Instead the safety of the operator has been ensured by preventive training utilizing virtual reality (VR) based training introducing the operator beforehand how to work safely in human-robot collaboration environment when heavy payload industrial robots are used. Details of this approach is described in the linked technical module “VR-BASED SAFETY TRAINING FOR HRC”
