Has anyone seen the newly released ASPIR 3d printed robot? It seems like a perfect robot to be controlled by EZB.

In the comments, the author explicitly states that he hasn't actually used it yet. And that he's unsure if the power will actually be enough - I'm leaning toward the latter - it won't be enough.
The head really needs some work. It's probably not the ugliest robot I've seen, but it's up there :D. The designer truly spent a lot of time making it, but maybe he/she could have spent another few hours making the parts look better. Everything is square and the rounded corners are all different angles. Some corners aren't rounded as well.
The head is the most challenging part for it to consider walking - not to count that the servos won't hold the weight and the bracket's mounts look super loose.
I'd make an inmoov way before I considered this thing
I fitted it with wheels and, to have a working walker, I downsized to about 2,2 feet . The servos I used for the legs (24,7 kg.cm) don't allow anything larger.
Now there are some monster servos (hitec 110kg.cm at 14,8 V) that could perhaps, with lipo batteries , handle the large robot.
But their cost is very high ( 434 $ each !).
One interesting idea I saw in the Aspir project is the use of RC shock absorbers used there in feet and arms linkages. It's a great idea to improve stability and smoothness of movements in a walking robot. What do you think about this ?
maybe this video can be of use for you.building big walking robot.
EZB makes experimentation easier.
big humanoid
And that way I'd have nothing to do.... Robobuilder has done the whole job !
I like doing it myself.
