Imagine standing before an array of precision electronic components and assembled mechanical structures – they remain merely static hardware without life. The key to animating these components and making them perform according to your will lies in programming. Whether aspiring to build robots from scratch or seeking advancement in robotics, mastering appropriate programming languages forms the crucial foundation.

"Which programming language works best for robotics development?" This frequently asked question has no absolute answer. Different languages possess unique advantages, limitations, and applications. While C++ and Python often rank as the most popular choices in robotics, they don't suit all scenarios. The optimal selection depends on both your robotics expertise level and the specific tasks you intend your robot to perform.

A more precise question would be: "Which language should I learn to make my robot execute particular tasks?" Defining clear objectives remains paramount when selecting programming languages. Below we examine the most commonly used robotics programming languages and analyze their respective applications.

Before exploring individual programming languages, we must understand the Robot Operating System (ROS). Not a true operating system, ROS constitutes a collection of software libraries and tools for building robotic applications. Consider it the "Android system" of robotics – a framework enabling developers to construct diverse applications.

ROS primarily builds upon C++ and Python. C++ excels in high-performance computing, while Python shines in rapid development. The ROS framework combines strengths from both languages. As an open-source project with extensive community support, ROS offers thousands of optimized software packages for various functions. Its ability to connect processes from multiple devices (called nodes) to a central hub makes it invaluable for robotics development.

ROS serves as an excellent starting point for anyone learning robotics. The most effective approach involves hands-on development of actual robotic applications. With support for both C++ (through roscpp library) and Python (via rospy library), ROS lets developers leverage both languages' advantages simultaneously.

The ultimate choice depends on your robot's intended functionality. Below we detail several primary robotics programming languages and their respective applications:

C++'s popularity in robotics development stems from several advantages:

• Foundation for understanding robotic behavior logic
• Extensive compatibility with various tools, platform-specific libraries, and low-level hardware
• Real-time execution capability for complex, specialized robotic tasks

Despite its steeper learning curve, C++ represents a mature industrial standard that maximizes robotic performance, making it ideal for developers building high-performance robots.

This equally popular yet more accessible language remains favored after three decades because:

• Ease of learning makes it one of the most beginner-friendly options
• Concise efficiency enables defining robotic functions with less code in shorter time
• Strong community support with extensive documentation
• Excellent automation and post-processing capabilities
• Wide adoption in developing powerful modern robotic systems

Python's primary drawback as an interpreted language includes more challenging error detection and slower execution compared to compiled languages like C/C++. However, Python can integrate with C/C++ to run performance-intensive code without speed penalties.

Popular among both robotics engineers and educational institutions, MATLAB excels at:

• Data analysis
• Building control systems
• Modeling and simulating robotic systems

MATLAB's ability to identify errors during prototyping rather than production makes it another excellent choice for robotics beginners.

C# serves as a fundamental language for aspiring programmers entering various IT fields including robotics. Its relative ease of learning, combined with excellent UI design applications and seamless embedded system communication, enables interesting projects with Arduino and similar systems. Advanced users can connect ROS systems with game engines like Unity for industrial or commercial virtual environments.

Most robotics courses include Java as a required language because it enables robots to perform human-like activities through advanced functionality implementation.

Designed as a visual language primarily for 8-16 year olds, Scratch uses block-based programming with Squeak, ActionScript, and JavaScript components. While lacking industrial applications, it effectively prepares students for advanced robotics and programming studies.

These languages, once considered outdated, are experiencing renewed interest due to their early AI applications. Lisp (the world's second-oldest programming language) even appears in parts of ROS, while Prolog's logic programming enables AI knowledge representation, notably in IBM's Watson AI.

HDLs prove valuable for electronics engineers developing low-level robotic components, particularly in creating cost-effective, rapid-production electronic parts through Field Programmable Gate Arrays (FPGAs) without silicon chips.

As one of the first languages for industrial robot programming, Pascal remains relevant for industrial applications despite being outdated for everyday use. Various manufacturers employ proprietary languages for industrial robots, making generalized language learning challenging.

The past two decades witnessed unprecedented technological advancement globally, significantly driven by robotics' efficiency and convenience. As robotics and AI applications continue expanding across all sectors, those entering the field today will help shape a future where robots better serve humanity – whether through home automation systems, improved waste recycling solutions, or other innovations that will undoubtedly pave our collective future.
