AB - Robots have the potential to assist people with disabilities and the elderly. One of the most common and burdensome tasks for caregivers is dressing. Two challenges of robot-assisted dressing are modeling the dynamics of garments and handling visual occlusions that obstruct the perception of the full state of the garment due to the proximity between the garment, the robot, and the human. In this letter, we propose a diffusion-based dynamics model for garments during robot-assisted dressing that can deal with partial point cloud observations. The diffusion model, conditioned on the observation and the robot's action, is used to predict a full point cloud of the garment's opening of the future state. The model is utilized in a model predictive controller, that is trained iteratively with model-based reinforcement learning. In our experiments, we examine a common problem of dressing: the insertion of a garment's sleeve on an arm. As demonstrated by the performed experiments, the proposed diffusion-based model predictive controller can be effectively used for robot-assisted dressing and handle visual occlusions. Moreover, our approach is highly sample-efficient. Specifically, the controller achieved 91.2% success rate in the examined dressing task with less than 100 sampled trajectories. Real-wold experiments demonstrate that the proposed method can adapt to the sim-to-real gap and generalize well to novel garments and configurations of the body.
