Taking a single step for a human requires force, coordination, balance and direction. These entire factors present unique challenges for engineers to design a robot that can walk. New term experimented with the “dynamic balance” is introduced a feature that allows robots to maintain balance while walking. This new technology recently created a robot for testing that can walk. This new innovation can open the door for robot in military emergency operations or helping disabled individuals with their daily tasks. This technology is still in its developmental stage but we know that robot needs to walk before they can run.
