Industrial robots come in diverse forms, each tailored to meet specific needs within manufacturing and production. Below are the six primary types of industrial robots and their distinctive roles:

  1. Articulated Robots: Articulated systems, which feature rotary joints, excel in tasks requiring high flexibility, such as welding, assembly, and painting. Their design mimics a human arm, allowing a wide range of motion.
  2. SCARA Robots (Selective Compliance Assembly Robot Arm): SCARA systems, known for their speed and precision, excel in assembly and pick-and-place operations. They primarily handle small-scale applications like electronics and pharmaceuticals. Cartesian systems, operating along three linear axes (X, Y, and Z), deliver high accuracy in CNC machining, 3D printing, and material handling tasks. Their simplicity makes them cost-effective and easy to program.
  3. Delta Robots: Delta systems feature a spider-like design and perform high-speed, lightweight tasks like packaging and sorting in the food and beverage industry.
  4. Cylindrical Robots: These systems feature a rotary base and a prismatic joint for linear motion. They are ideal for applications like material handling and spot welding, offering a balance of simplicity and functionality.
  5. Collaborative Robots (Cobots): Cobots, designed to work alongside humans, prioritize safety while performing tasks such as assembly, inspection, and machine tending. Their adaptability makes them increasingly popular in modern industries.

The food industry has embraced industrial automation systems to meet the growing demand for efficiency, hygiene, and scalability.

  1. Packaging and Sorting: Delta systems handle rapid sorting and packaging of food products, ensuring minimal human contact and maintaining hygiene standards.
  2. Palletizing: Cartesian and articulated systems automate the stacking of packaged goods, enhancing the speed and consistency of supply chain operations.
  3. Food Handling: Collaborative systems manage the delicate handling of baked goods, fruits, and vegetables, ensuring minimal damage.
  4. Quality Control: Vision-integrated systems inspect food products for defects, ensuring consistent quality and safety compliance.

By integrating robotics, the food industry achieves higher efficiency, reduced waste, and compliance with stringent hygiene standards.

Let's Ask the expert Trevor

The six types are articulated robots, Cartesian robots, SCARA robots, cylindrical robots, delta robots, and polar robots.

The five industrial robots include articulated robots, Cartesian robots, SCARA robots, delta robots, and collaborative robots (cobots).

The four types are articulated robots, Cartesian robots, SCARA robots, and delta robots.

The three types are articulated robots, SCARA robots, and Cartesian robots.

The top seven in the field of automation are recognized for their advanced capabilities and widespread applications. These include articulated models, which offer exceptional flexibility; SCARA systems known for speed and precision; and delta models, ideal for lightweight tasks. Cylindrical designs are valued for their balance of functionality and simplicity. Collaborative systems, often called cobots, prioritize safety while working alongside humans. Cartesian systems excel in accuracy and linear tasks, making them reliable in 3D printing and CNC machining. Lastly, autonomous mobile solutions navigate and operate independently, transforming industries like warehousing and logistics with unparalleled efficiency and scalability.

The "big four" refers to companies leading the automation industry with innovation and global impact. ABB is renowned for its advanced systems catering to various industries, including manufacturing and logistics. Fanuc specializes in CNC-controlled systems and is a pioneer in industrial automation. KUKA focuses on solutions for smart production, particularly in automotive and aerospace sectors. Yaskawa stands out with its expertise in motion control and collaborative systems, making it a key player in flexible and efficient automation. These companies drive innovation, set benchmarks, and lead the way in adopting intelligent technologies across diverse sectors worldwide.

The most common industrial machine is the articulated type. Known for its versatility and range of motion, it resembles a human arm with multiple joints. Articulated models are widely used in various industries, including automotive, manufacturing, and assembly lines. They handle tasks like welding, painting, and material handling with precision and efficiency. Their ability to rotate and move in multiple axes makes them suitable for complex operations that require flexibility and accuracy. This design is highly adaptable, which contributes to its popularity across different sectors that demand a balance of speed, precision, and reliability in their automated processes.

The four major configurations include articulated, Cartesian, SCARA, and delta designs. Articulated models feature multiple rotary joints for flexible motion. Cartesian configurations operate along three linear axes (X, Y, Z), providing high precision in straight-line movements. SCARA types are known for their speed and accuracy in horizontal tasks, making them ideal for assembly and pick-and-place operations. Delta models, with a spider-like structure, excel in high-speed tasks such as sorting and packaging. Each design serves specific purposes, ensuring efficiency and productivity in industrial settings where automation and specialized movements are essential for streamlined operations.

The five generations of machines reflect advancements in technology over time. The first generation focused on simple, repetitive tasks with basic programming capabilities. The second introduced more sophisticated control systems, enabling greater precision and functionality. The third generation saw the integration of sensors, allowing adaptive and responsive movements. Fourth-generation machines emphasized connectivity and real-time data sharing, aligning with Industry 4.0 principles. The fifth generation is marked by advancements in artificial intelligence, machine learning, and autonomy, creating smarter, self-optimizing systems. Each generation has built upon the last, evolving to meet the growing demands of modern industries and technological innovation.
