What we will create together in Part 2
- Build an environment to remotely control your agent anytime, anywhere using Telegram on your smartphone.
- Complete a household account book routine where a single receipt photo is automatically analyzed and recorded using Gemini 2.5 Flash's vision capabilities.
- Upgrade the Docker + workspace environment created in Part 1 into a real-world automation scenario.
Especially recommended for these people
- Those who say, "Now I want to use agents on my smartphone without a browser."
- Those who want AI to automatically classify and record receipt/image data instead of manually organizing it every time.
- Those who want to connect OpenClaw, which they only got a taste of in Part 1, to actual work/life automation.
Part 2 Core Curriculum at a Glance
- Section 1: Part 1 environment check and "Agent in My Pocket" scenario orientation.
- Section 2: Creating a Telegram bot with BotFather → Pairing → Real-time connection with OpenClaw agent.
- Section 3: Send receipt photos via Telegram → Automatic extraction of date, business name, amount, and items → Automation of cumulative storage in the expenses/ folder.
Pre-course Checklist
- It is best if you have the Docker container and Gemini API key used in Part 1 ready.
- Even if you haven't taken Part 1, you can set up the minimum required environment by following the “Hands-on Environment Pre-check List” provided in Part 2.
