Explanation / Answer

( a ) The major components involved in walking are the brain, eyes, and legs and feet. The input may be chosen as the desired walk direction, and the output the actual walk direction. The control action is determined by the eyes, which detect the difference between the input and output and send this information to the brain. The brain commands the legs and feet to walk in the prescribed direction. ( b ) Walking is a closed-loop operation because the control action is a function of the output. ( c ) If the eyes are closed, the feedback loop is broken and the system becomes open-loop. If the eyes are opened and closed periodically, the system becomes a sampled-data one, and wallung is usually more accurately controlled than with the eyes always closed. ( c ) If the eyes are closed, the feedback loop is broken and the system becomes open-loop. If the eyes are opened and closed periodically, the system becomes a sampled-data one, and wallung is usually more accurately controlled than with the eyes always closed.
