Wow. I have been waiting for these pics for a while now :D
That is pretty innovative (but simple). I like it. -Vivek |

1625 is awesome. Everyone on 1251's scouting would like rave about you guys in Newton. I'm glad we got to play with instead of against you guys in Elims. Great robot this year, innovative,proven, and effective. Good luck at IRI to Aren and the rest of the 1625 crew.

Congratulations to the gang at 1625 on coming up with such a simple and elegant solution. Pretty much everyone from 1114 had the same reaction when we checked out your shooting mechanism in Chicago, "That's so cool!".

Re: pic: 1625's shooter ready to fire
I like how the shooter has the words "Sucker Punch" on it.
Nice work 1625 on another fantastic robot. |
Re: pic: 1625's shooter ready to fire
Took me a while to figure out how it worked, glad you posted the second picture of it as well.:)
Very simple, yet effective design. :D |
Re: pic: 1625's shooter ready to fire
wow great design! took me a second to figure it out. never would have thought of that... I assume you have a pot or other sensor so you dont miss fire.

this mechanism never gave us a problem during the whole season, very easy to maintain (also i came up with this linkage concept 4 years ago playing with legos....) |

What is that giant heatsink on?

Seriously though, that is one pretty awsome shooter. |
Re: pic: 1625's shooter ready to fire
err..... how does it work?
I'm guessing the arm has freedom to move inside the half-circle? -Leav |

Leav, look at the next picture of our shooter and you'll get a better idea how it works, its kinda tough to do with words. Quote:

Re: pic: 1625's shooter ready to fire
Are there any safety features on it?

Re: pic: 1625's shooter ready to fire
okay, heres how this thing works. In this picture the shooter is currently ready to fire.
there are two linkages, one hinged to the puncher itself and one hinged to the large sprocket, then connected together. Currently the forward force of the surgical tubing is holding the linkage quite tightly against a catch on the face of the sprocket. In order to fire the large sprocket rotates, moving the hinge point of the rear linkage over center and therefore there is no catch to stop the puncher from flying forward, hence it flies forward. this leaves the shooter in "unloaded position but both linkages fully outstretched. The large sprocket then rotates the same direction it did to fire, drawing back the rear hinge point hence partially loading the shooter. Then once the hinge point 180deg from where it was the catch grabs the linkage and it does another 170deg rotation, to be back ready to fire. i hope thats not to confusing, i managed to explain it to people in person but alot of talking with the hands was involved :rolleyes: |
Re: pic: 1625's shooter ready to fire
That shooter is very impressive. I watched you guys in some of your matches and I extremely impressed. I know this thread is about your shooter, but your drive train is incredibly cool as well. Do you have any pictures or CAD models that you can post of the drive train?

Re: pic: 1625's shooter ready to fire
So, from where we are looking, the sprocket rotates counter-clockwise, the metal semi-circle that is attached to the sprocket hooks the bolt connecting the two bars and draws them back?
That's pretty neat. I like how this is all accomplished without pneumatics. |

The aluminum bolted to the sprocket is just to give the linkage a flat plane to slide on. |
Re: pic: 1625's shooter ready to fire
that is a wonderful design! I love Linkages:p :p Seems really simple too. Did you have any problem with the tubing?? Our team always had problems with it in our first year, so we never looked at it again haha! I suppose maybe we should... it helped make an amazing robot!

it was ziptied in place to whatever it went around. |
Re: pic: 1625's shooter ready to fire
problems as in ripping and stretching... I saw a whole bunch of people using it this year so I'm going to assume in 2005 we had a bad batch or... we were really bad at using it haha

Re: pic: 1625's shooter ready to fire
Yeah that thing was a beast to play along side of in colorado. Just wish we wondent have fried our computer.lol. Hope to play along side u guys agian someday.
