Visual imitation learning from one-shot demonstration for multi-step robot pick and place tasks

Imitation learning provides an intuitive approach for robot programming by enabling robots to learn directly from human demonstrations. While recent visual imitation learning methods have shown promise, they often depend on large datasets, which limits their applicability in manufacturing scenarios where tasks and objects are highly specialized. This paper proposes a one-shot visual imitation learning framework that allows robots to acquire multi-step pick & place tasks from a single video demonstration. The framework integrates hand detection, object detection, trajectory segmentation, and skill learning through Dynamic Movement Primitives (DMPs). Hand trajectories are mapped to the robot's end-effector, enabling the system to generalize to new object positions while significantly reducing data requirements. The approach is evaluated in simulation and achieves reliable reproduction of multi-step tasks. These results demonstrate the potential of one-shot visual imitation learning to reduce programming complexity and increase flexibility for industrial robot applications.
