Denso had 49 patents in robotics during Q4 2023. Denso Corp filed patents for a robot control system that sets limit parameter sets for restricting robot motion based on user input, with each set corresponding to a specific scene and including main and sub-parameters. The system applies these sets to control robot motion and allows for switching between them during operation, displayed on a screen for user interaction.

Application: Robot control system (Patent ID: US20230381966A1)
The patent filed by Denso Corp describes a robot control system that sets multiple limit parameter sets to restrict the motion of a robot based on user input. Each set corresponds to a specific scene and consists of a main parameter set and various sub-parameter sets. The system applies these limit parameter sets to control the robot's motion and can switch between them by adjusting the sub-parameter sets. The user input includes defining the main parameter set, sub-parameter sets, and their dependency relationship.
Furthermore, the system ensures that the user input is valid by rejecting inputs where sub-parameter sets conflict with different main parameter sets or are not dependent on the main parameter set. The main parameter set can include parameters indicating the robot's movable range or activating/deactivating limit parameters in the sub-parameter sets. Additionally, the sub-parameter sets include conditions for switching between them, and the limit parameters in both the main and sub-parameter sets relate to the same motion characteristic, with the sub-parameter sets being limited by the main parameter set.
