While military robots are ubiquitous in science fiction films, the ones we've developed so far are a bit more tame. Even still, ethical questions arise.

“The types of robotics we’re looking at are things we have already developed, but need to be modified to the individual and adapted to the particular function,” explained Leonessa.

Researchers have developed self-healing, biodegradable, 3D-printed materials that could be used in the development of realistic artificial hands and other soft robotics applications.
