CurricuLLM: Automatic Task Curricula Design for Learning Complex Robot Skills Using Large Language Models

ICRA 2025

Curriculum learning is a training mechanism in reinforcement learning (RL) that facilitates the achievement of complex policies by progressively increasing the task difficulty during training. However, designing effective curricula for a specific task often requires extensive domain knowledge and hu

DDAT: Diffusion Policies Enforcing Dynamically Admissible Robot Trajectories

RSS 2025poster

Diffusion models excel at creating images and videos thanks to their multimodal generative capabilities, which have also attracted the interest of roboticists for trajectory planning and policy learning. However, the stochastic nature of diffusion models is fundamentally at odds with the precise dyn…

Integrating Predictive Motion Uncertainties with Distributionally Robust Risk-Aware Control for Safe Robot Navigation in Crowds

ICRA 2024poster

Ensuring safe navigation in human-populated environments is crucial for autonomous mobile robots. Although recent advances in machine learning offer promising methods to predict human trajectories in crowded areas, it remains unclear how one can safely incorporate these learned models into a control…
