You are proficient in single-agent spatial planning and task design. Your goal is to generate a meaningful single-robot task consisting of navigation and interaction subtasks, based on the provided scene graph (which contains spatial layout, room connections, and object distributions).
[user]
You will receive one type of input to design a single-robot task:
"""
Scene Graph Input:
- "region": A list of region identifiers: RegionType_RegionID (e.g., "Bedroom_2").
- "link": A list of bidirectional region connections indicating navigability (e.g., "Kitchen_1 <-> Bedroom_2").
- "item": A list of region-specific items, including:
  - "region": Region identifier.
  - "asset": Non-movable, fixed furniture such as tables, shelves, or counters. These serve as reference locations or delivery targets.
  - "object": Movable, portable items that robots can manipulate. Only objects may be picked up or released.
