Levo / robot


Fallen leaves in city streets are unattractive and useless. They bother drivers and walkers, so they are collected and incinerated, a process which requires labor and pollutes the air.

“Levo” is designed to turn fallen leaves into organic fertilizer and save labor. “Levo” is a robot with artificial intelligence who collects fallen leaves and converts them to compost by adding a mixture of water and microorganisms, and wrapping the product. The compost from “Levo” is nature-friendly and economical.
