Gazebo
Gazebo is a popular simulation tool that helps robotics engineers test their robots in a virtual environment before using real hardware. Think of it like a virtual testing ground where developers can safely try out robot behaviors, sensors, and movements without risking damage to expensive physical equipment. It's similar to how video game designers create virtual worlds, but for testing real robots. This tool is especially important because it saves time and money in robot development, and lets engineers find and fix problems early in the design process.
