Minifigure robot legs

[Sailing bug]

Hi,

I really want some good robot leg for a Minifigure but the only ones i can find are Darth maul's robotic legs, are there any other legs out there or a way to build some good ones yourself?

You could use his hip piece with brick built ones ,Rodney Rathbone has more standard robot legs.
Grey minifig legs could work, some even have robotic prints.
