SAGA: Open-World Mobile Manipulation via Structured Affordance Grounding

The SAGA (Structured Affordance Grounding for Action) framework represents a significant leap forward in robotic control, enabling robots to perform diverse and complex mobile manipulation tasks in unstructured environments. By disentangling high-level semantic intent from low-level visuomotor control through explicit grounding of task objectives in 3D affordance heatmaps, SAGA enhances generalization across environments, tasks, and user specifications. This approach, leveraging multimodal foundation models, facilitates robust, data-efficient learning and supports zero-shot execution and few-shot adaptation via language, points, or demonstrations. Evaluated on a quadrupedal manipulator across eleven real-world tasks, SAGA consistently outperforms baselines, demonstrating a scalable pathway to generalist mobile manipulation.

Affordance-Entity Pairs Unified, Structured Task Objectives

Structured Affordance-Entity Pairs

SAGA introduces a novel task representation using affordance-entity pairs (e.g., {grasp: 'duster handle', function: 'duster head'}). This allows expression of diverse and complex physical interactions in a unified, structured form, extending beyond narrow-scoped skills like grasping to include composition of multiple affordance types. These pairs are encoded as semantic embeddings (e.g., from language or visual descriptions) that characterize the entity's properties for spatial identification.

Heatmap-Conditioned Visuomotor Control

Instead of directly combining raw RGB images with high-level user specifications, SAGA's policy operates on heatmap-informed point clouds. This approach grounds task objectives in 3D space as affordance heatmaps, which highlight task-relevant entities while abstracting away spurious appearance variations. This disentanglement of high-level semantics from low-level visuomotor control enables data-efficient and robust policy learning on multi-task robot data. The policy is instantiated as a conditional diffusion model, predicting T-step action chunks for temporal consistency.

SAGA vs. End-to-End & Modular Baselines

Feature SAGA Baselines (End-to-End/Modular)
Task Representation Structured Affordance-Entity Pairs Goal states/observations, Language (symbolic), Binary masks
Generalization Robust across novel environments, tasks, user specs Limited, brittle outside training distribution
Adaptation Zero-shot & Few-shot (heatmap tuning) Requires massive datasets, hand-engineered modules
Spatial Grounding Explicit 3D Affordance Heatmaps Implicit (black-box), less robust 2D masks/keypoints
Data Efficiency High (2 orders less data than VLAs) Low (VLAs), higher (Modular but less robust)
Behaviors Covered Diverse, complex mobile manipulation Narrowly defined (e.g., grasping, rearrangement)

Real-World Performance on Quadrupedal Manipulator

SAGA was extensively evaluated on a quadrupedal mobile manipulator across eleven real-world tasks in cluttered environments with novel objects and configurations. It consistently achieved high success rates, demonstrating strong generalization to unseen scenarios. For example, tasks composing multiple affordance types (e.g., sweeping with unseen tools) were performed robustly. The framework also supports diverse user inputs including natural language, selected points, and few-shot demonstrations, enabling both zero-shot execution and rapid adaptation.

Versatile Interfacing to User Specifications

SAGA's structured task representation acts as a unified, modality-agnostic interface. It supports language instructions (decomposed by VLM into subtasks and entity embeddings), point inputs (selected pixels on visual observations for entity embeddings), and few-shot adaptation through 'heatmap tuning'. This novel adaptation paradigm optimizes the task representation embeddings via backpropagation on a few examples, enabling fast convergence without ground truth instructions.
