could you possibly design a suspension that could keep a chain tensioned? Possible have it move around a point that would have the chain stay tensioned as it goes up and down?

Or could you have a chain tensioner that keeps a chain tensioned by use of springs and have the springs that hold the chain tensioned be easier to compress/expand than the spring or whatever you are using to make the wheels have suspension.

I am trying to design a suspension for our robot next year but the wheels would be powered in one way or another I don't see a point in having a suspension if you are not going to power the wheels. What is the reason behind having a suspension on unpowered wheels?
