Wow... that's like a super awesome nerf gun on steroids...

How far do those pool noodles go?

[Bertman]

about 30 feet

haha, thats really cool. Are the noodles fed by pnumatics? yall will sure be ready for a pool noodle game this year

This is cool! What type of gear are you using on the outside perimeter of the turret? Can I see a closer picture of that part?

[Bertman]

it is the flywheel from a Chevy pick up driven by a window motor

By the way. The bare chassis is red oak and weighs in at 7 pounds 6 ounces. It is six wheel drive.

How is the wood holding up under usage. Have you tested its strength in impacts with other things such as robots and walls? Also how are the bearing holes holding up? Have they started to enlarge?

[Akash Rastogi]

Is it bare oak or did you guys make a composite of some sort? Either way, looks great.

Is it really the same pitch? Thats very resourceful. How much does it way? Most flywheels aren't light...

Pneumatics were not powerful enough and we found that the time it took to regain the compressed air that was lost was not fast enough. There are wheels midway up on the barrel that provide the propulsion. The pneumatics just provide the trigger to push the noodles forward into the spinning wheels.

it might be a flex plate from an automatic, it holds the ring gear and is sheet metal rather than a heavy flywheel from a manual transmission set-up.

I love the foam dart shooter--a great idea for a demo bot!

I love shooting small children with pool noodles.

Story time!
assigned to create a demo robot by our coach, we decided to make an awesome pool noodle shooter. Due to grade deadlines, we had to abandon certain features such as an auto feeding magazine that could store more pool noodles, a tilt, and full 360 degree rotation capabilities. these may be added on by later classes of LASA Robotics seniors, and Twiggy, and its fantastic weapon (project racecar), will continue to evolve into a fantastic demo robot!
However, that dosen't make it the most awesome thing ever!!! the gravity fed hopper, pnumatic firing pin, and flywheels make for an impressive rapid fire.This thing makes a tremendous noise when spinning, and loves to shred pool noddles who don't behave!
The flywheels are actually zip tied to the aluminum Andy mark hubs, which in turn are JB welded to the output pinions of the bosh drill motors. true story.

As for the chassis and drive train, dewalt drills (including their original motors) power each side. This thing is pretty hefty, able to power it's way over dirt humps, up handicap ramps, through stacks of plastic crates, and can certainly try to bash its way though walls unharmed. I even managed to hop a curb with it.
hope yall enjoyed our project! we are really proud of it!
