This paper presents a unified teleoperation framework for heterogeneous master–slave robotic systems, integrating geometric mapping with learning-based temporal modeling to enable skillful and adaptive manipulation. To address structural asymmetry and dynamic task variability, the proposed framework introduces four key components. (1) A DHTₓLSTM-based temporal modeling framework is proposed to enable context-aware skill prediction from multi-source sequential data, supporting autoregressive reproduction and long-horizon manipulation. (2) A unified master–slave mapping scheme is established by combining task-space pose alignment and joint-space transformation, enabling skill transfer across structurally asymmetric systems. (3) A unit dual quaternion-based joint-space mapping algorithm is introduced to ensure consistent directional transfer between mismatched human and robot joints, preserving motion semantics. (4) A dynamic hybrid control strategy is designed to switch between geometric mapping and learning-based prediction based on task phase, enabling seamless transition from gross to fine manipulation. Experimental results demonstrate that the proposed framework achieves high spatial fidelity, robust temporal generalization, and autonomous transition capabilities, laying a solid foundation for intelligent human–robot collaboration in complex manipulation tasks.
