Two main programming languages are the best when used in robotics: C++ and Python, often used together as each one has pros and cons. C++ is used in control loops, image processing and to interface low-level hardware. Python is used to handle high-level behaviors and to quickly develop tests or proof of concepts.

To program robot movement, you need to communicate with the robot's hardware, such as motors, sensors, and actuators, and send commands that tell the robot what to do. Python can be used to program robot movement by using various libraries and modules that provide a high-level interface to the robot's hardware.

The most popular language in robotics is probably C/C++ (C++ is an object-oriented successor to the C language). Python is also very popular due to its use in machine learning and also because it can be used to develop ROS packages – see below.

You can program robots with C++ by using robotics libraries and frameworks like ROS (Robot Operating System) or by directly interfacing with hardware using C++ code for robot control.
