Sure thing. Here’s a quick low‑budget blueprint that keeps things pragmatic: 1. **Base chassis** – a small mobile platform (like a Roomba‑size robot) with a stepper‑driven wheel set, a 5‑V buck converter, and a microcontroller (ESP32 is great because it has Wi‑Fi and BLE). 2. **Joke module** – load a small library of pre‑written jokes onto the ESP32 flash. Use a text‑to‑speech library (e.g., eSpeak) to vocalise them. Trigger a new joke every time the robot performs a diagnostic routine or finishes a task. 3. **Wi‑Fi diagnostics** – program the ESP32 to scan for APs, ping the router, measure RSSI, and run a simple TCP throughput test. Log the results to a local file or send them over MQTT to your phone. 4. **Display & feedback** – a tiny OLED for status, a small speaker for jokes, and LED indicators for “connected,” “error,” or “joke queued.” 5. **Power** – a 12‑V Li‑Po pack with a built‑in 5‑V regulator; add a power‑management board to switch to the regulator only when diagnostics run. 6. **Assembly** – solder the ESP32, speaker, and OLED to a perfboard. Mount everything in a plastic case with a clear front for the speaker. 7. **Firmware** – keep the main loop simple: `scanWiFi(); diagnose(); if (diagnosis OK) {playJoke();} delay(30s); repeat`. That’s the skeleton. Flesh it out with actual code snippets and component specs, and you’ll have a joke‑telling, Wi‑Fi‑fixing helper in no time.
