How to get the ball over the overpass!?

[flamefixed]

springs or momentum type *throwers* probably will have trouble getting past inspection because so much energy will be required, and it becomes very unsafe. Last year springs were used on our robot as a buoyant force so we could easily raise and lower our ramps, not in a way to rapidly release all that potential energy.

<R60> Items specifically PROHIBITED from use on the ROBOT include:
 Electric motors and/or servos different from, or in addition to, those in the Kit Of Parts, with
the exception of those specifically permitted by Rule <R59>.
 Electric solenoid actuators (note: electric solenoid actuators are NOT the same as pneumatic
solenoid valves – the latter are permitted, the former are not).

...why those firgelliautos actuators are definitely NOT allowed?
