Eliminating Workflow Interference in a Robotic Assembly Cell
At our client’s manufacturing site, robots frequently paused during assembly tasks due to subtle motion‑interference issues that were nearly impossible to diagnose on the physical line. The robots occasionally entered unexpected standby states, causing irregular delays and reducing overall throughput. Even experienced robot and PLC engineers struggled to identify the root cause because the interference occurred only under specific motion sequences.
Using our digital‑twin simulation and hybrid ROS‑PLC control environment, we replayed the robot’s movements and process logic repeatedly. Through detailed visualization of motion paths and process timing, we discovered that one robot’s approach trajectory intersected with another robot’s workspace by less than a few centimeters—too small to detect on-site but enough to trigger safety slowdowns.
After adjusting the motion path and updating the PLC coordination logic, the interference was completely resolved. As a result, the client eliminated unexpected pauses, stabilized cycle time, and significantly improved production efficiency.
