The release also reworks the main loop and watchdog, adds measured optimizations, introduces native ESP-IDF toolchain support alongside PlatformIO, modernizes audio decoding, expands OTA capabilities, and adds ESP32-based Zigbee and multi-room audio components. ### Source excerpt ESPHome 2026.5.0 launches the public beta of the new ESPHome Device Builder, reworks the main loop and watchdog, and modernizes the audio decoder pipeline. ## Building FOFOCA: An Open-Source AI Robot with ESP32, ESP32-C3, and Edge AI DevFeed: [Building FOFOCA: An Open-Source AI Robot with ESP32, ESP32-C3, and Edge AI]() Original publisher: [Read original article]() Author: John Lee Published: 2026-05-15T00:00:00Z Content type: tutorial Language: en Sources: [Blog on Developer Portal]() Topics: [ESP32](), [Embedded Software Dev](), [ESP32-C3](), [Espressif](), [Raspberry Pi](), [Hardware](), [MQTT](), [Open Source](), [Nemotron](), [Cloud]() Tags: [ai](), [api](), [architecture](), [ble](), [blog](), [bluetooth](), [building](), [computer-vision](), [edge](), [edge-ai](), [esp32](), [esp32-c3](), [espressif](), [firmware](), [hardware](), [microcontrollers](), [mqtt](), [nemotron](), [nvidia](), [open-source](), [pwm](), [raspberry-pi](), [real-time](), [risc-v](), [robotics]() ### AI overview This article presents FOFOCA, an open-source household robot reference design using an ESP32 for real-time motor and sensor control, an ESP32-C3 for an MQTT-connected OLED display, and a Raspberry Pi 5 as the processing brain. A local Dell R210 server runs NVIDIA Nemotron Nano 8B and supporting services, while ThinkNEO provides AI governance and audit routing. ### Source excerpt 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.
