What if the cobot becomes man's best friend in Factory 4.0? Safran is anticipating this near future, to facilitate operator missions and improve working conditions on its production sites. Example in Gennevilliers (France), at Safran Aircraft Engines, where a unit specializes in the manufacture of titanium leading edges for the LEAP engine. A cobot assists operators in fitting parts. The teams, who were involved in the project upstream, tell us about this social, sustainable and technological innovation, as well as about their “new best friend”!
