The investigation concluded that workers were not sufficiently familiar with the machines and the machines were not sufficiently regulated. The robot that killed Urada was removed from the Akashi plant, and man-high fences were erected around the other two robots in the plant in the wake of the accident.
The incident led to a review of the situation, which revealed that workers lacked sufficient knowledge about the machinery and inadequate regulations were in place. As a result, the robot responsible for Urada's death was taken out of commission at the Akashi plant, and elevated barriers were erected around the other two robots to prevent similar accidents from occurring.
