Engineers from the Georgia Institute of Technology have developed a prototype Assembly, which will actively help people to climb them.
New staircases are designed to significantly ease lifting it. Each rung of this ladder is equipped with springs (two right and left) and striker. When a person walks down the stairs, it's own weight bring level - stretches the springs, lowering the stage to the clamp. Upon further lifting of the person stepping on the steps, remove them from the clamp and they are slightly pushing his foot
