The cerebellar motor control has been well trained, and the brain's on-the-spot analysis of the unfamiliar environments also has to be developed. The two-legged one needs the higher balance feedback control than one with more than four legs, and the cost is higher. Although the demand of the military is the ground sneaking reptiles better than the erect humankind and even asks the joints to rotate omnidirectionally: the most perfect artificial creature is the roll ball which can extend out the omnidirectionally rotating legs, arms, and wings from the whole surface of the sphere; except the humankind can and be willing to self-modify the gene, the human-like bodies will be always needed forever. And it is not expected to connect the neural mechanical body only after the natural body is damaged, so it is necessary to redesign the axis center rotation robot to become the anexoskeleton rotation armor one like the IronMan.
