Our Neural Network is composed of two main parts: a Multi-Layer Perceptron called Transducer and a Transformer. The former estimates, based on the kinematic data from a motion capture suit, the current contact forces. The latter predicts - taking as input the same kinematic data and the output of the Transducer - the human motions and the contact forces over a time window in the future. We validated our approach by testing the network on directions of motions that were not provided in the training set. We also compared our approach to a purely Transformer-based network, showing a better prediction accuracy of the contact forces. date: 2024-08-08 date_type: published publisher: IEEE official_url: https://doi.org/10.1109/ICRA57147.2024.10611211 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2310425 doi: 10.1109/ICRA57147.2024.10611211 isbn_13: 979-8-3503-8457-4 lyricists_name: Kanoulas, Dimitrios lyricists_id: DKANO15 actors_name: Kanoulas, Dimitrios actors_id: DKANO15 actors_role: owner full_text_status: public pres_type: paper publication: Proceedings - IEEE International Conference on Robotics and Automation place_of_pub: Yokohama, Japan pagerange: 3161-3167 event_title: 2024 IEEE International Conference on Robotics and Automation (ICRA) event_dates: 13 May 2024 - 17 May 2024 book_title: Proceedings - IEEE International Conference on Robotics and Automation citation: Fusco, A; Modugno, V; Kanoulas, D; Rizzo, A; Cognetti, M; (2024) Transformer-Based Prediction of Human Motions and Contact Forces for Physical Human-Robot Interaction.
