Investigators from the University of Basel developed a semi-autonomous quadruped robot called ANYmal, designed to accelerate the exploration of extraterrestrial environments such as Mars and the Moon.
Unlike traditional rovers, this robot resembles a robotic dog and is equipped with an arm that carries a microscopic camera and a Raman spectrometer, capable of identifying the chemical footprint of rocks.
Trials in Simulated Conditions
The tests were conducted at the Marslabor, a facility that replicates the dusty and rocky surfaces of Mars and the Moon. The goal was for ANYmal to move autonomously, identify rocks of scientific interest, analyze them, and transmit results without human intervention.
The results were surprising: the robot completed the missions in 12 to 23 minutes, while a human operator needed 41 minutes for the same task. Although human supervision offered greater detail, the speed and autonomy of the robot mark a significant change in the pace of space exploration.
Capabilities and Findings
ANYmal managed to identify minerals such as gypsum, carbonates, basalts, dunite, and anorthosite, materials relevant for understanding Martian and lunar geology.
Its legged design allows it to overcome obstacles and access areas inaccessible to wheeled rovers, expanding research possibilities in complex terrains.

Implications for Space Exploration
The study confirms that robots with autonomous mobility could become protagonists of scientific activity on other worlds. Instead of being simple remotely controlled tools, these systems would be capable of independently searching for biosignatures and traces of ancient life.
In the case of the Moon, the development of robots is crucial for investigating hostile environments, searching for resources like water ice, and building infrastructures without risking human lives. These machines would allow for the preparation of permanent bases, analysis of complex terrains, and reduction of mission costs.
A Future with Robot Protagonists
The research highlights the importance of robots in space exploration:
- They can perform dangerous tasks, such as exploring shadowed craters or handling radioactive materials.
- They facilitate the search for essential resources to generate oxygen and fuel.
- They contribute to the construction of habitats and landing platforms.
- They support manned missions in equipment maintenance and operation.
Projects like the ESA’s Moon Room and developments by NASA are essential for testing the resilience of these technologies in extreme conditions. ANYmal joins this trend, showing that quadruped robots could be key in the next stage of lunar and Martian exploration.
