This paper investigates how software robots, also known as softbots, can support the Operator 4.0 in smart factory environments, helping in the interfacing between smart machines and computer information systems with the aims of supporting the Operator 4.0 in different tasks at the shop floor. The work uses a reference framework called ARISA, which allows the derivation of softbots for given domains. An experimental setup and its results are presented in a testing scenario of a softbot to support the Operator 4.0 concept.
