The robots are equipped with iPhone cameras and LiDAR sensors that help create the digital twin of the robot and its surroundings.<\/figcaption><\/figure>\n<p>The team uses RE-RASSOR, the Research and Education Regolith Advanced Surface Systems Operations Robot, a low-cost, 3D-printed educational platform adapted from NASA\u2019s original RASSOR mining robot.<\/p>\n<p>Each rover costs approximately $400 to produce, allowing students to experiment with digital twin software on comparatively inexpensive hardware, says Gray, a <a href=\"https:\/\/www.ucf.edu\/degree\/mechanical-engineering-bsme\/\">mechanical engineering<\/a> alum. That accessibility could make advanced robotics research more feasible for university laboratories with limited resources.<\/p>\n<p>During a demonstration, Gray showed how an iPhone\u2019s camera and LiDAR sensor, mounted on the rover, help the system construct a 3D virtual representation of the robot and its surroundings in real time.<\/p>\n<p>\u201cIt\u2019s a two-way street. The robot is constantly sending its position \u2014 you can move it in the digital twin, and then that will be sent to the robot. &#8230; At the end of the day, you want them mirroring each other,\u201d Gray says.<\/p>\n<p>Rabelo says a digital twin\u2019s update frequency must reflect the behavior of the physical system it represents. For robotic systems, that means accounting for changes second by second rather than relying on the longer-term predictions used in conventional simulations.<\/p>\n<p>\u201cThe digital twin depends on the time constant of the system,\u201d Rabelo says. \u201cThat\u2019s the difference.\u201d<\/p>\n<p>That connection between physical and virtual systems could help operators make more informed decisions in unfamiliar lunar or planetary terrain.<\/p>\n<p>\u201cSay on the moon, if the environment is very bumpy, rocky, you might not always know if a command is going to be successful or not,\u201d Gray says. \u201cSo you can see in the simulation if it can go over this bump successfully. And then if it does, then you can do it on the real rover with a lot more confidence than if you didn\u2019t have the simulation.\u201d<\/p>\n<h2>Building on Earlier Research<\/h2>\n<p>The work grew out of a collaboration between UCF and the Universidad Polit\u00e9cnica de Durango in Mexico. During the 2025-26 academic year, Rabelo and Metzger advised an international senior design project focused on developing an AI-driven digital twin of RASSOR.<\/p>\n<p>A central objective was to investigate how digital twins could help operators work around communication delays. The farther a robot travels from Earth, the longer commands and information can take to pass between it and the people directing it.<\/p>\n<p>Rabelo describes a test scenario with a simulated three-second delay in each direction, creating a six-second round trip. The digital twin could help operators anticipate the rover\u2019s behavior and identify potential problems before they occur.<\/p>\n<h2>Preparing for Future Space Exploration<\/h2>\n<p>Rabelo envisions expanding the research beyond individual rovers to groups of autonomous robots collaborating on complex logistics tasks at the moon\u2019s south pole.<\/p>\n<p>Different robots could perform specialized tasks, from surveying terrain and identifying resources to collecting materials and transporting equipment. A shared digital twin could help coordinate their movements across a larger environment.<\/p>\n<p>\u201cYou have to have a bigger digital [twin] of the entire piece of the moon where all of those things have to go,\u201d Rabelo says.<\/p>\n<p>Such technology could eventually help researchers coordinate robotic operations across distant planetary environments, where communication delays make continuous human oversight difficult.<\/p>\n<p>For now, this student-built platform lays the groundwork for a larger ambition: helping future robotic teams explore farther, with operators better prepared for what comes next.<\/p>\n<hr>\n<p><em>The research received $5,000 in support from the Florida Space Grant Consortium through UCF\u2019s Florida Space Institute. Undergraduate senior design teams developed the rover prototypes under the guidance of Rabelo, Gray and Metzger.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>UCF researchers are
