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.

Degrees of freedom

12DoF

76 quadrupeds state degrees of freedom

SCalf

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

Max speed

approximately 4.32km/happroximately 2.68mphOur conversion from 1.2 m/s. The manufacturer does not state an imperial figure itself, so the conversion has no source of its own.

113 quadrupeds state a top speed

SCalf

77 state a higher figure, 7 a lower one. 1 more states exactly the same figure.

Notes

SCalf-1 was the first Chinese hydraulic quadruped robot to achieve high-speed trot-gait walking, using an external hydraulic power station.

Developed at Shandong University's Center for Robotics; the work was later published in the journal ROBOT, and the same group founded Shandong Youbaote Intelligent Robot Co.
