2 months ago I saw this video for a knex crank shaft. the motor was not strong enough to launch the white rod. so I had a idea to use the motor to pull back the ram. this is what i came up with. its not very powerful but is a machine gun with no chain.
this is my first Instructable so be nice.
the instructions are done
please post any mods for a different motor.
update the gunbot 2.0 instructions are hear!!!! ya!!!
because not every body liked the mg and and i have many other things i could put on it the body is know going to be known as the bot and the mods determent the name so the first bot is gunbot.
mod can be posted on this forum http://www.instructables.com/forum/TL8ZZKSF7KZRMSD/
instructions for knife bot 2.0 hammerbot 1.0 and 2.0 drillbot 1.0 and pushbot 1.0 (working on name)are not going to happen!!!!
not many people commented that they made it or that they cared about these bots being made. i have moved on to a rubber band shooting robot that can fire 6 rubber bands at a time. i will post the instructions for the mod for the bot to make it fire rubber bands. the robot will have its own insructable. it will be able to turn, have hands that will move, and have two of my automatic rubber band shooters. it will be done with cyber knex motors(if i can find them on ebay but i haven't had much luck). all that comes to 8 motors. i hope it will work.
it worked... kind of. i did not use the cyber knex motors. i used the control-a-bot motor that i had laying around.
it is here. http://www.instructables.com/id/knex-robot!!!!!!!/

Here's my arsenal:
Your arsenal looks good, just that little pistol(KillerK's?).
I forgot to mention that I have two of the 18 barrel things made...
The little block trigger pistol is actually Mepain's shotgun mod to Killerk's pistol, it shoots 4 yellow rods in one trigger pull. It gets good ranges, around 40-45 feet. The block trigger is very comfortable and easy to use. Here's a link to a video: www.youtube.com/watch
Lol, the BR is 8 barrels, not 18.
i estimate that each pieces is around .25$(some more some less but .25s a good guess). i have a estimated 13000 knex so 13,000 * .25 = 2,833.33$!
