Information from the China National Intellectual Property Administration shows that ABB Switzerland Ltd. has filed a patent titled “Method for Automatically Planning an Optimized Trajectory for a Robot Device and Robot Control System for a Robot Device,” with publication number CN121335782A, filed in June 2023.

The patent describes a method for automatically generating optimized motion trajectories for industrial robot systems while ensuring compliance with safety constraints during operation.

According to the filing, the system first obtains safety-related information from a safety controller module. This includes safety zone data for the robot and safety conditions governing its movement behavior. These conditions are continuously monitored by the safety controller during robot operation to ensure safe execution of motion tasks.

In addition, the system collects motion-related target parameters for the robot. These parameters define optimization goals for robot operation, such as improving efficiency, precision, or performance in specific industrial tasks.

A motion planning module then combines both safety-related constraints and motion optimization parameters to generate an optimized trajectory for the robot device. The resulting trajectory defines an optimized movement path that satisfies all safety conditions while also achieving the desired performance objectives.

This technology integrates safety control and motion optimization into a unified planning framework, enabling industrial robots to operate more efficiently without compromising safety, particularly in complex and dynamic manufacturing environments.
