Meet ZiGGY from EV Safe Charge: a mobile charging robot that can be implemented anywhere and summoned via an app. It comes with displays on both sides to show ads. It also has tail and head lights, a safety sensor band and 4 cameras on all sides. ZiGGY is smart enough to return to its charging station to get powered up from the grid, battery, or solar.
ZiGGY can be used to offer on-demand EV charging as a service. The above video shows what it is all about. More information is available here.
