This reminds me of the big stink Harvey Comics made about the ghost in the "Ghostbusters" logo, when lawyers for the company were claiming that the logo ghost ripped off one of Casper's uncles. Or when the Kellogg's people were griping about Exxon's tiger looking like Tony.
As for robot forms, they run the gamut from Tick-Tock the mechanial man in the Oz books to R2-D2 to Marvin the Paranoid Android to ROG-2000 to the Daleks to Data to Kryten to Twiki to ED-209 to Rosie...
Coincidence or not, I think Bender looks like he does for the animators' sake. Giving him the ol' "rubber hose" look for his arms and legs helps speed things up in the animation process, I'm sure.
