Rapidly evolving sensor, effector and processing technologies, including micromechanical fabrication techniques, will soon make possible the development of very inexpensive autonomous mobile devices with adequate processing but fairly limited sensor capabilities. One goal which has been proposed is to employ large numbers (more than 100) of these simple(More)
In two previous papers we explored some of the systems aspects of applying large numbers of inexpensive robots to real world applications. The concept of coverage can help the user of such a system visualize its overall function and performance in mission-relevant terms, and thereby support necessary system command control functions. An important class of(More)
The Segway Robotic Mobility Platform (RMP) is a new mobile robotic platform based on the self-balancing Segway Human Transporter (HT). The Segway RMP is faster, cheaper, and more agile than existing comparable platforms. It is also rugged, has a small footprint, a zero turning radius, and yet can carry a greater payload. The new geometry of the platform(More)
ROBART III is an advanced demonstration platform for non-lethal security response measures, incorporating reflexive teleoperated control concepts developed on the earlier ROBART II system. The addition of threat-response capability to the detection and assessment features developed on previous systems (ROBART I and ROBART II) has been motivated by increased(More)
A system comprising a large number of identical and very inexpensive robotic search vehicles may serve as an effective tool in a variety of MCM operations, providing improved mine detection and clearance capabilities while reducing cost and the physical risk to MCM personnel. Moreover, the many-robot approach to addressing MCM applications becomes(More)
This paper discusses some communications issues relevant to a system consisting of an arbitrarily large number of simple autonomous robots, from several different perspectives: (a) in the language of traditional communications systems analysis, (b) by analogy with biological systems, and (c) as a problem of intelligent control and data fusion. Emphasis is(More)
This paper proposes a conceptual design for a distributed system of very simple robots capable of performing a useful realworld mission such as mapping the interior of a building overnight with a swarm of possibly hundreds of cockroach-sized robots. Presentation of this system concept follows an initial discussion of strategies for developing distributed(More)
Communications and communications protocols will play an important role in mobile robot systems able to address real world applications. A poorly integrated "stack" of communications protocols, or protocols which are poorly matched to the functional and performance characteristics of the underlying physical communications links, can greatly reduce the(More)
It is widely recognized that simulation is pivotal to vehicle development, whether manned or unmanned. There are few dedicated choices, however, for those wishing to perform realistic, end-to-end simulations of unmanned ground vehicles (UGVs). The Virtual Autonomous Navigation Environment (VANE), under development by US Army Engineer Research and(More)
The Mobile Detection Assessment and Response System robotic security program has successfully demonstrated simultaneous control of multiple robots navigating autonomously within an operational warehouse environment. This real-world warehouse installation required adapting a navigational paradigm designed for highly structured environments such as office(More)
