robot was set to 20 percent of its maximum speed and that the default settings instructed the arm to turn the bolt backward twice before spinning it forward to tighten. “Factory settings are always idiotic,” he said. So he quickly rewrote the code to delete the backward turns. Then he set the speed to 100 percent capacity. That started to strip the threads, so he dialed it back to 70 percent. It worked fine and cut the time it took to bolt the cars to the skids by more than half.
