Reference Pictures for Robot Design

I apologize for not posting anything on Thursday. I was in a competition to get into Skills USA. Anyways, today the class had to come up with concepts for a robot that I assume we will be making in Maya soon, so I got some reference images and I am currently sketching out ideas for the robot. I don't have any sketches at the moment, but I have the reference pictures below.

I feel like I left out a few pictures, so here is the link in case you want to take a look for yourself http://www.pinterest.com/chaosdragon115/pics-for-robot-design/
