NASA and GM's Robonaut2 allows human astronauts to feel the fear of obsolescence (video)

About a decade ago, two of our favorite government entities, NASA and DARPA, paired off to create the robotic astronaut of the future: Robonaut. He had a cool copper helmet and some faux-muscly arms, but ultimately never made it to space. Now, 10 years on, NASA's back with Robonaut2, created along with General Motors, who hopes to enslave poor R2 in its assembly plants. The details of exactly what has changed in this iteration are slim, but R2 is said to be more dexterous than its predecessor and stronger too, able to lift a 20lb dumbbell without getting all red in the face. It also seems to have lasers in its knuckles for some reason we can't quite figure out, but we're digging the look nevertheless. R2 is said to be helping NASA into a "bold new era of space exploration," and while we don't know exactly when that bold new era begins (now?), we do have a particularly menacing video of the original Robonaut included below, as well as one two of the fit and trim new model.
