Now SpaceBok, named after the bounding springbok antelope, is getting a Mars upgrade — on the Red Planet, it will have to weather much stronger gravity than on the Moon and face more treacherous terrain, as [*Wired* reports](). The concept is a strong one. If it were to ever land on Mars, a walking robot could explore terrain that has so far been off limits to wheeled rovers — and maybe even the [planet's mysterious caves](). https://youtu.be/oujhXCPSA-k ## Going for a Hike The sandy, rocky, and steep slopes of the inhospitable Martian surface make it a difficult terrain for a four-legged robot to cross. Special gaits and different kinds of feet, however, could give SpaceBok a big leg up. For instance, a "static" gait where at least three limbs make contact at a time, or planar feet — flat, snowshoe-like swiveling circles — could allow the tiny crawler to successfully tackle Mars' unforgiving terrain. They put the various configurations of the robot to the test inside a giant sandbox. Using flat feet, the robot was able to get up a steep 25-degree incline. "One of the surprise findings was that the point feet were not performing so bad on this particular slope, because of that high sinkage," ETH Zurich roboticist Hendrik Kolvenbach, lead author of [the associated paper](), told *Wired*. "Basically, they provide quite a stable stance." The team did note the flat feet caused the rover to use more energy, and is now looking at options that are somewhere between flat and pointy feet. In addition to [helicopters](), walking robots could soon stand the chance of venturing into the many still unexplored areas of Mars — one small step at a time. **READ MORE:** [How Do You Make a Robot Walk on Mars?

I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
