There are roughly 863 million people living in slums, with that number continuously rising, according to the World Health Organization.
That's a massive issue, especially when you factor in Maslow's hierarchy of needs, a theory in psychology that outlines the basic needs of humans. As Berok Khoshnevis, a professor of engineering at the University of Southern California, points out, shelter is considered a fundamental need in Maslow's pyramid.
That's why Khoshnevis wants to tackle the world's housing crisis head on using tech. Scroll down to see his plan.
Khoshnevis is the inventor of Contour Crafting, a method that uses a giant robot to layer concrete to build houses.

The 3D-printing method ensures all the conduits for electrical, plumbing and air-conditioning are set up once the house is complete.
There's a lot of perks to the 3D-printing method. First of all, it's much faster than using human workers.
The robot can build a 2,000 square-foot house with all the utilities for electrical plumbing in less than 24 hours.
"In the case of natural disaster and war, a lot of people ask, 'what's the advantage of building a house in one day?' Khoshnevis, pictured below, told Tech Insider.

"A lot of people lose their houses in one second if there's an earthquake, flooding, whatever. Definitely those people want their houses in one day," he continued.
