ROBOT GUIDES SUBWAY RIDER IN LONDON
Twirling a dial helps subway riders find their way, at a self-service information booth just opened in London, England. To inquire how to reach any point in the city, the traveler sets the dial according to a printed list of instructions. The device then informs him of the place’s location, the exact fare required, and the number of the platform from which the appropriate train leaves.
