FRC 2012 Ball Launcher Trajectory Testing by iR3 Creative

Building off our last video seen here: http://youtu.be/DO0XzkthMUs

The top of the shooter is 57" and distance measurements were taken from the front of the shooter to the backboard.

We designed this basket ball launcher to test shooting concepts on the fly!

We decided to test some of the best trajectories for long distance shots. Early testing is showing that line drives are difficult to make bouncing off the backboard. Higher trajectory shots are proving to have a higher % of makes because they strike the backboard with less forward velocity.

Also notice that we have turned our shooter horizontal for the most recent tests, we have not yet determined the advantages or disadvantages of either configuration.

@vigilantice CIMs are running the rollers but the could as well be Fisher Price with an AndyMark FP planetary. The motor is mounted to a Modulox Lunchbox gearbox with a 14 to 40 tooth gear reduction.

is the table 5ft from the ground

@straub110 The top of the shooter is at 57" so roughly 5' from the ground.

About how much "pinch" did the design have? As in what was the distance between the two wheels? Great design prototype, though. Thanks for all the help you're providing to teams!

It works okay. . .

I think if you could get backspin on the balls it would sink right in on those angle 2 shots, the best way I've found is to mount the wheels vertically and modulate the speed of them

Have you guys thought about using only 1 set of wheels instead of two so as to lessen the inaccuracy of the shooter?

[vigilantice]

are those cims running the rollers? Are they just directly driven or is there a gearbox?
