What is programming robots mean?

It is the process of writing commands for a robot which will influence its future actions.

Additional InformationRobotic devices are typically controlled by one or more microcontrollers. Microcontrollers are basically little computers, with Read Only Memory (ROM) and processor in a single package.

The output of the microcontroller operates the servos and other devices of the robotic device.

So basically, when you program a robot, you're just telling the microcontroller how to perform the functions that make the robot do its work.
