Catapult?

[Alan Anderson]

I think a well-constructed catapult is likely to be more consistent in its aim than a wheel-driven shooter. I also think it's pretty obvious that a catapult will be slower than a wheel-driven shooter.

Any teams designing a catapult will have to be careful not to run afoul of the very first rule.

...An example of an unsafe design is a shooter mechanism that has a large mass that is stopped abruptly at the end of travel and is at risk of breaking off the ROBOT and becoming a projectile.
