robot learns to clean whiteboard

Some people hate cleaning whiteboards, and that's where HOAP-2 comes in handy. However this robot doesn't actually know how to clean, but it can memorize the pattern in which to move its robotic arms. To do that a human has to come up to the robot, moves its arms to the pattern of the cleaning method, and then the robot plays the movements back like a simple program. Check it out in the video.
