The director of that awesome James Bond quadrotor video from last year has unearthered some fascinating footage from University of Pennsylvania professors, detailing robotic breakthroughs that lead to the creation of the acrobatic RHex, self-assembling modular CKbot and the aforementioned flying marvel. According to the director, the short video was compiled using largely unseen footage that dates back to the early 80s. Well worth four and half minutes of your time.
