The 2007 Darpa grand challenge is a 100 km race between autonomous vehicles in an urban environment. This paper presents the results of kinematic motion study in order to quantify the minimum perception range requirements of a canonical set of manoeuvres that are required for the event. The paper also considers the potential advantage that a course reversal strategy may provide competitors that...

This paper reports on various aspects of the Intelligent Vehicle Systems (IVS) team’s involvement in the recent 2007 DARPA Urban Challenge, wherein our platform, the autonomous “XAV-250,” competed as one of the 11 finalists qualifying for the event. We provide a candid discussion of the hardware and software design process that led to our team’s entry, along with lessons learned at this event a...

Overview This paper is written as background for a proposed Grand Challenge in Computing Research, entitled Science for Global Ubiquitous Computing. The paper has a specific purpose: to trace the evolution of theoretical models for distributed and mobile computing, and the mutual influence between these models on the one hand and software design and development on the other. It also discusses m...

We present a case study in the design of an autonomous robotic software subsystem for managing mission execution and discrete traffic interaction in the 2007 DARPA Urban Challenge. Its role is reviewed in the context of the overall software system that controls “Boss”, Tartan Racing’s winning entry in the competition. Design criteria are presented, followed by the application of design principl...

In November 2007 the international competition DARPA Urban Challenge took place on the former George Airforce Base in Victorville, California to significantly promote the research and development on autonomously driving vehicles for urban environments. In the final race only eleven out of initially 89 competitors participated and “Boss” from Carnegie Mellon University succeeded. This paper summ...

It is now commonplace to see the Web as a platform that can harness the collective abilities of large numbers of people to accomplish tasks with unprecedented speed, accuracy and scale [10]. To push this idea to its limit, DARPA launched its Network Challenge, which aimed to “explore the roles the Internet and social networking play in the timely communication, wide-area team-building, and urge...

purpose: hidden caries is a term used to describe occlusal dentine caries that is missed on a visual examination, but can be detected by bitewing radiographs. the aim of this study is the review of new studies about this lesion and presentation the ways for diagnosis, prevention and treatmen of this lesion. review of literature: investigations believe that the etiology of this lesion is the mor...

abstract: fortunately in recent years in iran, semiotics arguments in literature and art study are noticed by researchers. in according to, the denotation and connotation functions in photography are updated and expanded. thus, necessary bases for continuing this argument are available. although denotation and connotation are belong to semiotics area, but in photography, specially critique of p...

A novel probabilistic perception algorithm is presented as a real-time joint solution to data association, object tracking, and object classification for an autonomous ground vehicle in all-weather conditions. The presented algorithm extends a Rao-Blackwellized Particle Filter originally built with a particle filter for data association and a Kalman filter for multi-object tracking (Miller et a...
