Today on In Case You Missed It: Stanford is teaching drones how to avoid either existing obstacles or ones that come in the form of an attacking human. It all works in real-time, which is why the video of the technology in action shows a fencer sparring with the drone. German students have created a wheel that works like a robotic bicycle chain, morphing its shape from round to triangular -- whatever is needed to get over obstacles in its path.
