how to make a robot that moves and talks？

Hey, cool project idea! The short answer is yes, the K10 can handle both motor control and voice — but you need to be realistic about what "LLM" means on this board.

The K10 runs on an ESP32-S3 with 512KB SRAM. That's plenty for motor control and basic voice stuff, but it's nowhere near enough to run an actual LLM locally. What you'd do is use the K10's built-in WiFi to call a cloud LLM API (like ChatGPT, DeepSeek, etc.) — the K10 handles voice input, sends text to the API, gets the response back, and plays it through the onboard speaker.

The good news is the K10 already has a lot of what you need built in: dual mics for voice recognition (supports both offline commands and online speech-to-text), a speaker for TTS, and WiFi to talk to the cloud. For motors, you just need a motor driver board connected through the Gravity I/O ports or the edge connector — something like a dual motor driver would let you control two TT motors for a basic wheeled platform.

There are actually people who've built voice-controlled robot cars with the K10 already — it's a pretty common project in the Chinese maker community. They use the offline speech recognition for basic commands like "go forward", "turn left", etc., which might be enough for your use case without even needing an LLM.

If you want actual conversational AI (ask questions, get smart answers), then yeah, you'd route that through a cloud API over WiFi. The K10 product page mentions support for DeepSeek and MCP, so the infrastructure is there.

For the robot platform itself, that tutorial you found is a solid starting point. A basic TT motor wheeled chassis + motor driver + K10 as the brain would get you moving. Then layer on the voice stuff.

Good luck with the build!
