Abstract

A method is provided for operating a robotic device having a kinematic chain of movable components. The method includes: detecting respective values at least one characteristic of a plurality of the movable components by sensors arranged on the kinematic chain or in the vicinity of the kinematic chain; ascertaining a maximum value based on the detected values; comparing the ascertained maximum value with a predefined first safety limit by a controller of the robotic device; and adjusting the at least one characteristic or a further characteristic of the kinematic chain when the ascertained maximum value has a predefined relationship with the first safety limit, in order to increase the operating safety of the robotic device.
