Sage is a robot that has been installed at the Carnegie Museum of Natural History as a full-time autonomous member of the staff. Its goal is to provide educational content to museum visitors in order to augment their museum experience. This paper discusses all aspects of the related research and development. The functional obstacle avoidance system, which departs from the conventional occupancy grid-based approaches, is described. Sage's topological navigation system, using only color vision and odometric information, is also described. Long-term statistics provide a quantitative measure of

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 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 Computer Museum will develop two 2500 sq. ft. computer-based exhibits the "Virtual Fishtank: Splashing Into Complex Systems". One exhibit will be installed permanently in the Computer Museum and the other will travel nationally for three to five years. These exhibits will use computer modeling of fish to introduce the public to new ideas about complex systems science and demonstrate the central concept that complex behaviors and patterns can emerge from simple interactions among simple rules. Visitors will spend eight to ten minutes designing their own fish at one of the ten FishBuilder computer stations. As they make decisions, they will be able to observe the effects of their rule selections on a computer display. When satisfied with their design, visitors can then "tag" their fish by placing their initials on fish tails and launch them in the central "fishtank". Large projection screens will encircle visitors in a dramatic simulation of an underwater aquarium environment. Visitors will observe and analyze how the few simple rules imbedded in the design of individual fish give rise to complex behaviors and patterns in the entire ecosystem. This exhibit draws on research conducted at MIT's Media Lab, The Computer Museum, and the New England Aquarium and will be able to reach people with a variety of learning styles. It anticipated completion date is March, 1998 for the TCM's version and the traveling version will begin it's national tour in September, 1998.
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.
