Wow. I have been waiting for these pics for a while now :D

That is pretty innovative (but simple).

I like it.

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!".

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.

Re: pic: 1625's shooter ready to fire
 

its got an ma3 absolute analog encoder on the other end of the shaft of the big sprocket to tell it where its at.

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?

Re: pic: 1625's shooter ready to fire
 

Pretty winnovative:)

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?

Re: pic: 1625's shooter ready to fire
 

the FP motor that steers the wheels, it actually helps for when the bots running for more than 2 minutes.

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.

We wanted to accomplish a punching mechanism without having any other actuation, as we've never used pneumatics once in our 4 years and another motor is more weight.

Re: pic: 1625's shooter ready to fire
 

Are there any safety features on it?

Re: pic: 1625's shooter ready to fire
 

it doesn't move if we don't tell it to, by leaving the anti-backdrive pins in the dewalt. And if it dry fires nothing goes flying. It only is able to shoot when in the correct firing position. besides that we just used our "don't be stupid" policy and it hasn't gotten anywhere near to harming anything

Re: pic: 1625's shooter ready to fire
 

So if I were to bump the wheel when it is loaded it wouldn't shoot?
You use a crab drive right?
