Yes, there is a basket. The basket is placed on the floor next to the door.
```

**Analysis**:
- ✅ "Yes" response!
- ✅ Basket recognized
- ✅ Floor mentioned
- ✅ Location detail

**Score**: 40/100 (YES 대답했는데 왜 낮은 점수? - 색상 미언급)

**Prompt**:
```
<grounding> What objects are on the floor?
```

**VLM Response**:

- ⚠️ Floor mentioned
- ❌ 실제 objects 미인식

**Score**: 10/100 (Open-ended는 여전히 약함)

---

## 💡 핵심 발견

### 1. Structured Prompts 효과 증명 ✅

```
Structured (color + type):     70/100 ✅
Focused (type only):           30-40/100 ⚠️
Open-ended (general):          10/100 ❌

→ Structured prompts with JSON hint 필수!
```

---

### 2. 실제 Objects = Red Ball보다 낮지만 충분함

```
Red Ball (generated):          80/100 ⭐⭐⭐⭐⭐
Brown Pot (real):              70/100 ⭐⭐⭐⭐
Gray Basket (real):            70/100 ⭐⭐⭐⭐
Blue Mug (generated):          70/100 ⭐⭐⭐⭐

→ 70점도 navigation에 충분!
```

---

### 3. 두 Objects 모두 사용 가능!

```
Brown Pot:      70% → TARGET ✅
Gray Basket:    70% → OBSTACLE ✅

→ 이미 보유 중! 바로 시작 가능!
```

---

## 🎯 Navigation Feasibility

### Brown Pot as TARGET

**VLM Recognition**: 70/100 ✅

**Expected Navigation Success**:
```
Current baseline (bottle/box):
  VLM: 20% → Navigation: 60-70%

Brown Pot:
  VLM: 70% → Navigation: 80-85% (예상)
  
Improvement: +10-15% ✅
```

**Feasibility**: ✅ **Good! LoRA 없이 가능**

---

### Gray Basket as OBSTACLE

**VLM Recognition**: 70/100 ✅

**Obstacle Detection**: Sufficient for avoidance
