About

Who we are

We're a small student robotics team based in Bangladesh. We build autonomous hardware using locally available parts, document the whole process, and publish everything open-source.

The goal isn't to impress it's to build real things, learn from them, and make it easy for others to do the same.

Open source

Everything on GitHub files, schematics, build logs.

Local hardware

Parts that are actually available in Bangladesh.

Projects

What we're building

Each project is documented and published. Build on our work, or just follow along.

ACTIVE PROJECT ● Active
