Skill: Receptacle Operator

Skill: Receptacle Operator

When to Use

Use this skill when you need to:

1. Access a closed receptacle to place an object inside or take an object out.
2. Secure an open receptacle after accessing it (e.g., to conserve energy, maintain cleanliness, or complete a task step).

Core Decision Logic

1. Check the receptacle's state from the observation.
   • If it reports "is closed" or "is open", note the state.
   • If the interior is visible (e.g., "In it, you see..."), it is open.
2. Choose action based on goal:
   • Goal requires interior access (e.g., "put in microwave", "take from fridge"):
     • If closed → open {recep}
     • If open → proceed with next step (e.g., put or take)
   • Goal requires securing receptacle (e.g., after accessing, or for efficiency):
     • If open → close {recep}
     • If closed → no action needed
3. Execute the action using the exact format: Action: open {recep} or Action: close {recep}

Example from Trajectory

• Task: "cool some tomato and put it in microwave"
• Step 1: At closed fridge → Action: open fridge 1
• Step 2: After checking interior → Action: close fridge 1 (for efficiency)
• Step 3: At closed microwave → Action: open microwave 1

Important Notes

• Always verify the receptacle state from the latest observation before acting.
• The skill only handles open and close actions. Other actions (like take, put, cool) are separate skills.
• If "Nothing happened" is observed after your action, the receptacle may already be in that state—re-check and adjust.
