## What this evaluates

Evaluates robotic navigation policies under diverse simulated environments, testing robustness to both precise and misleading natural language instructions.

## Datasets

- **CANVAS** — total ?; splits: test (-1)

## Metrics

- `success rate (%)` **(primary)** — range: percent
  - Percentage of successful navigation rollouts out of total attempts. Calculated as (number of successful episodes / total episodes) * 100.

## Input / output format

**Input**: Visual observations and natural language navigation instructions.

**Output**: Robot navigation commands (e.g., velocity or waypoint).

## Scoring recipe

```python
success_count = 0
for rollout in rollouts:
    if rollout.success:
        success_count += 1
success_rate = (success_count / len(rollouts)) * 100
```

## Common pitfalls

- Success rates are highly sensitive to instruction type (misleading vs. precise), so reporting a single aggregate score hides instruction-following robustness.
- The benchmark uses simulated environments, which may not capture real-world sensor noise or navigation obstacles.
