What programming language is best for robotics?
Top 10 Popular Programming Languages in Robotics
There are over 1500 programming languages in the world, which is far too many to learn. Here are the ten most popular programming languages in robotics at the moment. If your favorite language isn’t on the list, please tell everyone about it in the comments! Each language has different advantages for robotics. The way I have ordered them is only partly in order of importance from least to most valuable.
10. BASIC / Pascal
BASIC and Pascal were two of the first programming languages that I ever learned. However, that's not why I've included them here. They are the basis for several of the industrial robot languages, described below. BASIC was designed for beginners (it stands for Beginners All-Purpose Symbolic Instruction Code), which makes it a pretty simple language to start with. Pascal was designed to encourage good programming practices and also introduces constructs like pointers, which makes it a good “stepping stone” from BASIC to a more involved language. These days, both languages are a bit outdated to be good for “everyday use”. However, it can be useful to learn them if you're going to be doing a lot of low level coding or you want to become familiar with other industrial robot languages.
9. Industrial Robot Languages
Almost every robot manufacturer has developed their own proprietary robot programming language, which has been one of the problems in industrial robotics. You can become familiar with several of them by learning Pascal. However, you are still going to have to learn a new language every time you start using a new robot.
ABB has its RAPID programming language. Kuka has KRL (Kuka Robot Language). Comau uses PDL2, Yaskawa uses INFORM and Kawasaki uses AS. Then, Fanuc robots use Karel, Stäubli robots use VAL3 and Universal Robots use URScript.
8. LISP
LISP is the world's second oldest programming language (FORTRAN is older, but only by one year). It is not as widely used as many of the other programming languages on this list; however, it is still quite important within Artificial Intelligence programming. Parts of ROS are written in LISP, although you don't need to know it to use ROS.
7. Hardware Description Languages (HDLs)
Hardware Description Languages are basically a programming way of describing electronics. These languages are quite familiar to some roboticists, because they are used to program Field Programmable Gate Arrays (FPGAs). FPGAs allow you to develop electronic hardware without having to actually produce a silicon chip, which makes them a quicker and easier option for some development. If you don't prototype electronics, you may never use HDLs. Even so, it is important to know that they exist, as they are quite different from other programming languages. For one thing, all operations are carried out in parallel, rather than sequentially as with processor based languages.
6. Assembly
Assembly allows you to program at "the level of ones and zeros”. This is programming at the lowest level (more or less). In the recent past, most low level electronics required programming in Assembly. With the rise of Arduino and other such microcontrollers, you can now program easily at this level using C/C++, which means that Assembly is probably going to become less necessary for most roboticists.
5. MATLAB
MATLAB, and its open source relatives, such as Octave, is very popular with some robotic engineers for analyzing data and developing control systems. There is also a very popular Robotics Toolbox for MATLAB. I know people who have developed entire robotics systems using MATLAB alone. If you want to analyze data, produce advanced graphs or implement control systems, you will probably want to learn MATLAB.
4. C#/.NET
C# is a proprietary programming language provided by Microsoft. I include C#/.NET here largely because of the Microsoft Robotics Developer Studio, which uses it as its primary language. If you are going to use this system, you're probably going to have to use C#. However, learning C/C++ first might be a good option for long term development of your coding skills.
3. Java
As an electronics engineer, I am always surprised that some computer science degrees teach Java to students as their first programming language. Java "hides" the underlying memory functionality from the programmer, which makes it easier to program than, say, C, but also this means that you have less of an understanding of what it's actually doing with your code. If you come to robotics from a computer science background (and many people do, especially in research) you will probably already have learned Java. Like C# and MATLAB, Java is an interpretive language, which means that it is not compiled into machine code. Rather, the Java Virtual Machine interprets the instructions at runtime. The theory for using Java is that you can use the same code on many different machines, thanks to the Java Virtual Machine. In practice, this doesn't always work out and can sometimes cause code to run slowly. However, Java is quite popular in some parts of robotics, so you might need it.
2. Python
There has been a huge resurgence of Python in recent years especially in robotics. One of the reasons for this is probably that Python (and C++) are the two main programming languages found in ROS. Like Java, it is an interpretive language. Unlike Java, the prime focus of the language is ease of use. Many people agree that it achieves this very well. Python dispenses with a lot of the usual things which take up time in programming, such as defining and casting variable types. Also, there are a huge number of free libraries for it, which means you don't have to "reinvent the wheel" when you need to implement some basic functionality. And since it allows simple bindings with C/C++ code, this means that performance heavy parts of the code can be implemented in these languages to avoid performance loss. As more electronics start to support Python "out-of-the-box" (as with Raspberry Pi), we are likely to see a lot more Python in robotics.
1. C/C++
Finally, we reach the Number 1 programming language in robotics! Many people agree that C and C++ are a good starting point for new roboticists. Why? Because a lot of hardware libraries use these languages. They allow interaction with low level hardware, allow for real time performance and are very mature programming languages. These days, you'll probably use C++ more than C, because the language has much more functionality. C++ is basically an extension of C. It can be useful to learn at least a little bit of C first, so that you can recognize it when you find a hardware library written in C. C/C++ are not as simple to use as, say, Python or MATLAB. It can take quite a lot longer to implement the same functionality using C and it will require many more lines of code. However, as robotics is very dependent on real time performance, C and C++ are probably the closest thing that we roboticists have to "a standard language".
In Which Order Should You Learn Them?
Just because I've listed these ten doesn't mean that you have to learn all of them, or indeed any of them. The most important thing is to find a language that feels natural for you and fits with your robotic hardware. You want a language which allows you to develop programs quickly and easily, so that you can focus more on developing functionality. For this reason, I would recommend learning Python first. This is just my own personal opinion. If another language makes more sense for you, then learn that instead. However, Python is an amazingly straightforward language to learn and hugely powerful thanks to the many, easily accessible libraries. I have heard many accounts from (already experienced) programmers who learned Python in a couple of days and were immediately converted to it for almost all of their programming needs. As one guy said, "I can produce usable code in Python as fast as I can type". After you've gotten reasonably proficient using Python, I would personally recommend learning C, followed by C++. You will need it to interface with a huge majority of robotic hardware drivers.
THANK YOU.

What is ARDUINO?
Arduino is an open-source hardware and software company, project and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices and interactive objects that can sense and control both physically and digitally. Its products are licensed under the GNU Lesser General Public License (LGPL) or the GNU General Public License (GPL), permitting the manufacture of Arduino boards and software distribution by anyone. Arduino boards are available commercially in preassembled form or as do-it-yourself (DIY) kits.
Arduino board designs use a variety of microprocessors and controllers. The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards or breadboards (shields) and other circuits. The boards feature serial communications interfaces, including Universal Serial Bus (USB) on some models, which are also used for loading programs from personal computers. The microcontrollers are typically programmed using a dialect of features from the programming languages C and C++. In addition to using traditional compiler toolchains, the Arduino project provides an integrated development environment (IDE) based on the Processing language project.
The Arduino project started in 2003 as a program for students at the Interaction Design Institute Ivrea in Ivrea, Italy, aiming to provide a low-cost and easy way for novices and professionals to create devices that interact with their environment using sensors and actuators. Common examples of such devices intended for beginner hobbyists include simple robots, thermostats and motion detectors.
The name Arduino comes from a bar in Ivrea, Italy, where some of the founders of the project used to meet. The bar was named after Arduin of Ivrea, who was the margrave of the March of Ivrea and King of Italy from 1002 to 1014.
DEVELOPER: ARDUINO.CC
What is RASPBERRY PI?
The Raspberry Pi is a series of small single-board computers developed in the United Kingdom by the Raspberry Pi Foundation to promote the teaching of basic computer science in schools and in developing countries.The original model became far more popular than anticipated, selling outside its target market for uses such as robotics. It does not include peripherals (such as keyboards and mice) and cases. However, some accessories have been included in several official and unofficial bundles.
The organization behind the Raspberry Pi consists of two arms. The first two models were developed by the Raspberry Pi Foundation. After the Pi Model B was released, the Foundation set up Raspberry Pi Trading, with Eben Upton as CEO, to develop the third model, the B+. Raspberry Pi Trading is responsible for developing the technology while the Foundation is an educational charity to promote the teaching of basic computer science in schools and in developing countries.
According to the Raspberry Pi Foundation, more than 5 million Raspberry Pis were sold by February 2015, making it the best-selling British computer. By November 2016 they had sold 11 million units, and 12.5m by March 2017, making it the third best-selling "general purpose computer". In July 2017, sales reached nearly 15 million. In March 2018, sales reached 19 million.
Hardware
The Raspberry Pi hardware has evolved through several versions that feature variations in memory capacity and peripheral device support.
This block diagram describes Model B and B+; Model A, A+, and the Pi Zero are similar but lack the Ethernet and USB hub components. The Ethernet adapter is internally connected to an additional USB port. In Model A, A+, and the Pi Zero, the USB port is connected directly to the system on a chip (SoC).
On the Pi 1 Model B+ and later models, the USB/Ethernet chip contains a five-port USB hub, of which four ports are available, while the Pi 1 Model B only provides two. On the Pi Zero, the USB port is also connected directly to the SoC, but it uses a micro USB (OTG) port.
Robotics Programming
Robot software is the set of coded commands or instructions that tell a mechanical device and electronic system, known together as a robot, what tasks to perform. Robot software is used to perform autonomous tasks. Many software systems and frameworks have been proposed to make programming robots easier.

what is robotics ?
Robotics is an interdisciplinary branch of engineering and science that includes mechanical engineering, electronic engineering, information engineering, computer science, and others. Robotics deals with the design, construction, operation, and use of robots, as well as computer systems for their control, sensory feedback, and information processing.
The concept of creating machines that can operate autonomously dates back to classical times, but research into the functionality and potential uses of robots did not grow substantially until the 20th century. Throughout history, it has been frequently assumed by various scholars, inventors, engineers, and technicians that robots will one day be able to mimic human behavior and manage tasks in a human-like fashion. Today, robotics is a rapidly growing field, as technological advances continue; researching, designing, and building new robots serve various practical purposes, whether domestically, commercially, or militarily. Many robots are built to do jobs that are hazardous to people such as defusing bombs, finding survivors in unstable ruins, and exploring mines and shipwrecks. Robotics is also used in STEM (science, technology, engineering, and mathematics) as a teaching aid.
Robotics is a branch of engineering that involves the conception, design, manufacture, and operation of robots. This field overlaps with electronics, computer science, artificial intelligence, mechatronics, nanotechnology, and bioengineering.
Components of Robotics: -
Power source
At present, mostly (lead–acid) batteries are used as a power source. Many different types of batteries can be used as a power source for robots. They range from lead-acid batteries, which are safe and have relatively long shelf lives but are rather heavy compared to silver-cadmium batteries that are much smaller in volume and are currently much more expensive. Designing a battery-powered robot needs to take into account factors such as safety, cycle lifetime and weight. Generators, often some type of internal combustion engine, can also be used. However, such designs are often mechanically complex and need fuel, require heat dissipation and are relatively heavy. A tether connecting the robot to a power supply would remove the power supply from the robot entirely. This has the advantage of saving weight and space by moving all power generation and storage components elsewhere. However, this design does come with the drawback of constantly having a cable connected to the robot, which can be difficult to manage.[32] Potential power sources could be:
- pneumatic (compressed gases)
- Solar power (using the sun's energy and converting it into electrical power)
- hydraulics (liquids)
- flywheel energy storage
- organic garbage (through anaerobic digestion)
- nuclear
Actuation
Actuators are the "muscles" of a robot, the parts which convert stored energy into movement. By far the most popular actuators are electric motors that rotate a wheel or gear, and linear actuators that control industrial robots in factories. There are some recent advances in alternative types of actuators, powered by electricity, chemicals, or compressed air.
Electric motors
The vast majority of robots use electric motors, often brushed and brushless DC motors in portable robots or AC motors in industrial robots and CNC machines. These motors are often preferred in systems with lighter loads, and where the predominant form of motion is rotational.
Linear actuators
Various types of linear actuators move in and out instead of by spinning, and often have quicker direction changes, particularly when very large forces are needed such as with industrial robotics. They are typically powered by compressed and oxidized air (pneumatic actuator) or an oil (hydraulic actuator).
Series elastic actuators
A flexure is designed as part of the motor actuator, to improve safety and provide robust force control, energy efficiency, shock absorption (mechanical filtering) while reducing excessive wear on the transmission and other mechanical components. The resultant lower reflected inertia can improve safety when a robot is interacting with humans or during collisions. It has been used in various robots, particularly advanced manufacturing robots and[33] walking humanoid robots.
Air muscles
Pneumatic artificial muscles, also known as air muscles, are special tubes that expand(typically up to 40%) when the air is forced inside them. They are used in some robot applications.
Muscle wire
Muscle wire, also known as shape memory alloy, Nitinol® or Flexinol® wire, is a material which contracts (under 5%) when electricity is applied. They have been used for some small robot applications.
Electroactive polymers
EAPs or EPAMs are a plastic material that can contract substantially (up to 380% activation strain) from electricity, and have been used in facial muscles and arms of humanoid robots,[40] and to enable new robots to float, fly, swim or walk.
Piezo motors
Recent alternatives to DC motors are piezo motors or ultrasonic motors. These work on a fundamentally different principle, whereby tiny piezoceramic elements, vibrating many thousands of times per second, cause linear or rotary motion. There are different mechanisms of operation; one type uses the vibration of the piezo elements to step the motor in a circle or a straight line.[Another type uses the piezo elements to cause a nut to vibrate or to drive a screw. The advantages of these motors are nanometer resolution, speed, and available force for their size. These motors are already available commercially, and being used on some robots.
Elastic nanotubes
Elastic nanotubes are promising artificial muscle technology in early-stage experimental development. The absence of defects in carbon nanotubes enables these filaments to deform elastically by several percents, with energy storage levels of perhaps 10 J/cm3 for metal nanotubes. Human biceps could be replaced with an 8 mm diameter wire of this material. Such compact "muscle" might allow future robots to outrun and outjump humans.[47]
Sensing
Sensors allow robots to receive information about a certain measurement of the environment, or internal components. This is essential for robots to perform their tasks, and act upon any changes in the environment to calculate the appropriate response. They are used for various forms of measurements, to give the robots warnings about safety or malfunctions, and to provide real-time information of the task it is performing.
Touch
Current robotic and prosthetic hands receive far less tactile information than the human hand. Recent research has developed a tactile sensor array that mimics the mechanical properties and touches receptors of human fingertips.[48][49] The sensor array is constructed as a rigid core surrounded by conductive fluid contained by an elastomeric skin. Electrodes are mounted on the surface of the rigid core and are connected to an impedance-measuring device within the core. When the artificial skin touches an object the fluid path around the electrodes is deformed, producing impedance changes that map the forces received from the object. The researchers expect that an important function of such artificial fingertips will be adjusting robotic grip on held objects.
Scientists from several European countries and Israel developed a prosthetic hand in 2009, called SmartHand, which functions like a real one—allowing patients to write with it, type on a keyboard, play piano and perform other fine movements. The prosthesis has sensors which enable the patient to sense real feeling in its fingertips.
Vision
Computer vision is the science and technology of machines that see. As a scientific discipline, computer vision is concerned with the theory behind artificial systems that extract information from images. The image data can take many forms, such as video sequences and views from cameras.
In most practical computer vision applications, the computers are pre-programmed to solve a particular task, but methods based on learning are now becoming increasingly common.
Computer vision systems rely on image sensors which detect electromagnetic radiation which is typically in the form of either visible light or infra-red light. The sensors are designed using solid-state physics. The process by which light propagates and reflects off surfaces is explained using optics. Sophisticated image sensors even require quantum mechanics to provide a complete understanding of the image formation process. Robots can also be equipped with multiple vision sensors to be better able to compute the sense of depth in the environment. Like human eyes, robots' "eyes" must also be able to focus on a particular area of interest, and also adjust to variations in light intensities.
There is a subfield within computer vision where artificial systems are designed to mimic the processing and behavior of the biological system, at different levels of complexity. Also, some of the learning-based methods developed within computer vision have their background in biology.
Other
Manipulation
Robots need to manipulate objects; pick up, modify, destroy, or otherwise have an effect. Thus the "hands" of a robot are often referred to as end effectors,[52] while the "arm" is referred to as a manipulator.[53] Most robot arms have replaceable effectors, each allowing them to perform some small range of tasks. Some have a fixed manipulator which cannot be replaced, while a few have one very general purpose manipulator, for example, a humanoid hand.[54] Learning how to manipulate a robot often requires a close feedback between human to the robot, although there are several methods for remote manipulation of robots.[55]
Mechanical grippers
One of the most common effectors is the gripper. In its simplest manifestation, it consists of just two fingers which can open and close to pick up and let go of a range of small objects. Fingers can for example, be made of a chain with a metal wire run through it.[56] Hands that resemble and work more like a human hand include the Shadow Hand and the Robonaut hand.[57] Hands that are of a mid-level complexity include the Delft hand.[58][59] Mechanical grippers can come in various types, including friction and encompassing jaws. Friction jaws use all the force of the gripper to hold the object in place using friction. Encompassing jaws cradle the object in place, using less friction.
Vacuum grippers
Vacuum grippers are very simple astrictivedevices that can hold very large loads provided the prehension surface is smooth enough to ensure suction.
Pick and place robots for electronic components and for large objects like car windscreens, often use very simple vacuum grippers.
General purpose effectors
Some advanced robots are beginning to use fully humanoid hands, like the Shadow Hand, MANUS,[61] and the Schunk's hand.[62] These are highly dexterous manipulators, with as many as 20 degrees of freedom and hundreds of tactile sensors.[63]
Locomotion
Rolling robot
For simplicity, most mobile robots have four wheels or a number of continuous tracks. Some researchers have tried to create more complex wheeled robots with only one or two wheels. These can have certain advantages such as greater efficiency and reduced parts, as well as allowing a robot to navigate in confined places that a four-wheeled robot would not be able to.
Two-wheeled balancing robots
Balancing robots generally use a gyroscope to detect how much a robot is falling and then drive the wheels proportionally in the same direction, to counterbalance the fall at hundreds of times per second, based on the dynamics of an inverted pendulum.[64] Many different balancing robots have been designed.[65] While the Segway is not commonly thought of like a robot, it can be thought of as a component of a robot, when used as such Segway refer to them as RMP (Robotic Mobility Platform). An example of this use has been as NASA's Robonaut that has been mounted on a Segway.
One-wheeled balancing robots
A one-wheeled balancing robot is an extension of a two-wheeled balancing robot so that it can move in any 2D direction using a round ball as its only wheel. Several one-wheeled balancing robots have been designed recently, such as Carnegie Mellon University's "Ballbot" that is the approximate height and width of a person, and Tohoku Gakuin University's "BallIP".[67] Because of the long, thin shape and ability to maneuver in tight spaces, they have the potential to function better than other robots in environments with people.[68]
Spherical orb robots
Several attempts have been made in robots that are completely inside a spherical ball, either by spinning a weight inside the ball,[69][70] or by rotating the outer shells of the sphere. These have also been referred to as an orb bot[73] or a ball bot.
Six-wheeled robots
Using six wheels instead of four wheels can give better traction or grip in outdoor terrains such as on rocky dirt or grass.
Tracked robots
Tracked wheels behave as if they were made of hundreds of wheels, therefore are very common for outdoor and military robots, where the robot must drive on very rough terrain. However, they are difficult to use indoors such as on carpets and smooth floors. Examples include NASA's Urban Robot "Urbie".
Walking applied to robots
Walking is a difficult and dynamic problem to solve. Several robots have been made which can walk reliably on two legs, however, none have yet been made which are as robust as a human. There has been much study on human inspired walking,
ZMP technique
The zero moment point (ZMP) is the algorithm used by robots such as Honda's ASIMO. The robot's onboard computer tries to keep the total inertial forces (the combination of Earth's gravity and the acceleration and deceleration of walking), exactly opposed by the floor reaction force (the force of the floor pushing back on the robot's foot). In this way, the two forces cancel out, leaving no moment (force causing the robot to rotate and fall over).[80] However, this is not exactly how a human walks, and the difference is obvious to human observers, some of whom have pointed out that ASIMO walks as if it needs the lavatory.ASIMO's walking algorithm is not static, and some dynamic balancing is used (see below). However, it still requires a smooth surface to walk on.
Hopping
Several robots, built in the 1980s by Marc Raibert at the MIT Leg Laboratory, successfully demonstrated very dynamic walking. Initially, a robot with only one leg and a very small foot could stay upright simply by hopping. The movement is the same as that of a person on a pogo stick. As the robot falls to one side, it would jump slightly in that direction, in order to catch itself.[84] Soon, the algorithm was generalized to two and four legs. A bipedal robot was demonstrated running and even performing somersaults.A quadruped was also demonstrated which could trot, run, pace, and bound.[86] For a full list of these robots, see the MIT Leg Lab Robots page.
Dynamic balancing (controlled falling)
A more advanced way for a robot to walk is by using a dynamic balancing algorithm, which is potentially more robust than the Zero Moment Point technique, as it constantly monitors the robot's motion, and places the feet in order to maintain stability.[88] This technique was recently demonstrated by Anybots' Dexter Robot,[89] which is so stable, it can even jump.[90] Another example is the TU Delft Flame.
Passive dynamics
Perhaps the most promising approach utilizes passive dynamics where the momentum of swinging limbs is used for greater efficiency. It has been shown that totally unpowered humanoid mechanisms can walk down a gentle slope, using only gravity to propel themselves. Using this technique, a robot need only supply a small amount of motor power to walk along a flat surface or a little more to walk up a hill. This technique promises to make walking robots at least ten times more efficient than ZMP walkers, like ASIMO.
Other methods of locomotion
The autopilot can control the plane for each stage of the journey, including takeoff, normal flight, and even landing. Other flying robots are uninhabited and are known as unmanned aerial vehicles (UAVs). They can be smaller and lighter without a human pilot on board, and fly into dangerous territory for military surveillance missions. Some can even fire on targets under command. UAVs are also being developed which can fire on targets automatically, without the need for a command from a human. Other flying robots include cruise missiles, the Entomopter, and the Epson micro helicopter robot. Robots such as the Air Penguin, Air Ray, and Air Jelly have lighter-than-air bodies, propelled by paddles, and guided by sonar.
Snaking
Several snake robots have been successfully developed. Mimicking the way real snakes move, these robots can navigate very confined spaces, meaning they may one day be used to search for people trapped in collapsed buildings. The Japanese ACM-R5 snake robot can even navigate both on land and in water.
Skating
A small number of skating robots have been developed, one of which is a multi-mode walking and skating device. It has four legs, with unpowered wheels, which can either step or roll. Another robot, Plen, can use a miniature skateboard or roller-skates and skate across a desktop.
