Hobbyists in collaboration with Carnegie Mellon's Robotics Institute created 250 robots for Pittsburgh's 250th anniversary.

In 2006, the team from the CREATE Lab at Carnegie Mellon?s Robotics Institute were enjoying a rare quiet moment, sharing crêpes at a local eatery. Over the course of the meal, the idea of having a city-wide robotics celebration was conceived, and when the 250th anniversary of Pittsburgh came to light, the die was cast.

What is now known as Robot 250 became a massive city-wide community art and technology program culminating in a two-week festival this July with exhibits, workshops, outdoor displays, movies and other installations throughout the Pittsburgh area. It was launched by Carnegie Mellon University and the University of Pittsburgh with program support from a host of local community groups and financial support from local foundations.

The mission of Robot 250 is to foster creativity, build a sense of community and raise the technical literacy of our entire region, while coinciding with the city of Pittsburgh?s 250th anniversary celebration. Participants include middle school students, artists, families and the general public, as well as Carnegie Mellon, Georgia Tech and University of Pittsburgh faculty, staff and students, who are gathering to build customized robots using cutting-edge technology and educational materials developed at the Robotics Institute.
