And once it has a self-model, it can use that to derive a pattern of locomotion.
It turned out that more than 100 years of research on spinal cord physiology, starting with the Nobel Prize Sherrington, had shown that the spinal cord, below most injuries, contained all the necessary and sufficient neural networks to coordinate locomotion, but because input from the brain is interrupted, they are in a nonfunctional state, like kind of dormant.
It turned out that there are known neural pathways coming from the brain that play this very function during locomotion.
I was completely fascinated by this locomotion without the brain, but at the same time so frustrated.
This locomotion was completely involuntary.
We refined our paradigm, and after several months of training, the otherwise paralyzed rat could stand, and whenever she decided, initiated full weight-bearing locomotion to sprint towards the rewards.
In fact, not only could the rat initiate and sustain locomotion on the ground, they could even adjust leg movement, for example, to resist gravity in order to climb a staircase.
This defines a personalized electrochemical neuroprosthesis that will enable locomotion during training with a newly designed supporting system.
And my hope is that after several months of training, there may be enough remodeling of residual connection to allow locomotion without the robot, maybe even without pharmacology or stimulation.
Our research on the biomechanics of animal locomotion has allowed us to make a blueprint for a foot.
We need mechanisms like legs and efficient motors in order to support that locomotion, and we need the sensors, power and control in order to pull everything together in a semi-intelligent ant robot.
But in order to look at mobility and locomotion at this size scale to start, we're cheating and using magnets.
But when I'm really small, the forces between my feet and the ground are going to affect my locomotion a lot more than my mass, which is what causes that bouncy motion.
Indeed, we designed it together with neurobiologists to understand how animals move, and especially how the spinal cord controls locomotion.
But the more I work in biorobotics, the more I'm really impressed by animal locomotion.
It has to coordinate more or less 200 muscles perfectly, because if the coordination is bad, we fall over or we do bad locomotion.
There are four main components behind animal locomotion.
The first component is just the body, and in fact we should never underestimate to what extent the biomechanics already simplify locomotion in animals.
And these input signals coming from descending modulation from higher parts of the brain, like the motor cortex, the cerebellum, the basal ganglia, will all modulate activity of the spinal cord while we do locomotion.
But what's interesting is to what extent just a low-level component, the spinal cord, together with the body, already solve a big part of the locomotion problem.
You probably know it by the fact that you can cut the head off a chicken, it can still run for a while, showing that just the lower part, spinal cord and body, already solve a big part of locomotion.
A second difficulty is that locomotion is really due to a very complex and very dynamic interaction between these four components.
So it's good to start with simple animals like lampreys, which are very primitive fish, and then gradually go toward more complex locomotion, like in salamanders, but also in cats and in humans, in mammals.
Like, more or less 20 years ago I was already working on a computer making simulations of lamprey and salamander locomotion during my PhD.
It makes a wonderful link between swimming, as you find it in eels or fish, and quadruped locomotion, as you see in mammals, in cats and humans.
And this really shows that the spinal cord is a very sophisticated locomotion controller.
So we studied salamander locomotion in more detail, and we had in fact access to a very nice X-ray video machine from Professor Martin Fischer in Jena University in Germany.
And what's interesting is that the salamander has kept a very primitive circuit, which is very similar to the one we find in the lamprey, this primitive eel-like fish, and it looks like during evolution, new neural oscillators have been added to control the limbs, to do the leg locomotion.
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.
