Which control system response occurs when a robotic weld seam tracker's sensor fails to capture the weld joint?

💡 Explanation

The welding head deviates because the path planning relies on sensor feedback; the Inverse Kinematics calculation uses this positioning data. Therefore, the welding head will stray from the seam, rather than encode resolution decreasing which would need an encoder failure.
