Turns out that there's a financial centre in Madrid, Spain which is so damn big and confusing to navigate that you'll desperately need these multilingual robots to guide you around. Here's how it works:
You stroll up to where the mechanical swarm is waiting, tip-tap your way through a menu on a robot's touchscreen to select your preferred language, pick a destination, and off you go.
The robots are about knee-high and zip back and forth through the Santander Group's financial complex in Madrid. They're clever enough to avoid running into people, other robots or any of the LED panel covered columns around the complex. [YDreams—Thanks, Carlos!]
