FOFOCA is an open-source reference design for an AI-governed household robot, built around a Raspberry Pi 5 brain, an ESP32 for real-time motor control and sensor polling, and an ESP32-C3 driving an OLED status display over MQTT. This article walks through the hardware architecture, the firmware running on each Espressif chip, and how all of it connects to a local edge AI server running NVIDIA Nemotron Nano 8B for inference — no cloud dependency required.
This guide demonstrates how to integrate external libraries into NuttX applications using static libraries and cross-compilation. Learn how to build a library on x86, integrate it into the NuttX simulation environment, and cross-compile for RISC-V targets like the ESP32-C6, all without moving your entire codebase into the NuttX directory structure.
As security expectations rise globally - driven by region-specific cybersecurity regulations - safeguarding device credentials has become critical for IoT manufacturers. This article explains how the ESP-TEE framework integrates with Matter and demonstrates building secure products using the Espressif RISC-V SoCs, showcasing hardware-enforced security that can resist scalable remote software attacks.
