DESIGN OF AUTONOMOUS COUPLING MECHANISM FOR MODULAR RECONFIGURABLE LUNAR ROVERS by CHRIS LYKE Bachelor of Arts Honors Thesis Thayer School of Engineering Dartmouth College Hanover, New Hampshire Date: __________________________ Approved:______________________ Advisor’s Signature ______________________________ Author’s Signature Abstract Modular reconfigurable robotics consist of modules that can join together to form larger entities capable of changing their morphologies for improved versatility, robustness, and cost. Coupling mechanisms play a key role in these systems, as they are the component connecting the modules and enabling the robot to change shape. Coupling mechanisms also define the structure, rigidity, and function of modular systems. This paper details the development of the autonomous coupling mechanism for SHREWs, a modular reconfigurable system of rovers designed to explore the permanently shadowed regions of the Moon.

  • Bringing Space Textiles Down to Earth by Fi Forrest
    Feature Bringing Space Textiles Down to Earth By Fi Forrest DOI: 10.14504/ar.19.2.1 extiles are an essential part of the space industry. Every gram sent into orbit costs hundreds of thousands of dol- lars, so textiles must be lightweight as well as strong, and Tresistant to extremes of heat, cold, and ultraviolet radiation that they never have to experience down here on Earth. With the US National Aeronautics and Space Administration’s (NASA) recent announcement of a lunar spaceport—the Gate- way Project—and manned missions to Mars being proposed by Elon Musk, the next generation of space textiles are GO.1,2 In space you find textiles everywhere, from the straps that hold you in place during take-off to the parachute on your re-entry. Diapers are in your underwear, you might work in an inflat- able module on the International Space Station (ISS) and even that flag on the moon was specially designed in nylon. In space everything acts, and reacts, differently. Whether in low-gravity environments like the moon, or micro-gravity on the ISS, even the way moisture wicks away from the human body is different.
