Ladies and gentlemen, say hello to PIBOT. Developed in South Korea, this little machine is about the size of a child’s toy, and has a head that kind of looks like a toaster (烤箱). It’s also able to fly a plane.
The researchers responsible for the robot’s development have actually managed to program it with all the knowledge and skills necessary to operate a standard airplane. Through a built-in webcam (网络摄像机), PIBOT is able to gather information about its surroundings — such as location, airspeed, and weather conditions.
With all of this information, it’s able to make decisions in much the same way as a human pilot would. It’s already completed one successful test flight — sort of. In the video presented at IROS 2014 in Chicago, PIBOT was seen guiding the airplane through a short test flight in a flight simulator (模拟器) — a process which included both takeoff and landing.
It’s super cool.
Now, it’s worth mentioning that — even as impressive as PIBOT is — we aren’t going to be seeing it in any real airplanes at any point in the near future. Although the little robot is certainly able to operate a plane, it doesn’t quite have the skills necessary to address some of the real world situations met by pilots — such as bad weather or mix-ups on the runway. It doesn’t meet the government’s rules, either.
The inventors aren’t terribly discouraged, however. They expect that it’s only a matter of time before they manage to get PIBOT up to the necessary standards. When the day comes, we might see airlines put to work a whole new type of pilot; one who never tires, never gets hungry, and never makes mistakes.
So ... if you’ve a career in aviation (航空), it might soon be time to start planning for retirement (退休).
