Re: Catapult?

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 :rolleyes: )...

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)!
