Virtual robotics refers to the use of computer software and simulations to design, program, and test robots in a virtual environment. It allows engineers and programmers to create and test robots without the need for physical prototypes, which can save time and resources. Virtual robotics can also be used for educational purposes, allowing students to learn about robotics and programming in a safe and controlled environment. Virtual robotics can be used in a variety of industries, including manufacturing, healthcare, and entertainment.
