摘要
The invention relates to a safety device (15) comprising a bottom support (16), a transmission device (17) with a transmission antenna connection (18) that can be electrically contacted on the bottom support (16), and a signal generator (19) designed to produce an output signal with a pre-determined characteristic and to transmit same to the transmission device (17), in order to radiate the output signal via the bottom support (16). Said device also comprises an input line (20) that can be electrically coupled to the metal structure of a robot arm (2) and is designed to detect, as an input signal, the output signal radiated by the bottom support (16) via the metal structure of the robot arm (2), a receiving device (21) designed to receive the input signal detected by the input line (20), a comparison device (22) connected to the receiving device (21) and to the transmission device (17), which is designed to compare input signals detected by the receiving device (21) with the output signal transmitted by the transmission device (17), and an evaluation device (23) connected to the comparison device (22), which is designed to produce a safety signal identifying the safety state of the workstation, according to a comparison result of the comparison device (22), for transmission to a robot control system (12) of the robot (1) for implementing at least one safety function. The invention also relates to a robotic workstation comprising such a safety device (15).
