Here some very simple demonstrations...
plus i can't really get a good angle on his head, it's oblong and the face has a weird angle save for the eye sockets (i put them back in the head a bit, so the openings are flat)
Without knowing the size or shape of your robot's face it is difficult to design something to fit into it. Here is what popped into my head though. If you can fit servos, or micro servos, in around his eyes, this might do the trick. You would need two servos for each eyelid. You would have to decide if you wanted to do all four, or just upper ones. Figure one shows how they could go together. The red servo would be stationary, attached to something in the head. The blue servo would be attached to the horn of the red servo. Of course the thin plastic eyelid would attach to that. Rotating the servos would give you the motions that you were looking for. I think the pictures are self explanatory.
Figure 7 shows that they could be put either between the eyes or on the outside. To fit them all in, you might put the upper lid servos on the outside and the lower ones between the eyes, or vice versa.
It is just an idea that you might want to play around with.
