A
robot safety
system configured to protect humans in the vicinity of a working
robot (1, 11, 21, 31) against harmful impacts by said
robot (1, 11, 21, 31), said safety
system comprising a
sensor system (3, 13, 23) and a safety controller (4, 14, 24) configured to establish an
impact risk profile of the robot (1, 11, 21, 31) and deliver an operating
signal to a
robot controller (2, 12, 22) based on said
impact risk profile, wherein the safety controller (4, 14, 24) is configured to establish the
impact risk profile based on stored data and input signals, and that the stored data and input signals comprise stored impact data, stored data related to the path of the robot (1, 11, 21, 31), and signals from the
sensor system of events in the vicinity of the robot (1, 11, 21, 31), such as a detected human (P1, P11, P21, P22, P31, P32) in the vicinity of the robot (1, 11, 21, 31).
