Method for automatically planning an optimal trajectory for a robot device and robot control system for a robot device

A robot control system for automatically planning an optimal trajectory for a robot device, comprising:

• a safety controller module configured to provide at least one safety-related information comprising at least one safety zone of the robot device including at least one safety condition for a movement behavior of the robot device that is supervised by the safety controller during an operation of the robot device;
• a motion planner module connected to the safety controller module via a communication interface, wherein the motion planner module is further configured to receive at least one movement-related target parameter of the robot device that is optimized for the operation of the robot device, and wherein the motion planner module is configured to generate an optimal trajectory for the robot device by incorporating the at least one safety-related information and the movement-related target parameter;
• and
• a motion control module configured to control a movement of the robot device based on the generated optimal trajectory.

A computer program product comprising instructions which, when the computer program is executed by a computer processor, causes the computer to perform a method for automatically planning an optimal trajectory for a robot device, comprising:

• Instructions for obtaining from a safety controller module at least one safety-related information comprising at least one safety zone information of the robot device including at least one safety condition for a movement behavior of the robot device that is supervised by the safety controller during operation of the robot device;
• instructions for obtaining a movement-related target parameter of the robot device that will be optimized for an operation of the robot device;
• and
• instructions for generating by the motion planner module the optimal trajectory for the robot device by incorporating the at least one safety-related information and the movement-related target parameter, wherein the generated optimal trajectory defines an optimal movement of the robot device that respects the safety condition and the movement-related target parameter.
