I just wanted to share with you some images of our team’s shooting mechanism. I’ve spent a lot of time modelling it and am proud to display the (virtual) fruits of our team’s many hours of designing and testing. Enjoy!
A cim 1:1 might have a lot of speed but not a large amount of torque our team is using a simulator to run our shooter same wheel geared for power and is doing pretty good. Do yall have a tight compression?
As chris described, the pneumatic wheel has plenty of mass to result in a big moment of intertia (flywheel effect) as long as it has sufficient rotational energy when the disc contacts it, we are good. The 40’ I gave you is a real-life test.
Great CAD model. One thing I noticed that I don’t like: 80-20. That stuff’s very heavy. I would advise replacing those cross-members with angle or something. It would be thinner, MUCH lighter, and just as strong.
Other than that, great design!
That looks like a really neat harvester idea! Looks like it could be quite effective and elegant!
As a recommendation (that I’m sure you’ve thought of): make sure it’s relatively easy for a driver to approach and pick up a disc… as with prior years and game pieces, a harvester’s usefulness is often limited by ability to receive a game piece easily. Most often this means making the harvester/mouth as wide as possible…
About the function: The stack of frisbees has a slot cut in the side, when we are ready to fire, an device of some kind pushes/pulls the frisbee into contact with the shooter.
About the 80/20: I agree, its heavy stuff. The thing is we need the adjust-ability because features such as the gearbox and several other points are fixed to 80/20 to allow us precise tuning over the pressure of the wheel-disc-guide dynamic
That said, we are looking at using a lighter material to supply the structure for those members, but attaching very short segments of 80/20 where we need the adjust-ability.
