It sounds too good to be true: a store on wheels that comes to you. That's exactly what Moby Mart promises. This autonomous, staffless mobile store offers up milk, medicine, clothes, and even electronics on-demand, with an app that not only summons the store but also serves as the checkout. Developed by Wheelys in collaboration with Hefei University and Himalafy, the Moby is also self-powered, relying on solar panels to provide energy for the electric drivetrain, while an integrated air purifier cleans the air around it — making it very eco-friendly. The company estimates that each store will cost under $100,000, and the concept is currently beta testing in Shanghai.
