A small robot with facial expressions, created for your desktop.
Designed at Central Saint Martins, London. Engineered in Cambridge.
The team.
Software engineering is led by a first-class Cambridge mathematics graduate,
working alongside a team of UK mathematicians researching the benefits of
fully secure on-device agentic AI in a personal robot this size.
The hardware.
A Raspberry Pi Zero 2W behind a 240×320 ST7789 display, powered over
USB-C. Out of the box it broadcasts its own wifi network — you join
that from your phone and hand it yours.
The shell.
3D printed in biodegradable materials made from fermented plant-based
starches. It looks good, and it is kind to the planet.
The intelligence.
Inside is zeroclaw, an agent written in Rust — a language that makes
very small, very fast programs, which is what lets one run on a computer
this size at all. Its reasoning, its memory and its tools all live on the
device, in a few megabytes of RAM. It reaches out to Anthropic's models to
think, and to you over WhatsApp.
Your data.
The services on the device talk to each other over loopback, with nothing
exposed. Your messages stay on your nunu-xo.
