If you could walk into your local hobby shop and buy an empty robot shell to build and customize who would you bring home, R2, B9 (Lost in Space), K9 (Dr. WHO) etc?
One that I think it's cool: Johnny 5.
I will go with eva from the wall-e movie .Although I like the vintage touch wall-e has .
B9 from the old Lost in Space Series will always be the robot I think of when I think of ROBOT. I loved every part of it and wanted one desperately as a kid. Robbie the Robot rates pretty high too.
...lets not take anything away from Frits and both his SHR's....
