X-ray of Robot Programming Language: The Spine of Modern Robotics

The need for control and guidance mechanisms has, in fact, enabled the development of robot programming languages that instruct the robot on what to do. The languages have served as the backbone on which the robots can associate with the environment, process information, and carry out tasks with precision. This blog presents a discussion of levels, methods, and applications, in relation to fundamental concepts involved in robotics programming language.

What Is Robot Programming?

Programming in robots means writing a set of instructions to be followed by the robot. These instructions will guide it to act and perform according to one's will and define its response to different inputs from the environment. This nature of programming a robot can range from simple commands of controlling basic movements to complex algorithms that enable autonomous decision-making and advanced interactions.

Types of Robot Programming

There exist various methods for robot programming, with their specific applications and levels of complexity. There are the following:

Manual Programming:

Manual programming implies physical guidance of the robot through a pre-defined sequence of motions. This has been done in simple industrial tasks, for example, welding or painting, where the robot simply repeats exactly the same motion.

Teach Pendant Programming:

Here, the robot is controlled and programmed manually using a handheld device called a teach pendant. It can be done by manually guiding the robot through desired actions and, subsequently, recording and executing them autonomously. Teach pendant programming finds its application in industrial robots, such as FANUC and ABB.

It means programming the robot in a virtual environment using particular software. The program is then transferred to the robot, which executes the instructions accordingly. This method, for complicated tasks, is rather effective and saves quite a lot of production time by reducing downtimes.

Graphical Programming:

Graphical programming, in general, is a way of programming using visually manipulated elements, such as blocks or flowcharts. It is quite intuitive and, for that reason, it constitutes the usual way to introduce students to the basic concepts of programming in educational robotics.

Many robotics programming languages have their strong points and ideal applications:

1. Python:

Python enjoys wide usage in robotics due to its simplicity and extensive number of libraries. It is the best for novices, which can develop a prototype with ease; it can also be used to control Robot Operating Systems (ROS).

2. C/C++:

When it comes to performance-critical robotics applications, the most spoken languages are C and C++. Both languages have fine control over hardware and are consequently utilized in an embedded operating system.

3. Java:

Java robot programming is in wide practice in educational robotics, among many fields, in the development of cross-platform applications. It was first characterized for its portability, featuring extensive libraries which make it suitable for a great number of robotic applications.

4. LISP:

LISP is applied in AI-based robotics during tasks that require complex data processing and symbolic computation.

5. MATLAB:

It is normally utilized in robotics in areas such as data analysis, simulation, and algorithm development. For general robotics research and in developing control systems, MATLAB proves very useful.

6. Fanuc Robot Programming:

Fanuc robots use their own specific language for programming. Further, a teaching pendant is available with which programming in KAREL becomes easy. The detailed programming of these all-purpose industrially deployed robots is given in the PDF of the Fanuc robot programming manual.

7. ABB Robot Programming:

ABB robots are programmed in a language called RAPID. Like FANUC, ABB robots are quite common in industry, and the RAPID language is designed to be both relatively easy to learn and very powerful.

Programming a Robot

How one learns to program a robot naturally depends on the type of robot and the way it is programmed. Here is the general process for programming a robot: 

1. Understand the Task

The first thing before programming is to understand the task that the robot needs to perform. This includes the objectives of the robot, its operating environment, and the input required for processing.

2. Selection of Programming Language:

Picking up the appropriate programming language will be a priority. For example, Python could be the best for rapid prototyping and teaching, while C++ would be optimal for real-time control and computation-intense tasks.

3. Setting Up the Development Environment:

Install necessary software and tools which are required for programming robots. This could be an IDE, simulators, and libraries specific to the robot type being programmed.

4. Writing the Code:

First of all, write simple programs to control the basic movements. Then, in a step-by-step process, integrate sensors, input processing, and decision algorithms into the program.

5. Test and Debug:

Testing is the inevitable part of programming the robot. First of all, test the program in a simulated virtual environment and then deploy it to the actual robot. If any bugs arise, debug those to ensure that the robot behaves in an expected fashion.

6. Deploy and Monitor:

When tested, deploy the program on the robot. Observe real-world performance, refining as necessary for optimal operation.

Schools Offering Robotics Programming Languages and Courses 

As robotics grows, many schools integrate courses in robotic programming. These courses will range in difficulty from basic programming to advanced robotics and AI.

1. University Programs:

University courses provide the student with degrees in robotics engineering, where they learn the design, programming, and application of robots. These could involve several languages of programming and hands-on experience with several types of robots.

2. Online Courses:

Courses on Coursera, edX, and Udacity range regarding robotics programming languages, starting from a very beginner level.

3. Workshops and Bootcamps:

Short-term workshops and boot camps give power training on specific aspects of robotics programming languages, such as ROS  or on specific programming languages, like Python and C++.

FANUC and ABB Robot Programming

FANUC and ABB are two leading manufacturers of industrial robots. Both firms have developed their own programming languages to control their robots.

1. FANUC Robot Programming:

FANUC robots are programmed in a language called KAREL, similar to Pascal. Additionally, FANUC provides a teaching pendant that allows operators to program robots manually. The PDF of the Fanuc robot programming manual is of great help for learning specific details related to programming in FANUC robots.

2. ABB Programming of Robots:

The programming language used by the ABB robots is RAPID. It is a simple but powerful language; it allows complicated tasks to be programmed effectively and in a straightforward manner. It finds extensive application in industries like automobile manufacture for its precision and reliability.

Pre-Programmed Robots

The pre-programmed robot has built-in instructions on how to undertake a particular task and hence does not require custom programming. Most of these robots find applications in such scenarios as assembly lines, carrying out the same task repeatedly 

1. Advantages:

Pre-programmed robots are so easy to deploy and require minimum setup. Therefore, they find much application in accomplishing repetitive tasks in manufacturing industries.

2. Limitations:

The big limitation of pre-programmed robots is that they are inelastic. They cannot adapt to a new task but through re-programming; hence, they cannot be as versatile as robots that have dynamic programming.

Java Robot Programming

Java is an integrated, versatile, and object-oriented programming language in which the greater use is found in robotics, especially in educational sectors and cross-platform applications. Java is ideal for a robotics programming language owing to its object-oriented structure and vast libraries.

1. Educational Robotics:

Java is used by several educational robotics kits due to simplicity and portability, making it a good learning tool for students.

2. Cross-Platform Applications:

In Java, the "write once, run anywhere" philosophy is very applicable for robotics because programs developed in this language must run on different hardware types without changing the programs.

How to make robot programming:

Everything from an understanding of the hardware of the robot to its actual writing and testing needs to be considered while creating a robot program. Here goes a general guide that may help do such development:

1. Define the Robot's Capabilities:

Knowing your robot's sensors, actuators, and processing power is very key to writing any effective program.

2. Select a Programming Language:

 The best language to select depends on the task at hand. Python will be good to go for rapid development, while for real-time applications, C++ might be more appropriate.

3. Program It:

Begin with the simple stuff, like locomotion, then introduce more and more complexity through sensor data integration and decision-making algorithms.

4. Simulate and Test:

First, test the program in a controlled environment using simulators, then deploy it to the robot.

5. Deploy and Optimize:

After deployment, monitor the performance of the robot, making any adjustments required for perfect operation.

Conclusion

The robot programming languages make these robots perform tasks of diverse nature-from simple actions to complicated interactions with the environment. Be it rapid prototyping in Python, performance-intensive tasks in C++, or even custom language forms like KAREL from FANUC and RAPID from ABB, there's a host of items to learn from in this realm of robotics programming language.
