Subject: efficient launcher?
aiming is also an issue and when to fire. its a bit ackward to show your
friend your new bot and it shots him in the eye. and getting the hook off .
this idea would take loger and it would be harder but worth it. you could
have to motors turning outward then the hook gets shot out. the hook woould
have to be spring loaded so the hooks move out farther for better grip then
when it is
pulled back in the hook at the bttom iscurved inward so it fits nicely for
a second launch.
