Mechanical and control design solutions are intensively investigated to achieve a high performance human-robot collaboration (e.g., transparency, ergonomics, safety, etc.). However, the most of the investigated solutions involve high-cost hardware, complex design solutions and standard actuation. Moreover, state-of-the-art empowering controllers do not allow for online assistance regulation and do not embed advanced safety rules. In the presented work, an industrial exoskeleton with high payload ratio for lifting and transportation of heavy parts is proposed. A low-cost mechanical design solution is described, exploiting compliant actuation at the shoulder joint to increase safety in human-robot cooperation. A hierarchic model-based controller with embedded safety rules is then proposed (including the modeling of the compliant actuator) to actively assist the human while executing the task. An inner optimal controller is proposed for trajectory tracking, while an outer safety-based fuzzy logic controller is proposed to online deform the task trajectory on the basis of the human\u2019s intention of motion. A gain scheduler is also designed to calculate the inner optimal control gains on the basis of the performed trajectory. Simulations have been performed in order to validate the performance of the proposed device, showing promising results. The prototype is under realization.<\/jats:p>","DOI":"10.3390\/robotics8030065","type":"journal-article","created":{"date-parts":[[2019,8,2]],"date-time":"2019-08-02T15:58:16Z","timestamp":1564761496000},"page":"65","source":"Crossref","is-referenced-by-count":24,"title":["Mechanical and Control Design of an Industrial Exoskeleton for Advanced Human Empowering in Heavy Parts Manipulation Tasks"],"prefix":"10.3390","volume":"8","author":[{"given":"Alessandro","family":"Mauri","sequence":"first","affiliation":[{"name":"Consiglio Nazionale delle Ricerche (CNR), Istituto di Sistemi e Tecnologie Industriali per il Manifatturiero Avanzato (STIIMA), 20133 Milano, Italy"},{"name":"Department of Mechanical Engineering, Politecnico di Milano, 20156 Milano, Italy"}]},{"given":"Jacopo","family":"Lettori","sequence":"additional","affiliation":[{"name":"Consiglio Nazionale delle Ricerche (CNR), Istituto di Sistemi e Tecnologie Industriali per il Manifatturiero Avanzato (STIIMA), 20133 Milano, Italy"},{"name":"Department of Mechanical and Industrial Engineering, University of Brescia, 25121 Brescia, Italy"}]},{"given":"Giovanni","family":"Fusi","sequence":"additional","affiliation":[{"name":"Polibrixia, 25123 Brescia, Italy"}]},{"given":"Davide","family":"Fausti","sequence":"additional","affiliation":[{"name":"Polibrixia, 25123 Brescia, Italy"}]},{"given":"Maurizio","family":"Mor","sequence":"additional","affiliation":[{"name":"Polibrixia, 25123 Brescia, Italy"}]},{"given":"Francesco","family":"Braghin","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Politecnico di Milano, 20156 Milano, Italy"}]},{"given":"Giovanni","family":"Legnani","sequence":"additional","affiliation":[{"name":"Consiglio Nazionale delle Ricerche (CNR), Istituto di Sistemi e Tecnologie Industriali per il Manifatturiero Avanzato (STIIMA), 20133 Milano, Italy"},{"name":"Department of Mechanical and Industrial Engineering, University of Brescia, 25121 Brescia, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4427-536X","authenticated-orcid":false,"given":"Loris","family":"Roveda","sequence":"additional","affiliation":[{"name":"Consiglio Nazionale delle Ricerche (CNR), Istituto di Sistemi e Tecnologie Industriali per il Manifatturiero Avanzato (STIIMA), 20133 Milano, Italy"},{"name":"Istituto Dalle Molle di Studi sull\u2019Intelligenza Artificiale (IDSIA), Scuola Universitaria Professionale della Svizzera Italiana (SUPSI), Universit\u00e0 della Svizzera Italiana (USI), IDSIA-SUPSI, 6928 Manno, Switzerland"}]}],"member":"1968","published-online":{"date-parts":[[2019,8,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Pons, J., Rocon, E., Ruiz, A., and Moreno, J.
