The robots’ creators and others close to them accepted a certificate in their honor. Jacob R. Matijevic of NASA’s Jet Propulsion Laboratory accepted for the Sojourner rover. Matijevic was responsible for the implementation, integration, delivery and eventual operation of Sojourner on Mars. Joseph F. Engelberger, described as “the father of robotics,” whose company Unimation installed the first robots on a General Motors assembly line in 1961, accepted for Unimate.

Kathleen Holliday, director of special programs at Lucasfilm, accepted for R2-D2, and there was a message on behalf of “HAL” from Arthur C. Clarke, who lives in Sri Lanka.

Two key actors from the original Star Wars trilogy were also on hand for the celebration –David Prowse, who played Darth Vader in the original Star Wars Trilogy, and Kenny Baker who played R2-D2 in the first Star Wars episode.

The Robot Hall of Fame Web site , developed by Wall-to-Wall Studios of Pittsburgh, was unveiled at the ceremony.

The Robot Hall of Fame was established earlier this year to honor noteworthy robots, both real and fictional, along with their creators in recognition of the increasing benefits robots are bringing to society.

“Our goal is to create a permanent, interactive exhibition involving robots that will educate and entertain a wide variety of audiences,” said James H. Morris, dean of Carnegie Mellon’s School of Computer Science who conceived the Hall of Fame concept. Morris put together a panel of 13 experts, drawn from organizations around the world, to choose the robots to be enshrined in the Hall of Fame. Each of them will serve a two-year term.

Anyone may suggest a robot for the Hall of Fame. This time, the jury made its final selections from a field of 32 nominees via an international Web conference last September.

The criteria for choosing the robots depend on whether they are scientific, fictional or entertainment-oriented. Scientific robots must have served an actual or potentially useful function and demonstrated real skills in accomplishing the purpose for which they were created. Robots created to entertain must be functioning autonomous devices and have achieved a significant audience. Fictional robots should have achieved worldwide fame as fictional characters and helped to form our opinions about the function and value of all robots.

“It’s fitting that the Robot Hall of Fame is located here in Pittsburgh at the home of Carnegie Mellon’s Robotics Institute,” said Chuck Thorpe, the institute’s director. “We have been doing research in many areas of robotics for nearly 25 years and have helped to focus attention on this field that has so much potential to help people. Next year the Robotics Institute will celebrate its 25th anniversary. We will hold the next induction ceremony at that celebration, which takes place from Oct. 13-16, 2004.”
