Team Astrobotics from the University of Alabama received the top award, the Joe Kosmo Award for Excellence, at NASA’s Eighth Annual Robotic Mining Competition (RMC) awards ceremony May 26. The mining competition was held May 22-26 at the Kennedy Space Center Visitor Complex in Florida.


The RMC is a NASA Human Exploration and Operations Mission Directorate project designed to encourage students in science, technology, engineering and math, known as STEM fields. The project provides a competitive environment to foster innovative ideas and solutions that could be used on NASA’s Journey to Mars.

Joe Kosmo, for whom the top award is named, is a retired NASA engineer with a keen interest and background in robot mining. He served several years as an advisor and judge during the competition.


“It’s been a wonderful experience. It’s humbling,” said Joseph Kabalin, graduating senior and Team Astrobotics lead. “We know how hard it is to get here for the competition. Our hats are off to all of the other teams.”


Team Astrobotics took first place in the Robotic On-Site Mining category, collecting a total of 336 kilograms of regolith during two mining runs. Their robot accomplished all of the mining autonomously, without communication from the team or use of a remote-controlled device in the control room.


“Before we go to Mars, we need to learn about it. We need to pre-stage supplies and equipment,” said Kennedy Center Director Bob Cabana. “There’s a lot we can accomplish using robots.”


The weeklong competition featured teams of undergraduate and graduate students from 45 colleges and universities across the United States. They traveled with their robot miners to Kennedy from schools in Alaska, Hawaii, Utah, Vermont, the Commonwealth of Puerto Rico, and the Florida cities of Melbourne and Orlando.


Before traveling to the space coast, each team spent up to a year planning, designing, building and testing robots that can traverse in a mining arena filled with simulated Martian terrain or regolith, called BP-1, excavate the regolith and deposit it into a collector bin within 10 minutes.


Each team’s robot had two opportunities to traverse and excavate simulated Martian dirt, seeking to move and collect the most regolith, within a specified amount of time. Teams had to mine a combined total of at least 10 kilograms to qualify for the mining portion of the competition.


From control rooms near the mining area, teams monitored their autonomous robots or commanded their robots to perform the intricate movements required to collect the regolith and maneuver through the rocky terrain to the collector bin and complete the task. Hidden below the surface of the regolith was a layer of small rocks, representing ice water below the simulated regolith surface. This change brought the competition more in line with the requirements of future off-world mining missions.


Other RMC competition categories included submission of a systems engineering paper, and a slide presentation and robot demonstration. Also factored in was how well each team reached out to its community through social media and engagement with area schools and the general public.


Rob Mueller, lead judge for the mining competition, is a NASA senior technologist for Advanced Projects Development in the Exploration Research and Technology Directorate at Kennedy.


“Once again, the university teams showed a remarkable variety of designs for Mars mining robot prototypes,” Mueller said. “This year, many machines showed increasing sophistication of robotic perception sensors and autonomy software, reflecting the general advancement of available technologies with reduced costs.” 




Team Astrobotics from The University of Alabama won the top award, the Joe Kosmo Award for Excellence, and several other awards, during NASA’s 8th Annual Robotic Competition award ceremony May 26, inside the Apollo-Saturn V Center at the Kennedy Space Center Visitor Complex in Florida. More than 40 student teams from colleges and universities around the U.S. used their uniquely designed mining robots to dig in a supersized sandbox filled with BP-1, or simulated Martian soil, and participated in other competition requirements, May 22-26, at the visitor complex.

Several teams tried out new innovations this year, ranging from 3-D printed parts and twin robotic miners, to making adjustments or adding parts in real time to solve problems.

First-time participant was the Scarlet Space Hawks team from the Illinois Institute of Technology, Armour College of Engineering. They designed and built their robot, named “Lofty,” in just three months. Their efforts paid off with 72 kilograms of mined regolith and a third-place award in the Robotic On-Site Mining category. 


“It is mind-blowing, seeing all of the cool robots here,” said Shawn Zachariah, a junior studying electrical engineering. “We wanted to go with a simple design. We plan to return for the 2018 competition.”


Also a first-timer was Trickfire Robotics, from the University of Washington Bothell. They had some issues with their robot “Daybreak” tipping in the mining arena during practice runs.

“We added a third wheel in between the front and back wheels on both sides of our robot to help with stability, and it worked,” said team member Brian Gonzalez-Montoya.

In their eighth year of competition, the team from University of Nebraska-Lincoln improved on previous designs and used 3-D printed wheels, eight inches in diameter and five inches thick. The auger, or digger, also printed from composite material, was used to mine deep below the surface and bring a section of the regolith to the surface to scoop it up. Making more parts from 3-D printed composites helped reduce the robot’s weight.


Also in its eighth year at RMC, the Cyclone Space Mining Club from Iowa State University spent a full year building two robots, “Space Ketchup” and “Space Mustard.” According to Jakob Hartl, a graduating senior in aerospace engineering, the team focused on high efficiency and doubling the production capability of previous years. In the mining arena, one robot failed, but the second one continued to mine the regolith and deposit it in the collection bin.

Montana State University’s team took their design in a new direction. Their SCARAB robot’s tracks were designed to dig, much like an animal digs with its front paws, and send the regolith behind to its collector bin.


Mueller said the Robotic Mining Competition is important to NASA. Most of the resources available in space are contained in the regolith. In order to take advantage of these resources for in-situ resource utilization — living off the land — the regolith must first be excavated and then delivered to a processing plant to extract water, silicates and minerals.


“We are looking for ideas. We need small robots that can do big things,” said Pat Simpkins, director of Kennedy’s Engineering Directorate. “Robotics is hard, but robotics in space is doubly hard, whether it’s on the moon, Mars or another destination in space.”
