Hardware design of a grappling/docking device accommodating large lateral and angular misalignments

Abstract

In this hardware project, continued from last year, the students developed ideas for a new grappling and docking mechanism that would be able to accommodate a very large initial misalignment (up to one half of the spacecraft radius) and simultaneously a large angular misalignment (up to 20 degrees) between space tug and space vehicle. The students were made familiar with the project by visiting TRW, where they could study the prototype of the NASA Orbiting Maneuvering Vehicle (OMV, since canceled). The students' objective was to design a model, built in the University machine shop, that would demonstrate the potential for much larger misalignments than was possible with the OMV.
