ALTIUS SPACE MACHINES, INC. — National Aeronautics and Space Administration STTR Phase I: T4

Description

The ESCHER interface is part of a larger concept working to enable swarms of robots to autonomously perform difficult construction tasks while minimizing the cost and complexity of doing so. The interface, designed by Altius for use on Virginia Tech#39;s FASER Lab robots, will leverage existing switchable electropermanent magnetnbsp;(EPM) technology and Altius custom geometries to provide a high holding force magnetic interface that uses no moving parts and no transient power. The ESCHER interface aims to act as a universal interface, acting not only as the end effector for robotic manipulators, but also as an interface between modular structures, modular robots, individual robots acting as part of a swarm, and between robots and the structures they are manipulating.nbsp;During Phase I of this project Altius will leverage their existing technologies, along with FASERrsquo;s in-house robotics and algorithm development experience to: 1) Define the mechanical and structural requirements of the ESCHER interface and develop an initial conceptual design, 2) Develop and algorithm that enables the use of the ESCHER interface to perform cooperative robotic assembly tasks, 3) Design, build, and test a brass-board level prototype of the ESCHER interface, 4) Perform an integration of the interface prototype, the developed algorithm, and the existing robotics and demonstrate basic functionality of all systems working together, and 5) Define power and data transfer needs of the interface for integration in a Phase II effort.nbsp; The Phase II effort would aim to raise the TRL level of the interface to a 6, explore the full solution space of potential applications of the universal ESCHER interface, and finally perform a demonstration of fully autonomous cooperative assembly of a structure using the interfaces and algorithms developed through Phase I and II.
