Fully-Automated Nerf Stephan Cutter (FANSC)

Using Lego NXT i made a machine that cuts FBR into similar lengths
About 1.3-1.5inches
This is in the prototype stage
The programming was simple

- motor A,B sipn and slide fbr forward
-motor C cuts it
the only problem is that the blanks are not cut prefectaly flat (10degrees)
<p>Nobody's Prefect</p>
what did you use to cut it? a razor blade or scissors?<br />
what is cutting the fbr and can u make an ldd for it??<br />
cool could u post a how-to for it
why was the vid so dark?
There was light but the camera didn't "see it" very well.
yea i understand i took some pics at 12 noon and they where all dark
You could even do that on two motors. Nicely done. But it would be cheaper if it werent made of legos. But not everyone can program little circuit thingys. ( i wish i could =( )<br/>Add a light senser to make it stop when it runs out .<br/>
Well this is certaintly FANSCY Hehe
how mush dus this cost?
a LEGO NXT set cost 150$ if you want to get one i didn't buy any extra parts, i only used 3 motors
I don't know why i'm saying this but my older brother's name is Stephan
hey you shold put up the instructions for this
instering i wish i had the nxt
weah. if this could also attach the washers and make a straighter cut, you could sell something like this
i know only problem is that if you want a custom machine that would do that it would cost about 10 to 20 thousand dollars
true, thus making a cheap machine like this much more marketable
For the uninitiated, what is it cutting and what are the bits used for?
It's called foam backer rod, which is normally used to fill gaps in trim or cracks in asphalt, prior to sealing with caulking. In this case, FBR happens to be the perfect diameter to use as ammo in home-made nerf guns - just cut it to length and add a weight to the end.
