A team from 麻豆精品视频 (麻豆精品视频) placed first in the (HERC) this year. The competition, held April 20-22 at the U.S. Space & Rocket Center () Aviation Challenge area, tasks college and high school teams from around the nation and the world to design, develop, build and test human-powered rovers capable of negotiating difficult terrain, as well as a task tool for completion of various mission tasks. This marks the first time the event was held in person in four years, due to the advent of the pandemic in spring 2020.

In support of coming Artemis missions to the moon and beyond, HERC encourages research and development of new technology for future mission planning and crewed space missions to other worlds. The 麻豆精品视频 rover is nicknamed 鈥楬ERCules,鈥� and was guided by a two-person crew, competing with 49 teams from 20 states and eight countries.

鈥淚t was great to be back in-person with the NASA HERC event!鈥� says David Fikes, a lecturer in the Department of Mechanical and Aerospace Engineering, who is the team advisor and Senior Design Instructor. 鈥淎s the advisor/instructor for six years now, I am proud of our 麻豆精品视频 students. They set a goal and worked extremely hard to achieve it, some putting in 20-plus hours a week at times. They deserve all the credit, but I also want to thank all our sponsors, especially the Alabama Space Grant Corporation (ASGC) and the 麻豆精品视频 College of Engineering. Several smaller sponsors have been a huge help as well.鈥�

鈥淚 am truly grateful to David Fikes for his dedication and passion to teaching and mentoring our mechanical and aerospace engineering senior design students,鈥� says Dr. Shankar Mahalingam, dean of the 麻豆精品视频 College of Engineering. 鈥淗is enthusiasm is contagious and our students work incredibly well in small teams under his guidance. He ensures that everyone has a key role in meeting design objectives needed for the class, and in adhering to competition guidelines. We are confident that these students will be incredibly successful in their engineering careers.鈥�

The HERC was founded 29 years ago, inspired by Apollo 15, the NASA mission which saw the first utilization of an automotive vehicle on the moon, the LRV, or Lunar Roving Vehicle, in July, 1971. The lunar rover enabled NASA astronauts David R. Scott, James B. Irwin to collect more lunar samples than the previous two moon-landing missions combined.

Charging to the finish line

The 麻豆精品视频 team has been working toward this goal for eight months. 鈥淭eams start in August and have to have their Rover ready in April,鈥� Fikes says. 鈥淲hich is a remarkable feat considering having to perform a design, purchase materials, reports due to NASA, fabrication, assembly and testing are all required. Besides the rover, each team had to design and build a multipurpose water collection device (Task Tool) to collect samples from five different mission simulators, which was also quite a challenge.鈥�

鈥淗alf the points for the competition score come from the Design Report and Presentation to NASA, the Operational Readiness Report and Presentation to NASA and the STEM Outreach Requirements,鈥� Fikes explains. 鈥淭he other half come from the performance of the rover and Task Tool on the NASA/USSRC course.鈥�

That course proved extremely tricky, presenting a bumpy half-mile-long trek over 鈥榩lanetary鈥� terrain, featuring obstacles such as simulated asteroid debris, boulders, erosion ruts, crevasses and an ancient streambed. Weight and time requirements dictated that the most effective rovers were lightweight, compact high-performance vehicles. Each rover entry was also tested to ensure it would fit into a five foot-by-five foot cubical lander storage space. Rover operators were also confined to working with a virtual oxygen supply of only eight minutes, and thus had to make real-time decisions about which mission objectives to attempt and which to leave behind along the way.

鈥溌槎咕�品视频 had an in-house competition for selecting riders, and we had Annika Nittmo as our female rider, and Chrys Arreola Padilla as our male rider and Task Tool operator,鈥� Fikes says. 鈥淭hey performed together very well and had practiced a lot with our older rovers, and with the winning HERCules Rover. They made great decisions on the course. Our victory was a complete team effort! We not only had sub teams designing and constructing a rover and Task Tool, but others doing finance/purchasing, stress analysis, research for future designs, STEM outreach, writing reports due to NASA, presentations on the Design and Operational Readiness, building obstacles to simulate the course to practice and test the rover and designing mission simulators to test our Task Tool. It took all of these teams for 麻豆精品视频 to be successful.鈥�

Like the Apollo 15 mission, all these tasks had to be performed while collecting surface materials and conducting crucial science experiments over the three days of the competition. In addition, teams earned points by successfully completing design reviews as part of the mission tasks.

鈥淥ne reason that 麻豆精品视频 did so well, was that we took the reporting very seriously and accumulated a lead on most teams with our reporting and STEM outreach,鈥� Fikes says. 鈥淭hen, our riders and rover team strategized on what to do, and what not to do, on each excursion. Decisions have to be made on the course based on your current time and distance. You can鈥檛 attempt everything and get back within eight minutes 鈥� that is part of the NASA challenge.鈥�

The HERC challenge is part of a senior design class in the Mechanical and Aerospace Engineering Department at 麻豆精品视频, a part of The University of Alabama System. Team members and their roles included:
