As weird as it sounds, but carbon fiber is the most accessible material for making a DIY robot. Anything that uses metal requires expensive machinery. Carbon fiber is labor intensive (i.e. bad for mass manufacturing), but doesn't need much equipment beyond a curing oven for the epoxy (around $2000) for state of the art results.
