Every day, countless industries utilize robotics to improve their production processes and maximize efficiency. But have you ever wondered what types of robots exist? From robotic arms to autonomous vehicles, there’s a wide variety of robot models developed for various applications. As we discover more about industrial automation technology, it’s key to understand the different kinds of robots on the market today and how they’re used in industry. In this blog post, we will explore the different types of industrial robots available and discuss their advantages and disadvantages.
What Is an Industrial Robot?
Industrial robots can also help reduce the number of employees needed for certain operations while still producing higher quality results than manual labor could provide. Industrial robots come in a wide variety of shapes and sizes, with some even having the ability to move around freely on their own. These advanced robotic systems are commonly found in factories, warehouses, distribution centers, and other industrial settings where they assist with repetitive or dangerous tasks that would otherwise require human labor.
Industrial robots can be controlled by a variety of methods including manually, through software programming, or with a combination of both. They can be programmed to perform specific tasks or operate autonomously depending on the project requirements. With advances in artificial intelligence (AI) and machine learning, more intelligent and complex robotic systems are being developed that have the capacity to learn from their environment, problem solve, and make decisions based on data input. These cutting-edge industrial robots will continue to revolutionize manufacturing processes around the world for years to come. 
Types of Industrial Robots
Cartesian Robots: Pros and Cons
Cartesian robots, also known as linear robots, are the simplest and most affordable industrial robot type. They use a series of linear movements to perform tasks such as welding, assembly and cutting. These types of robots are typically used for small-scale operations in industries such as automotive or electronics manufacturing.
- Easy to program – Cartesian robots are relatively easy to program due to their simple design and motion paths. This makes them an ideal choice for smaller businesses who cannot afford more complex robotic systems.
- Low cost – Cartesian Robots are generally cheaper than other types of industrial robots, making them attractive to businesses with limited budgets.
- Safe – Cartesian Robots have fewer moving parts than other types of industrial robots, making them safer to operate. They also have the ability to stop immediately if something unexpected occurs.
- Limited range of motion – Cartesian Robots have limited ranges of motion due to their linear design. This limits their application to simple tasks such as assembly and welding.
- Low accuracy – Cartesian Robots tend to have lower accuracy than more complex robot types due to their linear paths of motion. This means they are not suitable for tight tolerance applications or delicate operations.
- High maintenance costs – Cartesian Robots require frequent maintenance due to their simple design and lack of sophisticated features. This can increase operational costs over time. 
Articulated Robots: Pros and Cons
Articulated robots are known for their flexibility and versatility. They can execute complex tasks, such as welding, painting, and manipulating objects in three-dimensional space. This makes them useful in many industries such as automotive manufacturing and medical research.

- They offer a high degree of flexibility and can perform multiple tasks without requiring major modifications.
- These robots typically have a long lifespan, making them ideal for applications that require consistent performance over many years.
- Their relatively low cost makes them an attractive option for businesses on a tight budget.
- Cylindrical robots may be limited in terms of their reach and the range of motion they can achieve. This could make them unsuitable for certain jobs that require precise movements or lengthy reach distances.
- The accuracy and repeatability of these robots may also be lower than other types of robot arms, making them less suitable for applications that require precise movements.
- They can only handle lighter objects and are not designed to carry heavy payloads, so they may not be suitable for certain tasks or materials.
- Finally, these robots require frequent maintenance because of their complex mechanical components. This can add to the overall cost of ownership over time. 
Delta Robots: Pros and Cons
Delta robots are becoming increasingly popular in industrial automation due to their high efficiency and precision. These robots feature three arms connected to motors at the base, allowing them to move quickly and accurately in three axes with large payloads.

- Expensive upfront cost – The initial cost to purchase or rent a delta robot is higher than other types of industrial automation solutions, such as SCARA or Cartesian robots.
- Complex programming – Due to their complex structure, delta robots may require more advanced programming skills than some other automation options.
- Limited reach – Since delta robots are confined by the size and shape of their base, they usually have a relatively small reach which can limit the number of tasks they can perform.
- Reliability – Although delta robots are generally reliable, their complex structure can be prone to breakdowns which may result in longer downtimes. 
Polar Robots: Pros and Cons
Polar robots are increasingly popular in modern robotics. They come with a variety of features and advantages, but they also have some drawbacks that should be considered before making the decision to purchase one.
- Polar robots can move quickly in any direction without having to change their orientation or turn around. This makes them particularly useful for navigating tight spaces and completing complex tasks.
- Polar robots can operate on their own power source, which eliminates the need for external energy sources like electricity or batteries. This makes them ideal for indoor environments where traditional power sources may not be available.

What type of robot is an industrial robot?
Industrial robots are automated, programmable and capable of movement on three or more axes. They are typically used in industrial manufacturing applications to perform tasks such as welding, assembly, painting and material handling. Industrial robots may be stationary or mobile and can range from simple picking devices to complex multi-jointed robotic arms with grippers, vision systems and other sensing instruments.
What is the role of a robot programmer?
A robot programmer is responsible for developing software that enables robots to carry out tasks autonomously. This involves writing programs that define how the robot moves, what sensors it uses to detect its environment, and how it should respond to different stimuli. The programming language used depends on the type of robot being programmed; common languages include C, C++, Java, Python and MATLAB. The programmer must also be familiar with the hardware components of the robot in order to develop an efficient program that meets the specifications of a given project. In addition, they may be required to debug existing software or troubleshoot issues encountered by users. Finally, a robot programmer is responsible for maintaining and updating their programs as needed.
What are the 3 main parts of an industrial robot?
The actuator provides the robot with motor power and motion control. It is typically composed of servo motors, gearboxes and other mechanical parts. The controller acts as a central processing unit that stores instructions for the robotic system, including how it should move and respond to different stimuli. Finally, the end effector is the tool used by the robot to complete tasks; this can be anything from a welding tool to a gripper or vacuum cleaner nozzle.
What is the most common type of industrial robot?
The most common type of industrial robot is the articulated robotic arm. This consists of several joints connected by links that can be controlled to move in different directions and at different speeds. The arm can also be fitted with sensors such as vision systems or tactile feedback devices, which enable it to interact with its environment and complete tasks autonomously. Articulated robots are commonly used for welding, painting and assembly applications.
