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.

Height

98cm38.6inOur conversion from 980 mm. The manufacturer does not state an imperial figure itself, so the conversion has no source of its own.

89 quadrupeds state a height

HyQ

1 states a higher figure, 87 a lower one.

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

HyQ

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

HyQ

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

Max speed

7.2km/h4.47mphOur conversion from 2 m/s. The manufacturer does not state an imperial figure itself, so the conversion has no source of its own.

Notes

A hydraulically actuated quadruped developed by the Dynamic Legged Systems lab at Istituto Italiano di Tecnologia, starting in 2010.

12 active joints powered by hydraulic cylinders and rotary actuators; a research predecessor to IIT's later hydraulic quadrupeds.
