I love Legos (ok, LEGO, whatever), but this seems like it deserves 3d printing. It's an ideal application of 3d printing, since many parts need to adapt sizewise, so injection molding doesn't make sense. Modularity is neat, but doesn't lend itself to practical designs that are strong and space efficient. My hope is that prosthesis tech and robot tech converge. If we can make really good artificial limbs, cheaply, we can not only help people who are missing natural limbs, but we can, ya know, train them to fold laundry or assemble iPhones. The field will take off in a big way when someone designs an arm that can play a large role in fabricating and assembling an arm like it.
