Check out the Spinning Tongues of death.

And yes...

it is completely safe.

Stay tuned for another video of the kicker operating completely attached to the robot along with its functioning pneumatic actuation

here is a more in depth explanation of how our kicker works

Nice.. Easy way to keep the ball from going in past those 3 inches.

The gate keeps the ball from going in too far and the pneumatics and the fact that the entire kicker system is on sliders allows it to slide out of the gate and back in in a split second to make the kick.

Is that your school band playing the background music?

yes it is. The song is called Folk Song Suite

Cool design, but...

and I haven't been following the Q&A that closely regarding this situation...

Do those flappers extend past your frame? From one angle in the video, it looks like they do.

The video was just a prototype. The final design only extends outside the frame for less than 2 seconds

I know on our robot, we have constantly spinning intake rollers. They work great but they overheat the motor pretty fast. Just make sure your motors don't get too hot. Looks nice though

You should probably check on this...
I believe the issue is that you can extend outside the frame but you cannot do it again until 2 seconds have elapsed... Unless you have a really slow moving kicker it would appear the you extend outside your frame more than once every 2 seconds.

Rule <R16>. states that no part of your robot can extend beyond the vertical projection of your frame perimeter during the match except as allowed in <G30>

The pertinent part of <G30> is: BALL Interaction Volume – Solely for the purposes of interacting with a BALL, MECHANISMS that are below the BUMPER ZONE may extend up to the BUMPER PERIMETER, for a period not exceeding two seconds. After returning inside the FRAME PERIMETER, such MECHANISMS are not permitted to re-extend beyond the FRAME PERIMETER for at least 2 seconds.

If you have a flapper... and it extends beyond the FRAME PERIMETER.. it can't go out again for another 2 seconds...

I love your design and I am just trying to make sure you don't run into something in inspection that could set you back

good luck

looks like a great machine!!

the code will not allow it to shoot again for a full 2 seconds after kicking.

I think the issue Bob is worried about is that, since your flapper is spinning, at some point it will be fully vertical and contained within the Frame Perimeter. When that happens, the last part of Rule G30 takes effect, disallowing any of that flapper from exiting the Frame Perimeter for another two seconds. Which will happen, since the flapper would continue spinning after it reached a vertical position.
Does your spinning device at any point in its spinning reach a position in which the flaps are fully contained inside the frame? If so, you have a problem.

The whole thing is completely inside the frame when the pistons are compressed. The only time the mechanism is outside the frame is when it slides in and out in less than 2 seconds.

What he's saying is when you deploy your kicker and it exits the frame perimeter it is spinning quite fast. And while spinning repeatedly enters and exits the frame perimeter much much faster than 2 seconds in 2 seconds out

The only time the mechanism is outside the frame is when it slides in and out in less than 2 seconds.But when it slides out, don't the paddles of your spinner, individually, exit and return to the frame perimeter multiple times? The second paddle cannot break the plane of the frame perimeter until 2 seconds after the first paddle returns. I doubt if your spinner is only going at 15 rpm.

The paddles never leave the frame perimeter. Even with the pneumatics extended. It just reaches just to the edge of the frame and doesn't ever leave it.

It was my mistake saying it ever went outside the frame because it doesn't ever go outside the frame perimeter

The current version of this beast has been toned down a bit from this, as it doesn't come into as much contact with the ball when the memory foam front is in use. However, it has been clocked with up to 15 feet of air!

If this is the case... and your paddles never go outside the frame perimeter please excuse my comments... they are not applicable within the frame perimeter...

Good luck
It looks like you guys will do really well!!
