ZeroBot is a Raspberry Pi Zero W based robot. It can be controlled using any computer or smartphone via a web browser. The integrated camera module makes for a low latency video stream. In addition the Raspberry Pi acts as a Wifi access point, so no router is required. The parts for the hull as well as the wheels can easily be printed on any regular 3D printer. Some of the key features are: - Compact CAD design with 3D printed components; - Analog control via a joystick (and multitouch); - Simple battery solution using only a standard power bank; - Low latency streaming (~0.2s); - Easy and cheap to build using widely available components “
