Data-Efficient Representation Learning for Grasping and Manipulation
Doctoral thesis, 2026

Robotic manipulation requires models that can generalize across variations in objects, scenes, and task conditions. However, collecting large-scale datasets that capture such variations in real-world robotic settings remains costly and time-consuming, making data-efficient learning an important challenge. This thesis investigates how the choice of representation can influence data-efficient generalization in robotic grasping and manipulation. First, we introduce local shape descriptors that allow grasp poses to transfer across object categories by exploiting shared geometric structure. Second, we develop neural field models that represent scenes and motions as smooth functions of latent variables learned from demonstrations. This formulation organizes demonstrations in a structured latent space, enabling motion generation from a small number of demonstrations and generalization across scene variations through interpolation. Third, we propose a potential-function-based framework for reactive motion generation, where neural fields model smooth energy functions whose gradients generate well-behaved vector fields for control. A state dependent phase formulation further enables the representation of complex motion patterns while preserving reactivity. Together, these approaches demonstrate how representation choices can improve data efficiency and generalization in robotic grasping and manipulation.

Paper in proceeding

General-purpose robotic manipulation requires adaptability to diverse environments. To achieve this, robots need effective representations that allow them to understand their environment and perform correct actions. Machine learning provides a strong basis for designing and teaching robots such representations. While machine learning has driven remarkable progress in areas such as computer vision and natural language processing, its application to robotics is constrained by the high cost and complexity of collecting real-world training data. In robotics, collecting real-world data requires physical interaction with the environment and often involves expert-designed task setups, human demonstrations, careful supervision, and extensive data curation, making the process expensive and difficult to scale. This creates a critical need for data-efficient learning approaches. This thesis presents a framework for data-efficient robotic manipulation through structured, task-aware representations. We investigate part-based representations for transferring grasp information, scene representations that capture essential structure for motion modeling, and reactive motion models that enable adaptive execution. Collectively, these contributions demonstrate that embedding task-relevant structure into robot representations provides a foundation for teaching robots diverse manipulation skills, enabling new capabilities, and substantially improving data efficiency.
