About
Chennai Robotics and AI Builders
CRAB is a Chennai community for people who build physical and intelligent systems — robot arms and rover chassis, on-device models, RAG pipelines, and the messy middle where hardware meets software.
Why we exist
Too many builders learn alone. We host sessions where you can bring a half-finished project, ask for help on a motor driver, or walk through an idea on a whiteboard — then write it up so the next person does not start from zero.
What “builders” means
Students, professionals, hobbyists. If you are shipping something — a PCB, a dataset, a demo — you belong here. Titles matter less than the work on the table.
Online home
This site at crab.onl is where we publish articles and list events. The community itself lives in meetups and shared builds.
Get involved
Come to an event, propose a workshop, or contribute an article. Start with the articles feed — including the Vector Database Illustrated walkthrough — and say hello when you show up in person.
