U.S. experts have developed what they say that are biologically accurate robot legs yet.
Writing in the journal of neural engineering, they said that the work on consultation understanding like babies and spinal injury treatment learning could help.
They created a version of the message system, rhythmic muscle signals generated that the control on foot.
A UK expert said that the work was exciting, because the robot mimics control and not just movement.
The team from the University of Arizona, could the Central pattern generator (CPG) - a nerve cell to replicate, (neuronal) network in the lumbar region of the spinal cord that rhythmic muscle generated signals.
The CPG produces and then controls, these signals by collecting information from different parts of the body involved in walking, respond to the environment.
This is what people, to go without thinking about.
The simplest form of a CPG is a half Center, which consists of only two neurons that produce either fire signals a rhythm as the sensors, which provide information, for example. If a leg back to the half Center meets a surface.
The University of Arizona team suggests babies start with this simple building - and then in the course of time develop a more complex pattern on foot.
They say this may explain, has seen why babies put on a treadmill started - even before they learned to walk.
Writing in the journal, the team says: "this robot is a complete physical, or 'Neurorobotic'-based model of the system, demonstrate the usefulness of this type of Robotics Research for the neuropsychological study go in humans and animals".
Dr. Theresa Klein, who in the study worked, said: "Interestingly we a foot gear, could control the lower extremities without producing balance, which mimicked human control of the hip and a number of reflex responses with only a simple half-Centre."
"This underlying network can also form the core of the CPG and could explain how people with spinal cord injuries to walk can regain ability, if stimulated correctly in the months after the injury."
Matt Thornton, gait analysis laboratory head at the British Royal National Orthopaedic Hospital, said that the work "an interesting development" was.
He added: "back robot models have imitated human movement: this continues and mimics the underlying human control mechanisms driving this movement."
"It could be to examine a new approach and to understand the relationship between nervous system control and hiking provide pathologies."
Mr. Thornton said existing systems for the analysis of how people walk, so called gait analysis carried out by the RNOH and others common movements in 3D, run exactly measure hips, knees and ankles while patients on a treadmill. Patients react differently depending on their condition.
He added: "at present this analysis provides us with detailed information about joints, bones and muscles."
"The robot model can go a step further in linking these problems of the nervous system, which actually controls the movement."
"Increased to understand the impact, such as patients with spinal cord injury are very exciting."
