Istanbul Airport is 30 miles out of the city, on the Black Sea coast. It can transport up to 200 million people each year.

"We're starting to get to dimensions that we once thought were unrealistic," he told New York Times Andrew Thomas, a partner at the Grimshaw Design Company, which designed the Istanbul airport. "It doesn't matter what you put in it, if the walk is so long and tiring for people, from the entrance to their gate."

At Mongkutwatana Hospital in Bangkok, they needed help moving paperwork mountains earlier this year, using the assistance of robots dressed in bright yellow dresses and long brown wigs, helping to move the archive to its new location.
