Has anyone ever used project foam board as a building material? Im thinking of building a small robot using 3/8" foam board as the main structural material. I know that it can be glued together to create the chassis but what other ways other than glue can be used to mount the components to it?
By foam board i mean the stuff used in schools to mount your presentations on.

Often called "foam core".
And yes, people have built robots from it.

So what is a good mounting scheme on Foarmcore? I would rather not glue my expensive electronics to it.

Velco and double sided foam tape work great.

You can drill/punch a hole in foam core for mounting. Use wide washers (fender washers) on either side of the foam core. The wide washers will compress against an larger area of the foam core than just a bolt head and nut.
It certainly depends a lot on the size and type of robot, but I have seen a flat robot base made of a double layer of foam core. Motors were mounted using wide washers. The robot was made with foam core, rather than plastic and metal and gained rigidity with foam core cross sections. It was a light robot. Assembly was done with hot glue and tape.

Alright, sounds easy enough. Thanks.

Not quite, as its sandwiched between cardboard.
Another option: fold and staple parts together.
