a man can do anything but a computer need an operating system to work and give it commands

Computers and robots are inorganic, so they could indeed exist. the question is whether or not computers and robots could have come about in a universe that is inorganic.
Robots are large and nanotechnology is very, very small. They are 2 different things
funny looking face and no legs

To run the robots.
Robots are controlled by computers. They can certainly process numbers and make calculations. As for understanding, that depends on what you mean by understand. Robots with speech recognition systems can understand spoken numbers subject to the limits of the system. Robots use artificial intelligence techniques to "think". Nobody knows for sure what the limits of AI may be.
Robots do not need the things people need to survive, robots have the only ability to do what they're programmed to do, and their brains are computers.
High-throughput screening
Robots are run by computers which communicate with numbers, represented by binary combinations of high and low voltages of electricity.
