DotBot hardware documents

This repository contains hardware projects for the DotBot robot: - the Kicad project for the main PCB and for the Lighthouse 2 shield PCB - the FreeCAD project for the mechanical parts (motor holders, ball caster wheel spacer and holder) that can be 3D printed - SVG files for the optional top hat. These files can be used with a laser cutter

This repository also provides a list of off-the-shelf components required to assemble the DotBot: - Pololu components (ball caster and encoder magnets) - Pololu wheels (if not using the 3D printed version) - Screws - Threaded inserts - 2 pins micro JST…
