Patent ID: 11059175

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 Sig1 is generated, a unit, connected to the first processor via a data link, for generating a second stop signal Sig2, which generates the second stop signal Sig2 when the unit receives the first stop signal Sig1 or 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 Sig2 is present.
