In the shadow of Oregon’s majestic Mount Hood, a team of researchers from a consortium of universities and NASA’s Johnson Space Center have embarked on a groundbreaking project. Their mission? To prepare a dog-like robot named Spirit for the daunting task of navigating the moon’s unpredictable terrain.

Spirit’s rigorous training regime
During a rigorous five-day testing period in the summer of 2023, Spirit faced a gauntlet of challenges. The quadruped robot, equipped with spindly metal legs, traversed shifting earth, mushy snow, and rocky obstacles. “A legged robot needs to be able to detect what is happening when it interacts with the ground underneath and rapidly adjust its locomotion strategies accordingly,” explains Feifei Qian, the project lead from the USC Viterbi School of Engineering.

SUIT UP FOR THE STARS: SPACEX’S NEW ERA OF SPACE FASHION
The LASSIE Project: A leap towards planetary exploration
Spirit’s trials are part of the LASSIE Project (Legged Autonomous Surface Science in Analog Environments), a multidisciplinary effort that includes engineers, cognitive scientists, geoscientists, and planetary scientists. The team’s goal is to understand the characteristics of different substrates and enhance the robot’s ability to walk on these challenging surfaces.

Collaborative robotics: The future of space exploration
Looking ahead, Qian’s team plans to develop more quadrupeds to advance their mission. With a $2 million grant from NASA, the TRUSSES Project (Temporarily, Robots Unite to Surmount Sandy Entrapments, Then Separate) aims to deploy groups of robots to the moon. These robots will share knowledge and form a map of locomotion risk estimation to aid in their planetary explorations.

Kurt’s key takeaways
The Palmer Glacier on Oregon’s Mount Hood isn’t the moon, but it’s an excellent place for practice. Here, Spirit and its future robotic companions learn to navigate extreme terrains, transforming into structures like bridges or pyramids to overcome obstacles. This research not only pushes the boundaries of technology but also inspires us to reimagine the possibilities of teamwork in the face of adversity.
