This article describes the software architecture of an autonomous, interactive tour-guide robot. It presents a modular and distributed software architecture, which integrates localization, mapping, collision avoidance, planning, and various modules concerned with user interaction and Web-based telepresence. At its heart, the software approach relies on probabilistic computation, on-line learning, and any-time algorithms. It enables robots to operate safely, reliably, and at high speeds in highly dynamic environments, and does not require any modifications of the environment to aid the robot's
The Education Development Center (EDC) is implementing the national expansion and institutionalization of the Playing to Win (PTW) Network. With the goal of working toward universal technology enfranchisement and prior support from the NSF Informal Science Education Program, the PTW Network currently links close to fifty agencies in a mutually supportive community of neighborhood technology learning centers serving people living in low-income areas who otherwise would have little or no access to computer-based technologies. The purposes of this phase of the project are: - to increase the number of affiliates nationally - to provide effective support for their technology programs and to do so in a planned and thoughtful manner which also is flexible and responsive to the flows, demands, and unforeseen opportunities fro community technology center development -- to move the affiliate membership toward independence and self-governance. Each year of the project, PTW will work in collaboration with the United Neighborhood Centers of America, the Alliance fro Community Media, NTIA-funded programs, FreeNets, and others in three to four target areas of the US to recruitment additional primary affiliates. The goal is to add 20 additional affiliates annually who will be supported by local coordinators and another 30 with subsidized telecommunications support. PTW plans to enrich programmatic content at the centers with special emphasis on math and science. The network will support an on-line math and science program consultant and continue to recruit and support affiliates with a math/science program emphasis. The Co-Principal Investigators for the project will be Myles Gordon, Director of EDC's Center for Learning, Teaching and Technology, and Antonia Stone, Founder of PTW and PI for the previous phases of the project.

The Louisville Science Center will develop "The World We Create", a 13,000 sq. ft. exhibit which will transform their second floor to an active learning environment where visitors can explore the simplest element of the creative process to the most sophisticated networks available to our society. The activities will be organized into five core exhibit areas: New Way Tunnel, Think Tank, Inventor's Garage, Chemistry Kitchen, and Tech World and will reinforce educational reform activities in math, science, problem- solving, team cooperation, and decision making. In addition to the large number of interactives, there is a substantial technology/telecommunications component known as the Tech Forum. This will serve at the home site for the Kentucky TeleLinking Network (KTLN). The educational objectives of the exhibit were developed under the guidance of prominent formal educators in the state and they address both the education reform goals of the state and national science and math standards. The exhibit has also been developed with direct participation of a number of private sector partners. It is an impressive community effort. The exhibit is scheduled to open in March, 1997.
The Great Lakes Science Center plans to enhance an existing facility by adding the Great Lakes Situation Room. This addition makes innovative use of live theater techniques to provide interactive programming for the visiting audience. The Great Lakes Science Center is a relatively new addition to the Informal Science arena but the visitation has double the expected projections. The programs for the situation room are: Science and Information Technology Show; Great Lakes Data Quest; My Own House Data Quest; and Mathematics All Around Us. These new programs, linked to the Great Lakes Environment and exhibitions throughout the facility will further enable the visitor to actually learn about science, environment, and technology using a unique format and "state of the arts" tools made available by informational technology. This project will impact a large, diverse audience in the Great Lake's area and beyond. It has the potential for replication in other museums and science centers. The goals of this project are to enhance the visitor's experiences and learning while at the science center. The themes for the programs will explore some popular topics among the visiting audience. This is a three-year project that will quintuple the programming capacity of the theater, enhance its role in providing Informal Science Education, provide new active learning experiences and expand the center's capacity for accommodating larger audiences of families and school students. The cost sharing for this award is 66.5% of the projected total budget.
