THIS year's rules. YOU need to decide what amount of force is necessary, and how long it needs to be.
Think about the problems and compromises:
Large cylinders are more powerful, but use more air.
(You have an air budget, just like an power budget. That's not a big compressor...)
Small cylinders move faster, but are not as powerful.
Long cylinders need more than twice their 'throw' in distance to fit. A 24" cylinder ends up something like 50" long when extended.
I was thinking: Since you're down under, your robot won't have any trouble flipping back up if it turns over, right? (Or will it run upside down here in the 'states?)
