At the World Economic Forum in Davos, the Swiss inventors demonstrated a unique Skaterbot robot, which, on its four limbs, moved well on the ice on skates.
The basis of the development of engineers from the Swissof the higher technical school (Zurich), software was taken that allows designing various robots moving in semi-automatic mode with the help of limbs with wheels fixed on them. Announced Skaterbot is an improved version of the "wheeled" brother, who has skates on the "legs". In the demo video, you can see that the robot skater moves freely on the ice and performs maneuvers left and right.
