Recently scientists have created machines that have the ability to balanwalk and run across rough and uneven terrain, making them far more useful in navigating human environments.

extraordinary feat of biomechanical engineering. Every step requires balance and the ability to adapt to instability in a split second. It requires quickly adjusting where your foot will land and calculating how much force to apply to change direction suddenly. No wonder, then, that until now robots have not been very good at it.
