Arm mechanism

I would be very, very worried if I were you and planning on using pneumatics to lift the ball up that high. There simply isnt enough air there to continuously hurdle.

in my experience u have to clean ur rollers often, or they will "lag" or stutter. maybe a lead screw. thats what we used on our robot last year to telescope are arm. it worked very well and was pretty quick.

Fortunately you don't have to continuously hurdle, you pretty much have to make a 10 to 15 second or more lap between hurdles. Which seems to be plenty of time for the compressor to catch up.

Of course we're only planning on having to move about a pound or two of metal up about a foot to shoot, the ball has to move the rest of the way on it's own!
