[Yaaarc] Robot toy armament

[Robert]

Seems like the pellets could be slowed down a bit... just reduce the size of
the spring on the mechanism.  The plastic pellets are very low mass, an
order of magnitude less energy imparted then a paintball gun, but probably
still not safe enough to avoid a lengthy court hearing given an out of
control robot.

When I was a kid I mounted a squirt gun nozzle to a washer fluid pump on an
RC car with a mini trailer full of water.  That qualifies as cute and fun,
but not indoors or electronics friendly.  Target has a Speed Shark Motorized
Water Gun ($15) that would get the job done.

Wow.

Fully electric and automatic, 16 to 1000 round magazines, under $20.  Wow.
Just hack the simple switch and go, that's the best part of all.

Are those plastic pellets at 150FPS just a bit dangerous?

I was thinking about mounting some kind of turret on a toy car, about 
16" long.  I guess I could just use a laser pointer for now.

Or maybe I should be building on my Barbie Jeep bot chassis, it's 
proven technology, it could fit a bigger Airsoft gun easily, and it 
would be damn impressive.  Almost too impressive maybe, I was aiming 
for "cute or funny" not "scary".  If a Jeepbot with a rapid-fire 
150FPS pellet gun got out of control, I'm not sure anybody would 
really want to rush in and hit the e-stop.  Not without a face shield
anyway!

But if it's the size of your cat, and it chases you shooting foam 
nerf darts or mini-marshmallows, it would be just funny.
