WALK OR ROLL
Ever wonder how many steps you take in a day? Or why our big toes are no longer opposable? How would you design a robot to walk? Care to take a bumpy ride through a detailed history of the bicycle or travel west with the pioneers? Wheeled vehicles, a two-page spread on shoes, and plenty of additional activities for curious minds keep this lively issue on the move!
