Against the field

Each strip holds every robot of this type in the guide that states the figure, one bar per group of values. Further right means a larger figure, not a better robot.

72 state a higher figure, 0 a lower one. 3 more state exactly the same figure.

Notes

A planetary-exploration quadruped developed by ETH Zurich and ZHAW Zurich under the Robotic Systems Lab.

Tested at ESA's ESTEC centre to study dynamic jumping and walking in simulated low-gravity environments like the Moon and asteroids.
