ETH Zurich quadruped robot solves giant Rubik’s Cube using only its feet
ETH Zurich Robotics Systems Lab released a video showing a quadruped robot autonomously solving a giant Rubik’s Cube using only its feet. The robot follows a three‑stage framework called Reflex that learns visual reactive whole‑body control step by step, linking stages through a compact object‑dynamics representation.
Key points
- ETH Zurich Robotics Systems Lab’s quadruped solves a giant Rubik’s Cube using only its feet.
- The robot uses the three‑stage Reflex framework for visual reactive whole‑body control.
- The video is featured in IEEE Spectrum’s “Video Friday” series showcasing advanced loco‑manipulation.
The demonstration highlights the robot’s ability to anticipate and react to a moving target within about a second, a capability that remains difficult for humanoid platforms. The video appears in IEEE Spectrum’s “Video Friday” series, which also referenced KAIST’s humanoid pushing objects up to 35 kg, AthenaZero’s fingers closing in about 80 milliseconds, and ETH Zurich’s bio‑hybrid actuators.
Researchers suggest the Reflex approach could be applied to tasks such as robot laundry folding or other manipulation problems, though the article does not provide quantitative performance metrics beyond the visual success of the Rubik’s Cube solve.
