Cool! Is that an electrostatic Nerf rail gun?

I don't get it... How does the ball get accelerated?

Re: pic: 108 Gun Teaser

Belts (that aren't shown) line the sides of the gun, two pulleys aren't shown either. The belts will spin ridiculously fast and out will come a ball at (hopefully) 12 m/s in a relatively straight line. We hope....

108

P.S. the estimated acceleration of the ball is 283 ish m/s^2.
time spent in barrel = .064 seconds.
at that rate, it should take only 293 hours, 46 minutes, and 41.17 seconds to reach the speed of light.

Don't forget about air resistance with your light speed calculation there, it would probably take more like 500 hours.

Don't forget physics/realitivity. It's impossible.

but most importantly dont forget the 12m/s rule.

Looks great. Nice design.
Is it legal to transport balls from the robot to the center goal
How would they measure the m/s?
If a ball disappears from the bot and reappears at the goal than there is no velocity. Right?

Figures. While we are all designing shooters, 108 is making a futuristic scifi levitation ray to put balls in the center goal directly from the ground.
