Military aims for better limb replacements

From the article:

A new research agenda set out by the Defense Advanced Research Projects Agency (DARPA) aims to restore some of the lost functionality for these soldiers by developing advanced prosthetics that look, feel, and act like the limbs they replace.

The ultimate goal would is limbs that would work well enough to play piano and live normal daily lives.

The keys to better limbs are precise neural control, lots of small but strong motors and a small power source that can hold up all day. That will be a challenge given the amount of space available in a forearm, for example.
