    The resupply interface mechanism (1990)
    In:  CASI
    Details
    Publication Date: 2013-08-31
    Description: Viewgraphs on the resupply interface mechanism are presented. The major servicing activities for any major asset are normal maintenance, consumable replenishment, repair of failed components, and preplanned product improvement. Spacecraft propulsion system resupply can be divided into three major issues: design for servicing, servicing technology, and mechanization.

    A robot end effector exchange mechanism for space applications (1990)
    In:  CASI
    Details
    Publication Date: 2013-08-31
    Description: Efficient robot operation requires the use of specialized end effectors or tools for tasks. In spacecraft applications, the microgravity environment precludes the use of gravitational forces to retain the tools in holding fixture. As a result of this, a retention mechanism which forms a part of the tool storage container is required. A unique approach to this problem has resulted in the development of an end effector exchange mechanism that meets the requirements for spaceflight applications while avoiding the complexity usually involved. This mechanism uses multiple latching cams both on the manipulator and in the tool storage container, combined with a system of catch rings to provide retention in both locations and the required failure tolerance. Because of the cam configuration the mechanism operates passively, requiring no electrical commands except those needed to move the manipulator into position. Similarly, it inherently provides interlocks to prevent the release of one cam before its opposite number is engaged.

    Manned Mars Mission on-orbit operations metric development (1990)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: This report describes the effort made to develop a scoring system, or metric, for comparing astronaut Extra Vehicular Activity with various robotic options for the on-orbit assembly of a very large spacecraft, such as would be needed for a Manned Mars Mission. All trade studies comparing competing approaches to a specific task involve the use of some consistent and unbiased method for assigning a score, or rating factor, to each concept under consideration. The relative scores generated by the selected rating system provide the tool for deciding which of the approaches is the most desirable.
