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 (~0.3s)
Easy and cheap to build using widely available components
Print the two shells with the inside facing the print bed. You will need to include a lot of support material. Simplify3D works best for this, but Slic3r or Cura with optimized settings should be fine as well. I used support with lower density for the most part and higher density for the last 8 layer up to the part. This saves a lot of filament.
The tires should be printed with Ninjaflex or something equivalent to ensure good grip.
Everything else can be printed in PLA.
