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.

Weight

80kg176lbOur conversion from 80 kg. The manufacturer does not state an imperial figure itself, so the conversion has no source of its own.

124 quadrupeds state a weight

HyQ2Max

11 state a higher figure, 109 a lower one. 1 more states exactly the same figure. Log scale: each step along the axis multiplies the value.

Degrees of freedom

12DoF

76 quadrupeds state degrees of freedom

HyQ2Max

15 state a higher figure, 4 a lower one. 56 more state exactly the same figure.

Notes

A robust hydraulic quadruped from IIT's Dynamic Legged Systems lab, built with aerospace-grade aluminum and titanium alloys and a glass-fiber shell.

Served as the direct development bridge leading to IIT's next hydraulic quadruped generation.
