This robotic vending machine could replace juice bars

But there isn't always a juice bar nearby, and store-bought juice is often not raw and contains preservatives. 

The Juicebot, a robotic vending machine that dispenses raw juice, could be a new, convenient alternative for juice drinkers.

The machine stores fresh juice and dispenses it in 8-ounce servings. Juicebot's chief research officer, Eric Ploeger, tells Tech Insider that the company presses the juices in a central kitchen, then refills the machines every 24 to 48 hours to ensure the drinks are always fresh. One kitchen can make enough juice to fill 75 bots.

The machines sit where people usually want raw juice: apartment buildings, gyms, malls, and yoga studios.

Although they're currently only available in San Francisco, Juicebots will come to New York City this summer, Ploeger says. 

Here's how they work.
