provide. At this point, the Carnegie Institute (under the leadership of Robert Wilburn) stepped in, showing interest in merging with the Buhl Institute. Both parties agreed to the merger in 1987. On October 5, 1989, construction began on the $40 million building, designed by local architect Tasso Katselas, which was renamed the Carnegie Science Center as a result of the merger. The Henry Buhl Jr. Planetarium and Observatory was reinvented in this new facility. The Center opened in October 1991. Roboworld The Roboworld area is the second-floor attraction at the Carnegie Science Center. It is touted as "the world's largest permanent robotics exhibition", with more than 30 interactive displays featuring "all things robotic". The first robot encounter in Roboworld is Andy Roid, the Robothespian, an interactive, animatronic robot that introduces visitors to the concepts of robotic sensing, processing and acting. The area's other exhibits showcase different types of robots and videos about them. Roboworld is also home to famous robots such as R2D2, Hal9000, C-3PO, and Gort. The Robot Hall of Fame features famous robots from science fiction films, television, and video games, such as R2-D2, C-3PO, Data, the T-800 Terminator, R.O.B., Maschinenmensch, Gort, Robby the Robot, Robot B-9, HAL 9000, and Huey, Dewey, and Louie from Silent Running. Highmark SportsWorks Highmark SportsWorks (formerly UPMC SportsWorks) is one of the major, permanent exhibits of the Carnegie Science Center. It is one of larger science and sports exhibitions in the world, with over 30 interactive experiences in which visitors can participate. The main idea of SportsWorks is "to inspire learning and curiosity by uniting the experience of sports for every age level with the laws of science that controls sports." SportsWorks features three themed areas: Physics of Sports (exploring the science of balance, trajectory, center of gravity, momentum, etc.), LifeWorks (featuring information for keeping a healthy lifestyle), and Sports Challenge (demonstrating various physical activities present in many sports). The previous sponsor, UPMC, ended its sponsorship of SportsWorks in 2006. On November 13, 2008, the Carnegie Science Center unveiled plans for a new SportsWorks, sponsored by Highmark. It reopened in the Fall of 2009. From October 8, 2007, until May 2008, SportsWorks housed the controversial exhibit BODIES... The Exhibition. At least one employee of the Carnegie Science Center left her job due to the implementation of this exhibit. A committee from Pittsburgh Regional Transit, then known as Port Authority, recommended in 2007
