Link: 'Most realistic' robot legs developed
“The team, from the University of Arizona, were able to replicate the central pattern generator (CPG) - a nerve cell (neuronal) network in the lumbar region of the spinal cord that generates rhythmic muscle signals.
The CPG produces, and then controls, these signals by gathering information from different parts of the body involved in walking, responding to the environment.
This is what allows people to walk without thinking about it.”
