Interactive social robots to participate in AAAI’s Annual Mobile Robot Challenge


Grace and George, a pair of socially skilled robots developed by a team of researchers from Carnegie Mellon University, the Naval Research Laboratory and Swarthmore College, will participate in the American Association for Artificial Intelligence (AAAI) annual Mobile Robot Competition and Exhibition July 27-29, at the San Jose Convention Center in San Jose, Calif.

Grace and George are six-foot-tall, socially adept, autonomous talking robots with digitally animated faces. The robots will work as a team to complete AAAI’s Open Interaction Task, which involves interacting with conference attendees in an unstructured environment.

Grace will "work" at a booth, communicating information about the conference and schedule, while George circulates among the crowd, interacting with people, answering their questions and escorting them to conference locations. Grace will contact George and schedule times for "him" to meet and escort people to various locations. Those being escorted will put on a specially colored hat, and George will lead them to their destinations.

Though the robots have participated in AAAI’s challenge since 2002, their role in this year’s conference poses a new challenge.

"Having George and Grace operating throughout the conference ? not just for an hour, but working throughout the duration ? is more of a challenge," said project coordinator Reid Simmons, research professor in Carnegie Mellon’s Robotics Institute. "We’re pushing for a sustained presence by the robots so people can interact with them at their leisure."

He added that the group chose to participate in Open Interaction Task instead of the Robot challenge because they wanted to showcase the human-robot interaction focus of the Grace and George project.

Grace competed in AAAI’s Robot Challenge in 2002 where she acted as a conference attendee. She managed to find her way to the registration booth at the Edmonton Convention Center, Alberta, Canada, register for the conference, navigate to an elevator, and find the third-floor conference room where she gave a PowerPoint presentation about herself.

At future conferences, Simmons says the team will continue to focus on human-robot interaction, with hopes of developing reliable speech recognition and creating robots that would fill the role of volunteer workers at the conference.

Im Focus: Novel light sources made of 2D materials

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
