Turnkey Contractor Procurement for System Improvements
This paper describes the development of a procurement method and documents issued to bidders for improvements to the Docklands Light Railway, London, England. The bidders were required...
The Advantages of E & M Systems Procurement
Fifteen years of experience, observations and lessons gained by two of the leading turnkey contractors in the transit and large people mover market have led to the following conclusion:...
Implications of ISTEA on the Implementation of APMs
The Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991, approved 372-47 in the House and 79-8 in the Senate, is a landmark legislation in the area of transportation. Through...
Traversing the Terminals
When it opens this December, the Denver International airport will rely on an $89 million automated-people-mover, (APM) system as the primary means of transporting passengers between the...

Remote Automated Wave and Water Level Monitoring System Deployed at Agat Harbor, Guam
Agat Harbor, Guam is a small boat harbor excavated from a coral reef flat and protected by a detached breakwater. An automated monitoring system was designed and installed to observe wave...
The Roads Ahead
In 1990, 37 states spent almost $50 million on highway pavement crack sealing, according to researchers at the Strategic Highway Research Program (SHRP). In the near future, a robotic...
Automating The Corps
Automated soil testing machines solved several problems at once for the U.S. Army Corps of Engineers' South Western Division Laboratory in Dallas, Texas. The machines replaced...
An Expert System for Impeller Mechanical Design and Analysis
Impeller is the most critical component of centrifugal compressors. The mechanical efficiency and durability of the impeller determines the performance of the compressors. The shapes and...
Pattern Formation and Time-Dependence in Flowing Sand
The authors present results for a number of experiments on flowing granular materials and a novel cellular automata model for the flow of these materials when the grains are long and thin....
Human Exploration of Mars: The Role of a Mars Outpost Laboratory
The scientific exploration of Mars will require a systematic series of reconaissance missions (robotic and human) and detailed exploration at specific sites. The detailed exploration will...
Cables and Cranes for a Flexible Lunar Transportation System
This paper will discuss the results of preliminary research on a cable-based transportation system for the moon. The paper will address the principles of cableway design and will present...
Lunar Resource Base
A lunar base that exploits local resources to enhance the productivity of a total SEI scenario is discussed. The goals were to emphasize lunar science and to land men on Mars in 2016 using...
On-Orbit Assembly of Large Space Structures: A Mars Aerobrake Mock-up Study
As design requirements for space structures become larger in dimension, the issues of shipping and assembling these structures in space become more critical. One example of such a structure...
Ropeway Material Handling Systems for Lunar Mining Sites
The establishment of permanent lunar sites will be a requirement for future space explorations during early missions into space as well as long term. During all stages it will be necessary...
Principles of Control for Robotic Excavation
Excavation can be considered one of the most unstructured problems in the construction environment. On one hand, many technologies have been developed in the past to build shelters using...
On-Orbit Robotics Assembly and Operations of a Nuclear Mars Transfer System
This paper presents an operations concept and associated scenarios for assembly in Earth orbit of a manned Mars vehicle. The assembly of a Rockwell-Spar reference spacecraft configuration...
Robotic On-Orbit Fueling of SEI Vehicles
Space Exploration Initiative (SEI) missions may involve the assembly and then fueling of vehicles in locations other than on the surface of the Earth. For example, fueling of the Mars...
Modular Robot Testbed
One approach to non-terrestrial construction involves the use of small, inexpensive, modular robots rather than expensive one-of-a-kind construction tools. The Modular Robots Testbed at...
Outpost Service and Construction Robot (OSCR)
The Outpost Service and Construction Robot (OSCR) is proposed as the prime mover of a comprehensive, synergistic approach to extraterrestrial surface construction, mining and transportation...
