Introduction of cyber-physical system in robotized press-brake line for metal industry
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-11)Bin picking is a typical work, which is easy to automate up to a given complexity of the work-piece dimensions. In case of casted work-pieces, the dimensions are most of the time not accurate enough for an industrial robot to be able to pick it up without additional sensors/intelligence. In this paper we introduce a cyber-physical system, where all sensors, actuators, machines and industrial robot ... -
