Researchers have introduced LiMoDE, a novel two-stage learning scheme designed to improve lifelong robot manipulation capabilities. This approach utilizes a dynamic Mixture-of-Experts (MoE) structure during pre-training to learn reusable skills and effectively model interactions between them. A lifelong MoE adaptation mechanism is then employed to dynamically combine experts for new tasks, facilitating knowledge transfer and mitigating catastrophic forgetting. Experiments on simulated and real-world tasks demonstrate LiMoDE's effectiveness in achieving superior performance and strong lifelong adaptation with a moderate increase in trainable parameters and inference overhead.
