Offline-first home robot
Meet Jambu — a voice assistant that grew wheels.
Jambu listens, understands, and now moves — all running locally on a Raspberry Pi, with no cloud round-trip required. Built in the open, one solved wiring puzzle at a time.
How it works
From spoken word to spinning wheel.
A command goes in through the microphone, gets transcribed and understood entirely on-device, and comes out the other side as real motor movement — no internet connection required.

Giving Jambu Better Ears
A single-mic USB microphone gets overwhelmed fast on a moving robot. Upgrading to a proper 4-mic array with real beamforming fixed problems we didn't even know we had yet.

First Wheels Spin
With the motor wiring solved, the drive system got its first real bench test — both wheels spinning on command, battery-powered, no laptop tether required.

Teaching Jambu to Listen and Move
The milestone this whole project was building toward: saying 'Jambu, move forward' out loud and watching real wheels respond — entirely offline.
