Another set of experiments showed the robot could learn to tell whether or not something was a container. After just one action the robot had a 72 percent success rate, but its accuracy soared with each successive action, reaching To figure out what an object is, HERB compares its live camera image with a set of 3-D models in its database, built up from representative images that researchers showed it earlier.
The robot could then use this knowledge to judge whether unfamiliar objects could hold things; in other words, it had learned, roughly, how to discern the unique characteristics of a container. It must be trainable. HERB also uses imitation learning to figure out how to handle objects by watching how people handle them.
By dropping a small block on each one and then pushing it, the robot learned to classify objects either as containers—those that moved together with the block ["co-moved"] more often when pushed—or as noncontainers.
First, HERB has randomized planning algorithms to determine the best way to grip or move something as quickly as possible. Then they realized this was a "far more efficient motion" used by professional bartenders, Srinivasa says: It used a strange hand position, with one of its "thumbs" pointing down.
But first, says Alexander Stoytchevan assistant professor of electrical and computer engineering at Iowa State University in Ames, robots have to be taught to do something we know instinctively: Srinivasa would eventually like HERB to learn some simple social rules—such as knowing to go around a group of people rather than through them—as well as how to deal with completely unfamiliar environments, even in the dark.
A useful robotic assistant is about a decade away, he estimates. The three-foot one-meter machine balances a Barrett WAM arm and a BarrettHand atop the base of a Segway personal transporter with two small training wheels.
For example, the robot might be given 30 seconds to "think" of a way to pick up a mug; if it finds one in 15, it then has 15 more seconds to improve its plan. In one set of experiments, the robot was presented with 36 different objects, including hockey pucks and Tupperware.
To find its way around dynamic environments, HERB uses two laser range finders and a camera that let it tell people apart from fixed and movable objects like walls and chairs. Manipulating objects in cluttered settings, like carrying a pitcher through a house without spilling anything, takes two skills.
Similarly, the days of "personal robots"—inexpensive machines that can help out at home or the office—may be closer than we think. The team presented the machine, topped with a 3-D camerawith objects of different shapes.
It could perform five different actions with each one—grasping, pushing, tapping, shaking and dropping—and had to identify and classify them based only on the sounds they made.May 14, · Watch others. Get out there and try to make friends.
