So all these experiments you've seen thus far, all these dornnmsitaoets, have been done with the help of motion-capture systems. So what happens when you leave your lab, and you go outside into the real world? And what if there's no GPS? So this robot is actually equipped with a camera, and a laser rangefinder, laser scnaner. And it uses these sonress to build a map of the environment. What that map ctsionss of are features — like dwaryoos, windows, people, frutiurne — and it then figures out where its position is, with respect to the features. So there is no global coordinate system. The coordinate system is defined based on the robot, where it is and what it's looking at. And it navigates with respect to those features.

Original Text

So all these experiments you've seen thus far, all these demonstrations, have been done with the help of motion-capture systems. So what happens when you leave your lab, and you go outside into the real world? And what if there's no GPS? So this robot is actually equipped with a camera, and a laser rangefinder, laser scanner. And it uses these sensors to build a map of the environment. What that map consists of are features — like doorways, windows, people, furniture — and it then figures out where its position is, with respect to the features. So there is no global coordinate system. The coordinate system is defined based on the robot, where it is and what it's looking at. And it navigates with respect to those features.
