Here in early 2018 we’re not far from robots being as prolific as PC’s. Here’s a great video of a robot that resembles a cheetah and can open doors.
Speaking of the cheetah design, robots are and will in the future be built on natural design, using as much of the real movements of the most incredible insects, mammals and birds in the world. Envisioning a robot that flies at night with the stealth of an eagle owl is nothing. Imagine the marvels we will build.
