The picture of a rather odd robot is from Ain't It Cool News. The pic is reported to have been taken from the Chicago set for Transformers 3 with the robot being called "Bruiser". No other context was provided. If this is for Transformers 3, then the name is likely a placeholder name and of course CGI will likely add some life to the prop.
For reasons I can't nail down, that robot makes me think "Frankenstein's monster". This in turns makes me think that maybe a plot element is an attempt by humans to re-create Transformer technology but that is just speculation on my part.
Update: It appears "Bruiser" is for Hugh Jackman's next film "Real Steel" which has been filming in Chicago. The movie is coming on November 18th, 2011 and "tells the story of a father and his estranged 11-year-old son who enter the world of robotic boxing. You see, in the future, human boxing has been outlawed, replaced with sports combat between human-trained 2000-pound heavy steel robots." The little bit of robot that shows does indicate a simliar design. Thanks to Katie for the info and link.
