Kinetic Energy Flipper

[typhoon_driver]

Not even close.

You can see from the pictures. The ring is spun up by the motor which engages with the teeth in the ring to transfer power. The ring has an off center circle machined into it. The flipper mechanism engages in the off center circle and transfers all the energy into the flipper.

Rather then all this fancy machining with custom clutches could you use a mountain bike brake disc and calipers to transfer the energy?

[typhoon_driver]

Doubtful as you wouldn't get a sudden impulsive transfer of energy which you need for a flipper

[Daniel]

I don't know. I've gone arse over tit a few times on a bike from hitting the brakes too hard. Mabye gearing the the rpm's down between the fly wheel and clutch would be smart since you don't need a flipper spinning at 10000 rpm

[typhoon_driver]

Yes but you have a large radial momentum based on where your body is in relation to the brakes. Feel free to try but I can't see it working

I've thought about the bike break thing before too.

I'm pretty sure the amount of force you can apply with your hand on the brake lever is going to exceed any Servo.

I would have a go. :shock:
Do a mock up and test how practical it would be, the more variations on weapons the better.
In competitions I think you should get points for being different

[typhoon_driver]

You would have to use a linear actuator or a small pneumatic cylinder to give you enough force. Either that or use hydraulic brakes. Of course, the issue then becomes transferring the energy from one moving object to another. A heck of a lot of design required.

I think you miss the point of the servo PJ-

Im pretty sure the servo only moves a linkage to engage a clutch... i.e. moves a lever which gets put into the spinning disc to lock it solid, the force then gets translated into the flipper....

Kind of the like the principal of ramming a metal bar through the spokes of a bike wheel while someone is on it...when the bar locks against the front forks of the bike, the energy is put into throwing the unlucky person of there bike....

I'm saying making the caliper grip with enough power would be unlikely with a servo.
Yeh you could use a pneumatic cylinder, but doesn't that kind of defeat the object? Just use that to power the flipper.
