I realize this isn't a robot, but I found it just too cool not to post:
I knew this was coming
I hope these aerocars will be available commercially soon (at least in kit form)
My only regret is that I don’t have the money to build one myself. My friends any I were discussing a human sized multicopter a few months ago. I would have gone for more propellers, but that was just intuition, we never sat down to do the math
