Space Bok is redefining locomotion for space exploration

Legged robotics with all its advantages can be used in space to improve the exploration of the Moon or Mars.
In low gravity environments hopping proves to be energetically more efficient than walking.

Our aim is to build a jumping robot capable of overcoming large obstacles and thus increase the operation range of mobile robots for data collection.

Wheeled locomotion has been used exstensively for planetary exploration. Due to its stability and relatively low complexity, a space rover can be used for many different applications. However, when it comes to sandy, rough or steep terrain, wheeled robots reach their limitations. This is where legged robotics comes into play. A walking robot can overcome various obstacles and rarely gets stuck in sanddunes. Especially a jumping form of locomotion becomes more energy efficient on celestial bodies such as our Moon, Mars or Europa, one of Jupiters moons.This type of movement would open up new possibilities to gather interesting data from craters or canyons.

Every year, students attending the fifth semester of Bachelor's Programs in different disciplines of engineering can apply for a Focus Project. Teams of up to 14 students from the ETH, ZHAW or ZhdK, work during two semesters on the realisation of a market-oriented product. With the support of an ETH Professor and a coaching team, the optimal solution to a complex problem has to be found.

The final goal is to present a physical prototype on the Focus Roll-Out in May.
