From the project

autonomous robot car

Dit project is begonnen met het idee van mijn zwager om een robot karretje te maken Ik heb zelf een achtergrond in ontwikkeling van elektronica (microcontrollers, vermogens-elektronica en audio). Voor mijn zwager was dit onbekend gebied dus zoals wel vaker gebeurt heb ik mijn hulp aangeboden. Voor de ontwikkeling is er gebruik gemaakt van opensource software. Als OS heb ik Linux Fedora 44 desktop KDE plasma gebruikt. De uitdaging is om het karretje autonoom deze handelingen te laten uitvoeren, vooral het real-time karakter hierbij is een uitdaging. Eerst hebben we alles op een breadboardje…
