Where's that robot?

You know, I could have sworn I put this up here in an earlier post, but I can't seem to find it. So I may as well do so now. This image is entitled "Where's Wall-E?" and you have to find the famed titular Pixar robot. But that's really only secondary (and he's not that hard to find). The real fun with the picture is identifying how many other famed movie and TV robots you can name. Two of them are from Oz, of course, else I wouldn't be posting it here. (Okay, technically, one isn't a robot, but that doesn't stop a lot of people from thinking that this character is a robot.) Once you've pored over it, the answers are right here.
