# Embodied navigation systems lack a unified framework to compare and integrate diverse approaches, leading to fragmented progress and overlooked challenges like long-horizon planning and social compliance.

**Domain**: `Planning_Decision`

## Fix

Use the TOFRA five-stage pipeline (Transition, Observation, Fusion, Reward-policy construction, Action) to structure navigation systems, integrating sensing, social, and motion intelligence across stages.

## Anti-pattern

Ad-hoc navigation stacks that treat perception, planning, and control as isolated modules without cross-stage integration.

## Cross-domain analogies

- **Perception_Vision** → Propose a unified framework that fuses diverse planning approaches into a single comparative representation.
  - related fix: Propose a multimodal occupancy perception system that fuses vision, depth, and other sensor data into a unified occupancy representation for humanoid robots.
- **Learning_Training** → ScaleVLN's synthetic data diversity mechanism could unify navigation benchmarks via procedurally generated social and long-horizon scenarios.
  - related fix: ScaleVLN: large-scale synthetic data generation by combining 3D scene graphs with LLM-generated instructions and augmenting with panoramic views and object-level grounding.
- **Control_Locomotion** → Multi-expert distillation with DAgger enables unified policy integration and iterative refinement for long-horizon social navigation.
  - related fix: Multi-expert distillation with DAgger and RL fine-tuning, using depth images as exteroceptive input.
