Earlier today on Wonktalk, Sarah Kliff and I were discussing whether robots were going to take all our jobs, improve our health care system, or obliterate humanity. Apparently there was a fourth option we'd missed — and it's the most terrifying of all:

Engineers at Boston Dynamics, with funding from the Army Research Laboratory, have created a horrible prancing robot horse that can hurl heavy objects over large distances.

Here's their explanation: "The goal is to use the strength of the legs and torso to help power motions of the arm. This sort of dynamic, whole-body approach is routinely used by human athletes and animals, and will enhance the performance of advanced robots."
