One interest in this research effort was to develop and test an automatic control approach to adjust machine motions to the force conditions encountered during excavation - essentially...

Application of Automation and Robotics to Lunar Surface Human Exploration Operations
Major results of a study (RLSO, 89) applying automation and robotics to lunar surface base buildup and operations concepts are reported. The study developed a reference base scenario with...

Site Constraints for a Lunar Base
A rigorous site plan is a prerequisite for quantitative analyses of lunar base operations. The development of such a site plan, done for a detailed lunar base study (RLSO, 89), is described...

Lunar Base Elements Designed for Robotic Operations
Equipment concepts developed for a study of robotic lunar surface operations are presented. The concepts were evolved together with a consistent robotic buildup and operations scenario;...

Manifesting for a Lunar Robotic, Oxygen-Producing Base
Using robotic systems and human supervisory control, a lunar base reasonably be established to achieve full production within five years. Intermittent human presence works in coordination...

A Robotic Return to the Moon
An autonomous Lunar precursor mission is proposed as the first step to an effective, low cost return of man to the Lunar surface. The mission would use two self similar robotic vehicles...

A Robotics Testbed for In-Space Assembly Tasks
The operations testbed of the Center for Space Construction at the University of Colorado is described. This testbed serves as a centralized testing environment for interdisciplinary research...

Explosive Metal Working for Space
As the United States looks towards larger and larger lift vehicles for the transportation of the space station and other large payloads, the application of explosive metalworking becomes...

Prefabrication of Ceramic Segments by Compaction and Microwave Fusion Technology
Material source and environmental impacts are two major concerns in the application of conventional concrete technology in lunar base construction. In this study, the simulated lunar soil...

Unusual Spacecraft Materials
For particularly innovative space exploration missions, unusual requirements are levied on the structural components of the spacecraft. In many cases, the preferred solution is the utilization...

Motion Control of Space Structures
A new area of civil engineering is emerging as we begin to establish a permanent presence in space. The new area of civil engineering is the motion control of space structures. This paper...

Effects of Initial Conditions on Large Space Structures
Effects of initial conditions of axial deformation (length) and attitude (pitch) angle have been investigated on the subsequent orbital motion, attitude (librational) motion, and axial...
