What must all robots ensure according to safety regulations?

All robots must ensure they are safe according to safety regulations because the primary goal of safety regulations is to protect participants, spectators, and game officials from potential harm during competitions. Safety encompasses a variety of aspects, including the structural integrity of the robot, the way it interacts with other robots, and how it operates in the competition environment. By prioritizing safety, robots can prevent accidents and ensure that all participants can engage in the competition without unnecessary risk. The other choices, while potentially appealing in certain contexts, do not align with the fundamental requirements established by safety regulations, which are focused on preventing injuries and ensuring a secure competition for everyone involved.
