Water Adaptive Limber Locomotive Effector (WALL-E)

There are many celestial bodies in the Solar System that have the potential for harboring life such as the moons Europa and Enceladus; these worlds hide away vast oceans under thick layers of ice. The potential for these bodies to contain other lifeforms has piqued the interest of organizations on Earth, such as the National Aeronautics and Space Administration (NASA), as destinations for future missions. Because of the distances and relatively harsh conditions involved, Remotely Operated Vehicles (ROVs) would be sent on the initial missions to explore these worlds. The NASA Jet Propulsion Laboratory (JPL) has developed a remotely-operated Mini-Arm for use on an ROV. This mini arm would be used to explore the oceans of these distant worlds. However, it is in need of an end effector capable of manipulating objects of interest; this was the task of the Boise State University Microgravity Team. During the course of the 2018-2019 school year, the team designed and fabricated WALL-E as a flexible and dexterous solution to subsurface gripping. The design, degrees of freedom, and simple user interface allow the operator to easily manipulate samples of varying dimensions and geometries, akin to those potentially found on the aforementioned ocean worlds
