Impressive for such a compact design. Are you planning to add dynamic gait-switching?

[@georgehancock652]

From a biomimetic perspective why two joint rather than 3 joint limbs, as currently the stride length is really short. I would’ve thought that having a three joint limb would increase the stride engraved and well the amount of spring. If it’s truly beneficial to have a two joint. Limb then why do we only see knee driven locomotion in birds for which all modern ground dwelling species are secondarily terrestrial?

Maybe it was too heavy then? Idk I don’t know much about robots or anything but maybe they wanted it to be small, but fast? Again, not a robot person.

Each leg has 3 joints, not 2. It would not be able to turn as dynamically without the abduction joint. Read the paper

Fantastic project!

Cheetah 2 from 2016 was achieving 5.8m/s, this one only 3.7m/s

They are in different sizes

Why was the leg movement design changed from the previous version ?! is it more efficient or just because it is more adaptable?

It will all be over soon BWAHAHAHAA!
