Re: Linear Path Shooter vs. Circular Path Shooter?
 

We did side-by-side comparisons of a 1-wheel round shooter to a 1-wheel straight shooter. The straight shooter is powered directly by a CIM, the round shooter is actually spinning at a 1.5:1 ratio off of a CIM.

They seem pretty equal except for the fact that we have the motor on the round shooter spinning at 150% of what the straight shooter is spinning at.

Can I ask why you're shooting so low?

Robot in 3 days did a linear shooter, and it seemed to have really good accuracy, but the linear shooters also have a larger footprint. On the other hand, it can be fed from an end, and fire out the opposite, whereas the circular path shooter type needs to be fed on a side that is 90 degrees away from the place where the discs exit the shooter. This can make storage and transportations of discs through robots a lot more complex. It really all depends on how your robot is layed out component wise.

Just doing a side-by-side comparison. We just decided to do it at the same height and angle as each other. We were just keeping the conditions of the 2 shooters as equal as possible, no real rhyme or reason for doing it the way we did except for simplicity purposes.

Basic dual belt concept with pivot bar idlers fixed => i.e without any spring loaded swing arms added between idlers & pivot bars. It is explained in detail in this other thread --
