The ESP32 WiFi robot is a shrunken-down version of the ZeroBot. Instead of a Raspberry Pi, it is powered by the similarly popular ESP32. Despite its lower processing power, the ESP32 robot has a ton of features. It streams color video over WiFi, runs on a small LiPo battery and can be controlled accurately from any web browser.
