"Helix" robots in 2006/2009
Does anyone have any videos/pictures (videos are preferred) of robots from 2006/2009 that use a "helix" to get the balls up from the floor to the shooting mechanism?
Thanks! PS: I already searched, both CD and Google. |

1717 and 1771, 217, and 148 may be places to look. Though tornado was spinning the balls downward instead of up.
Edit: These are for 2009 |

Also in 2006 I believe that 469 had a helix for moving/storing the poof balls.

Remember only three balls max may be carried by a robot, and any more will get you a 3 point penalty each. Don't count on any complicated hopper or container being useful.

Thanks for the robots, but aside from some robot videos, I can't find anything that clearly displays the helixes and how they work. Pics/videos are appreciated.
*And for all of those who will complain, YES I have searched this already. |

Here is a video showing shooting and helix. I agree that the helix may not be the best design for this years game, but I don't want to limit your thinking.

There are many examples from 2006 in the Aim High:Behind the Design book. I have a copy, and will upload some of the pictures later tonight if I have time.

461 Did a helix in 2009. Feel free to browse the photos and information on our website.
Hope this helps, -Duke |

To answer your question of how they worked. You would have a center axis that would rotate 360 degrees. Attached to the center axis would either be fingers or brushes to move the balls towards the top. The spiral would raise in a clockwise fashion and the brushes/fingers would spin in the same direction. Here are some other Archimedes screws from 2006/2009 1100-2009 233-2006 1771-2009 I agree with Martin. I don't think a screw is completely necessary as you can only possess 3 balls at a time. |

Here's a video of the prototype test of ours, you should be able to find more videos from the same channel around the next few weeks after this was posted, that show it working in the final robot. Or maybe not, I don't remember.

Check out the Robowranglers (#148) from 2009 on FRC Designs. Look at the picture, video, and CAD for ideas!

Not sure how long that link will stay up, we're creating a new website. About a helix, its really not necessary to hold anywhere near the ~25 balls our robot could that year since you can only have three. |

One simple solution a few teams used in 2009 was to use flexible plumbing pipe for their archimedes screw to get the helix they needed without all the parts. http://www.chiefdelphi.com/forums/sh...ight=pic.+1100 |
