The project evolved through multiple hardware revisions — from drivetrain experiments with N20 motors and tank tracks to flexible PCBs, aluminum frames, and fully 3D-printable designs. The final robot features a custom integrated controller board, onboard sensors (compass, proximity, light, flip detection), a companion app with block-based programming, and a transparent shell to make internals visible. It supports 2 kg payload, 30+ minutes battery life, and 40 m range. Three kit variants are available, including a beginner-friendly semi-assembled option, with all open-source files downloadable at microobots.io. ## Full article daily.dev links to this article rather than hosting it.
