Sabotage in a motor screwdriving robot has revealed a rare technical vulnerability: the alteration of tightening torque through an electronic offset in the head transducer. This incident, which affected the assembly line, was analyzed using 3D tools such as GOM Inspect and Blender to reconstruct the failure sequence and determine the origin of the manipulation.

The analysis with GOM Inspect allowed scanning the head and detecting deviations in the transducer geometry, while Blender was used to simulate the robot's trajectory and the exact moment of the offset. It was identified that a falsified electronic signal modified the actual applied torque, generating insufficient or excessive tightenings. This method, difficult to detect in visual inspections, required cross-referencing data between the torque history and the 3D meshes to confirm the anomaly.
The rebellious screwdriver: when a robot decides to tighten its own way 🤖
The most curious aspect of the case is that the robot, far from being a professional saboteur, was only following orders. Someone told it: tighten loose here and tight there, and the poor mechanism, without its own judgment, did so to the letter. Now, technicians inspect every transducer as if it were a spy, and the robot awaits its turn in the interrogation room, although its only confession will be an error beep.
