quadruped

Although the team’s quadruped still has some trouble with slippery surfaces and visually noisy environments like tall grass, the progress remains incredibly impressive ahead of the project’s big debut at next month’s Conference on Robot Learning.

Donkey kicks, which are also called quadruped bent-knee hip extensions, involve getting on all fours and, while keeping your back flat, lifting one bent leg at a time straight back and up as high as you can until your back starts to arch.

There could not, indeed, be stronger evidence that man has descended from a quadruped ancestor.

But these species have returned to the quadruped habit, to which the equal length of their limbs adapts them.
