System and method for controlling a robot

Abstract

A system for controlling a robot. The system includes: an interface that provides data DAT(t) captured by one or more sensors, wherein the data DAT(t) indicate a current state ZUS(t) of the robot, a first processor that is connected to the interface and that is set up to use a first algorithm to check, on the basis of the data DAT(t) and a prescribed state space Z, which indicates exclusively permitted states of the robot, whether it holds that: ZUS(t)ϵZ, wherein in the event of: ZUS(t)∉Z a first stop signal Sigis generated, a unit, connected to the first processor via a data link, for generating a second stop signal Sig, which generates the second stop signal Sigwhen the unit receives the first stop signal Sigor when the unit establishes that the data link is interrupted, a second processor, connected to the interface and the first processor or only to the first processor, that is set up to use a second algorithm to check, on the basis of the data DAT(t) and a prescribed state space Z' or a boundary for the state space Z′, whether it holds that: ZUS(t)ϵZ′, wherein in the event of ZUS(t)∉Z′ the second processor prompts an interruption unit to interrupt the data link between the first processor and the unit, and a control unit, connected to the unit, for controlling the robot, which control unit controls/regulates the robot into a prescribed safe state when the second stop signal Sigis present.
