Soon, robots may be able to mimic human gait.

A group of US researchers has produced a robotic set of legs which they believe is the first to fully model walking in a biologically accurate manner.The neural architecture, musculoskeletal architecture and sensory feedback pathways in humans have been simplified and built into the robot, giving it a remarkably human like walking gait. The robots biological accuracy has allowed the researchers to investigate the processes underlying walking in humans and may bolster theories of how babies learn to walk as well as helping to know how spinal cord injury can recover the the ability to walk, the journal of neural engineering reports. The key component of human walking system is pattern generator (CPG). CPG is a neural network in spinal cord region that generates rhythmic muscle signals
