The directions were mostly right. Every distance was invented. Giving Jambu Better Ears https://www.jambuvan.app/journey/05-giving-jambu-better-ears/ https://www.jambuvan.app/journey/05-giving-jambu-better-ears/ Sun, 19 Jul 2026 00:00:00 GMT Building Jambu 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. Teaching Jambu to Listen and Move https://www.jambuvan.app/journey/04-teaching-jambu-to-listen-and-move/ https://www.jambuvan.app/journey/04-teaching-jambu-to-listen-and-move/ Fri, 17 Jul 2026 00:00:00 GMT Building Jambu The milestone this whole project was building toward: saying 'Jambu, move forward' out loud and watching real wheels respond — entirely offline. First Wheels Spin https://www.jambuvan.app/journey/03-first-wheels-spin/ https://www.jambuvan.app/journey/03-first-wheels-spin/ Fri, 17 Jul 2026 00:00:00 GMT Building Jambu 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. Solving the Mystery Wires https://www.jambuvan.app/journey/02-solving-the-mystery-wires/ https://www.jambuvan.app/journey/02-solving-the-mystery-wires/ Thu, 16 Jul 2026 00:00:00 GMT Building Jambu Each motor came with six wires and zero documentation on which two actually spin it. A multimeter and a little patience settled it.

Step one of giving it a body: a chassis, some wheels, and a motor driver.
