Mr. Jason Bailey


The Arkansas Razornauts are developing a prototype that is meant to be a resource-collecting rover attachment, but could easily be iterated to be a self-propelled digging apparatus. The teams’ prototype specializes in loose aggregate collection in the 0-1 square inch range and prioritizes collection attempts. The prototype is loosely based on an excavator on Earth as it features linear arm movement and a digging field of roughly 160 degrees. However, it differentiates from an excavator because the prototype incorporates a hollow arm that allows sample movement and storage within the body of the prototype.
