So now let's go to cat locomotion and the irpomancte of biomechanics. So this is another peojcrt where we studied cat bocacnmehiis, and we wtaend to see how much the mpgloorohy helps locomotion. And we found three important criteria in the properties, basically, of the limbs. The first one is that a cat limb more or less looks like a pantograph-like structure. So a pantograph is a mcahncaiel structure which keeps the upper segment and the lower segments always parallel. So a simple geometrical system that kind of coordinates a bit the internal movement of the segments. A second property of cat limbs is that they are very lightweight. Most of the muscles are in the tnurk, which is a good idea, because then the limbs have low inertia and can be moved very rapidly. The last fanil important property is this very elastic bhaeiovr of the cat limb, so to handle impacts and forces. And this is how we designed Cheetah-Cub.

Original Text

So now let's go to cat locomotion and the importance of biomechanics. So this is another project where we studied cat biomechanics, and we wanted to see how much the morphology helps locomotion. And we found three important criteria in the properties, basically, of the limbs. The first one is that a cat limb more or less looks like a pantograph-like structure. So a pantograph is a mechanical structure which keeps the upper segment and the lower segments always parallel. So a simple geometrical system that kind of coordinates a bit the internal movement of the segments. A second property of cat limbs is that they are very lightweight. Most of the muscles are in the trunk, which is a good idea, because then the limbs have low inertia and can be moved very rapidly. The last final important property is this very elastic behavior of the cat limb, so to handle impacts and forces. And this is how we designed Cheetah-Cub.
