Catapult?

[Tim Arnold]

Check our catapult-like device out in prototype: http://marsbot.org/files/arm_demo.zip

We finally got our hardened shaft and everything is coming together now. I will try to post a video of it throwing tommorow (assuming it can do that yet )...

The good thing about this was that our robot did not shoot at different velocities because of the change in our battery level.

Boy was that impressive!! I remember that one.

Our shooter was just rapid fired for the first time yesterday and I am proud to present a video of our bot firing. Please let us know what you think (leave a comment here)!
