What is the purpose of a 'robot simulation tool'?

The purpose of a robot simulation tool is to visualize and test robot behaviors and tasks in a digital environment. This tool allows users to create a virtual model of the robot and its operating environment, enabling them to simulate various tasks and movements before implementing them on the actual robotic system. By utilizing simulation software, engineers and operators can observe how the robot will perform specific tasks, identify potential issues, and refine their programming without the risks and costs associated with real-world testing. The ability to visualize actions in a controlled virtual setting enhances the understanding of the robot's capabilities and limitations.

The other choices may relate to aspects of robotics but do not specifically capture the main function of a simulation tool. For instance, while calculating energy consumption, assisting in physical setup, and reducing programming complexity are important in robotics, they do not encompass the primary role of visualization and testing in a simulated environment.
