A Multi-Modal Neuro-Symbolic Approach for Spatial Reasoning-Based Visual Grounding in Robotics
Visual reasoning, particularly spatial reasoning in robotics, is challenging, as existing Vision-Language Models (VLMs) struggle with fine-grained spatial understanding due to their implicit, correlation-driven reasoning. This paper proposes a novel neuro-symbolic framework that integrates panoramic-image and 3D point cloud information, combining neural perception and symbolic reasoning to explicitly model spatial and logical relationships. The framework detects entities, extracts attributes, and constructs a structured scene graph for precise queries. Evaluated on the JRDB-Reasoning dataset, it achieves superior performance and reliability in crowded, human-built environments with a lightweight design suitable for robotics and embodied AI.

Comprehensive Scene Understanding
Our framework integrates both panoramic images and 3D point cloud data, providing a comprehensive understanding of the scene. This multi-modal fusion allows for robust spatial reasoning, overcoming the limitations of models relying solely on 2D visual cues. The Projection Module precisely aligns semantic features with geometric relations, creating a rich scene graph.
This capability is crucial for accurately determining object locations relative to a robot (Relative Robot Positioning) and understanding complex human-object interactions in crowded, human-built environments.
Explicit and Interpretable Decisions
A novel symbolic graph search module is at the core of our reasoning component. It explicitly encodes spatial and logical relationships, allowing for precise and interpretable queries. Unlike implicit, correlation-driven reasoning in traditional VLMs, our approach grounds inference in explicit geometric and logical structures, significantly reducing errors and enhancing reliability.
The Graph Search Module employs a two-phase filtering algorithm, first selecting candidates based on attributes, then strictly validating relational constraints. This ensures both robust candidate selection and accurate relational reasoning, leading to high-performance spatial understanding.
Optimized for Real-World Deployment
Despite achieving superior performance in complex spatial reasoning tasks, our framework maintains a lightweight design, requiring significantly fewer parameters (1.3B) compared to many state-of-the-art reasoning-capable VLMs (e.g., Ovis2.5-9B at 9B parameters). This efficiency makes it particularly suitable for robotics and embodied AI applications where computational resources are often constrained.
The modular architecture allows for flexible integration of various model backbones, demonstrating the framework's ability to uplift capabilities even with suboptimal baseline performance, as shown in our targeted experiments with Qwen2.5-VL-3B-Instruct.
Bridging the Gap in Spatial Reasoning
Existing Vision-Language Models (VLMs) struggle with fine-grained spatial reasoning due to their reliance on implicit, correlation-driven inference. Our neuro-symbolic approach directly addresses this by integrating explicit geometric and logical structures, overcoming limitations in reliability and interpretability.

Real-World Robotics Application: Enhanced Navigation and Interaction
In a busy warehouse, an autonomous mobile robot (AMR) is tasked with retrieving a specific item located 'to the left of the yellow crate, behind the tall blue shelf, next to a worker wearing a red vest.' Traditional VLMs often struggle with this complex, multi-hop spatial query, potentially misidentifying locations or the target worker, leading to delays and errors.
Our neuro-symbolic framework, however, leverages its explicit scene graph and 3D understanding. It processes the visual input, identifies workers and objects, and constructs relationships based on their relative positions in 3D space. The query is parsed into symbolic constraints ('worker with red vest' -> 'left of yellow crate' -> 'behind blue shelf'). The graph search algorithm accurately identifies the target worker and the item's precise location, guiding the AMR to successfully complete its task.
This approach significantly reduces mission failure rates due to spatial misinterpretation, improves efficiency in dynamic environments, and enhances human-robot collaboration by enabling more natural and reliable language-based commands.
