Hmm.... well, I was hoping you'd be willing to go into a good explanation for the rest of the group, but hey, here goes.
Give this site a shot:

They have a plugin called TrueGrit that is FREE and is also aparently pretty good. I haven't played with it much, as it's rather late. But take a look, there is an HTML file in there that may be a bit hard for some to follow, so a good explanation, perhaps even with robot parts, is probably due. Tomorrow (WED) happens to be my off day, and I'm going to make it my tutorial day. Just write up a tutorial or two to share here each week. So look for a better explanation on TrueGrit tomorrow. Involving robot parts of course...
Good luck all, and happy animating.
