CAD is one of the most useful tools in robotics, as it gives you a way to visualize your processes and experiments. It allows users to create precise and detailed digital models of robotic components and systems before they are physically built. This precision is essential in robotics, where even minor inaccuracies can lead to significant issues in performance and functionality. It also allows for rapid prototyping, where changes can be made to the design quickly and easily without the need for physical modifications. This ability to create, test, and refine robotic systems in a virtual environment makes CAD an essential tool in the field of robotics.
