Why don't robots have toes?

[plooby]

I've seen all these robots like Asimo, which sort of squat because they can't balance properly with their legs straight. The reason? These robots have no toes or heals! No wonder they keep falling over!

Try leaning forward you will see you straighten yourself up by pushing with your toes or lifting your heal forward to reposition your weight.

Have you ever seen a robot with toes?

  Hello!
 I have only seen toes on the terminator robots, but they were fiction.
In the real world, I have not seen any robots with toes that resemble
human toes.
I have seen alot of experimental walking robots on Youtube that did a fine
job of walking without toes, but the server that controlled them was not far
away.
I imagine, in the future, a real autonomous huminoid robot may be very different
from what we expect now. Power usage, physical work load, and academic work load
will dictate the design, I expect.
Interesting question, never really thought of that before....

The short answer... they would add complexity and more degrees of freedom. Walking robots are already very complex mechanically and its chalenging enough to decide how to move all the joints that are there.

That doesn't mean this isnt a totally valid question but I have not studied biomechanics to enough to understand the exact benefits and if they can be accomplished with simpler means. Have you looked for any research in this area, perhaps applied to prosthesis?
