Bionic Hands have revolutionized the lives of the amputees.
Historically, leading prosthetics can cost up to 100,000 USD (according to the Open Hand Project). But, with the advancement of 3D printing, this cost can be reduced significantly!
Lower cost means larger market reach and increased impact!
" The prosthetic system shall allow a soldier requiring a prosthetic arm to eat a McDonald's Quarter Pounder with Cheese meal. The prosthetic system will be designed to support the large community of wounded soldiers needing a prosthetic arm. While a fixture may be used to hold the meal, the other arm may not be used to feed the hungry soldier. "
It is not uncommon for soldiers to return home missing a member.
Use of prosthetic limbs help allow these men and women to retain relatively normal functioning.

Use of EMG (electromyographic) signals may be costly and complicated - EMG input can be as small as .5 mV - Noise can be an issue.
Use of EEG (electroencephalographic) signals may be difficult to acquire
Force applied at the output must be very precise to the object that it is interacting with
Everything must be compatible with the adjacent arm, being built by others
