Free robotics is a way for people to use robots or machines that run by computer code to do tasks for free. It usually involves programming the robots with a language that a computer can understand. The robots can then be used to do things like move objects, pick things up, and even do work like painting and other tasks. By using this kind of technology, people don't have to spend money to build and maintain things like factories or automated machines. Instead, they can just program the robots to do the job for them.
