Excavation of Fragmented Rocks with Multi-modal Model-based Reinforcement Learning

IROS 2022poster

This paper presents a multi-modal model-based reinforcement learning (MBRL) approach to the excavation of fragmented rocks, which are very challenging to model due to their highly variable sizes and geometries, and visual occlusions. A multi-modal recurrent neural network (RNN) learns the dynamics o…

Imitation Learning and Model Integrated Excavator Trajectory Planning

IROS 2022poster

Automated excavation is promising to improve the safety and efficiency of excavators, and trajectory planning is one of the most important techniques. In this paper, we propose a two-stage method that integrates data-driven imitation learning and model-based trajectory optimization to generate optim…
