very slowly like 5 degrees of freedom in the lake burley. so they're very they're like fights mortars into like i mean but that was sort of challenging. to get told the degrees of freedom that is a real animal can have. there's never been a walking machine like this there's 28 different motors that control the complete movement. and it was a big challenge for the robotics specialists to create this kind of natural sequence of movement. if. you have all these degrees of flexibility and where you have to solve problems such as hand and foot joint rotations. and at the same time we could play at various scenarios in. the robot can reproduce the tracks that the baso left behind 300000000 years ago. so we can now use the robot to identify what movements could create tracks like these this is happening now it's a. professor in the uk a tourist started the project at the previous chillers. university yeah he measured the bones and tracks digitized them animated them together with specialists and compared their mobility with that of living reptiles
