Core Workflow

1. Identify Need: Determine which object is required for your current or upcoming task (e.g., "thermometer", "metal pot").
2. Locate Object: Ensure you are in the correct room. Use look around to survey the environment and confirm the object is present and accessible.
3. Execute Fetch: Use the pick up action on the target object.
4. Verify Success: Confirm the system observation states the object has been moved to your inventory.

Key Principles

• Pre-check: Always look around first to verify the object's presence and location (e.g., on a counter, in a container).
• Direct Action: Use the simple pick up OBJ command. Do not overcomplicate the sequence.
• Inventory Focus: After picking up the object, you may focus on it in your inventory to signal readiness for the next step in your main task.
• Error Handling: If pick up fails, the object might be inside a closed container. Ensure all relevant containers are open first.
