Anticipatory robot holding open a fridge door
What’s better than as robot bartender that can pour you a beer? How about a robot waiter that can see you need a refill and comes over to pour you another one.
Hema S. Koppula, a Cornell graduate student in computer science, and Ashutosh Saxena, an assistant professor of computer science are working at Cornell’s Personal Robotics Lab on just such a robot. Using a PR-2 robot, they’ve programmed it to not only carry out everyday tasks, but to anticipate human behavior and adjust its actions.
Robots are the neat freaks of the technology world. They like things to be tidy, orderly and predictable, meaning they work best in places like laboratories and factories where everything can be controlled and where it’s easy to predict what’s going to happen next. When a robot moves out of its comfort zone into our imperfect world, it can run into difficulties. Even something as seemingly simple as noticing that someone’s glass is empty and topping it up requires a lot of observation and planning on the robot’s part.
The Cornell anticipatory robot avoids embarrassing spills and other accidents by using its Microsoft Kinect scanner to build up a 3D map of the objects present and then calculating how they might be used based on the action currently being performed by the person…
The robot is also able to put various subactivities together in different combinations to form models of larger activities that it can use to anticipate the movements of people in different situations. The models it builds are general enough to take into account the fact that different people will perform the same activity slightly differently.
