Abstract:
Human-Robot collaboration (HRC) plays a critical role in enhancing productivity and safety across various industries. While reactive motion re-planning strategies have proven useful, there is a pressing need for proactive control involving computing human intentions to enable efficient collaboration. This work addresses this challenge by proposing a deep learning-based approach for forecasting human hand trajectories and a heuristic optimization algorithm for proactive robotic task sequencing problem optimization. This work presents a human hand trajectory forecasting deep learning model that achieves state-of-the-art performance on the Ego4D Future Hand Prediction benchmark in all evaluation metrics. In addition, this work presents a problem formulation and a Dynamic Variable Neighborhood Search (DynamicVNS) heuristic optimization algorithm enabling robot to pre-plan their task sequence to avoid human hands. The proposed algorithm exhibits significant computational improvements over
the generalized VNS approach. The final framework efficiently incorporates predictions made by the deep learning model into the task sequencer, which is evaluated in an experimental setup for the HRC use-case of the UR10e robot in a visual inspection task. The results indicate the effectiveness and practicality of the proposed approach, showcasing its potential to improve human-robot collaboration in various industrial settings.
