Face-Tracking Robot

A robot is being developed that tracks facial movements to perform human tasks. The robot resembles large, squiggly arms holding tiny cameras. Sitting in a rolling office chair across from one of the arms, the robot's developer, Nathan Huber, demonstrates how it works. Huber rolls from left to write, forward and back, and the robot's camera follows his movements. He programmed the robot to track objects in planes. First, it identifies the object and locates it on the X and Y axes. Then, with a spatial-tracking algorithm, the robot can determine how near or far an object is in order to grab it.
