A loose motor mount forces a programmer to abandon elegant work and redesign the team's debugging method.
Three days before competition, our robot developed a leftward drift. I assumed the controller needed tuning and spent an evening adjusting offsets, thresholds, and recovery logic. Each patch improved one run and damaged the next. By midnight, the program had become an elaborate argument for my first diagnosis. Ana watched the robot accelerate, then asked why I believed the failure was software. I heard the question as criticism because I had invested too much time in the answer.
We placed tape across the floor and measured turn angle at several speeds. The error appeared only under high torque. Beneath the shell, a loose motor mount tilted by a few millimeters. My code had been compensating for a screw. We tightened the bracket, restored the earlier program, and watched the robot hold its line. Deleting my fixes took seconds; admitting they had hidden the real problem took longer. I wrote the failure into our log, including the tests I should have run before editing.
The challenge was not the loose mount. It was separating loyalty to the project from loyalty to my work. Our team now lists mechanical, electrical, environmental, and software hypotheses before assigning a fix, and the person least attached to the leading explanation designs the next test. I still love elegant code, but I value it less than a method that can prove the code unnecessary. Unexpected problems will continue to expose what I assume. My response is no longer to work faster inside the assumption; it is to make the assumption visible enough for evidence and teammates to challenge it.
