We present a novel approach that incorporates information from sonar and infrared sensors mounted on a rotating platform to obtain feature-based stochastic maps of the environment. The purpose is to reliably determine the position of a robot and the features in its environment using low cost sensors. Line and corner features are extracted from the sonar(More)
The U.S. Environmental Protection Agency (EPA) is developing a New Generation Model (NGM) to more accurately predict in-use vehicle emissions at the micro-, meso-, and macro-scales. One of the characteristics of the NGM is that it should be able to predict emissions based on data collected from in-use vehicles under actual operating conditions. By contrast,(More)
