Pusher Motor help required

Bonjour peeps

I'm trying to create something but i need help with moving a dart into a flywheel set up
other than taking apart a rapidstrike and using the pusher system from that,
could anyone point me in the right direction, probably need about 2 to 2.5 inches of travel for the set up i am thinking of and doesnt have to be auto, so even a simple design like that of a stockade, just with more length of movement (i have a stockade that I've cut most of and its no good)


thanks in advance

Miniature servos are popular, as are gear motors. Active Robots has a number of 50:1 gear motors with brass gears that might do the job, use a sector gear and rack to push the dart.
The servos need a controller of some sort, not looked at them seriously myself, but other people have. None of these solutions is as simple as using a RS set up.

Attach an appropriately shaped piece of plastic to an arm on a servo. With a micro servo you can get something like 2 cycles per second for travel distance about that long when pushing regular elite darts.
You'll probably want a controller of some sort. Arduinos are very beginner-friendly. In the case of servos they're also really simple to use (connect the servo, load up an already prepped library and tell it to go to town.)
If you aren't afraid of messing around with electronics then that's -relatively- simple. It's also essentially the exact kind of task servos exist to fulfill.

You could also try doing something similar to the Rapidstrike's pusher. Attach a disc to a regular motor, attach an arm to a point on the disc in a way that that leaves it free to wave back and forth a little and then attach that arm to a pusher arm that's attached to a rail so it can only slide back and forth.


... This would definitely be easier to describe with drawings.
The servo solution is probably the most likely to actually work. But I'm pretty sure they both should work at least in concept.

And yeah, ripping out a rapidstrike is definitely going to be easier than both of those options.
I'm not sure if it's actually possible to make the RS pusher any smaller than it already is. It -might- be possible though.
