A Real Flipper

I also thought about clutch-type mechanisms a long while ago. Dismissed it as it's far too difficult for me to build with hand tools on the kitchen table!

Wouldn't it just be easier to build a vertical spinner???

This is a very clever solution, made by jyhu, a roboteer in Finland.

I dont see anything that says "spinnerproof" on it

Why dont you try something like team whyachi's Red Square. I remembered reading about it in Real Robots magazine. Where its flipper was just a heat treated titanium strip that was attached via a kevlar strap to a 20,000:1 (yes i know

) winch powered by an astro motor. to release it they basicaly made one of the free rotating gears slide along the axleso the winch pulley was free spinning.

Im thinking of re-creating the same aspect in an antweight with a sanyo NA series gear motor geared at 175:1 which has a stall torque of about 2000g and a TITCH 44 servo (4.4g) to release the gear as it doesn't have much friction if all my corrections are correct.

I thought about that sort of technique a long time ago, but it's pretty complicated on a small scale - and bulky and heavy too.

I think the release mechanism would be tough to get right. The forces on the gears that you are trying to disengage will be very significant. Still, it might be possible...
