Size variation, maybe? If you're building an industrial robot you control the size precisely, but if you've got to make everything variable - and not just variable, but to be as comfortable as clothes - I can see that throwing a hell of a lot of complexity into the mix.

I mean in theory the motors and controllers are identical across all builds, but since the length of the rotating pieces is variable, the angles of rotation might remain the same but the leverage and hence the torque vary by quite a bit. Bigger people have longer limbs, and bigger people also weigh more.
