Abstract

A robot system is disclosed which includes at least two robots, each having a related processing unit. The processing units are connected to each other via a network bus for data transmission, and distributed sensors are provided for gathering first and/or second measurement data within a local extension of the robot system. First measurement data gathered by at least one first sensor are transmissible to at least one processing unit related thereto. Second measurement data gathered by at least one second sensor are feedable into the network bus and provided to the at least two processing units connected thereto. The processing units can analyze the second measurement data as a variable dynamic share of workload for feeding result-data of the analysis into the network bus.

Dependent claims

Robot system comprising:

at least two robots;
at least two processing units, the processing units being connected to each other via a network bus for data transmission and each being related to a respective robot of the at least two robots;
and
distributed sensor means for gathering first and/or second measurement data within a local extension of the robot system, the first measurement data gathered by at least one first sensor means being transmissible to at least one of the processing of the at least two processing units that is related thereto, and second measurement data gathered by at least one second sensor means being feedable into the network bus and provided to the at least two processing units connected thereto for analyzing the second measurement data as a variable dynamic share of processing unit workload, the at least two processing units being configured to feed analysis result-data into the network bus;
wherein the first measurement data are data to be analyzed in less than a predetermined length of time and the second measurement data are data to be analyzed in greater than the predetermined length of time.
