According to a group of researchers, the robotic walking leg simulation in the video below is the closest we've come to being able to replicate the way biological organisms move. To some, it will be impressive. To me, it's still pretty weird looking. You decide - am I being too picky?
A key component of the human walking system is the central pattern generator (CPG). The CPG is a neural 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 that are responding to the environment. This is what allows people to walk without needing to think about it.
