How have Robots changed Manufacturing Sector?

Robots in the manufacturing industry might be a new concept in some areas. However, this technology has been around for a while. By merging traditional manufacturing methodologies with new technology, manufacturing plants boost their output rate exponentially. By utilizing this trick, many business owners and managers have been able to catapult their companies to success.

Robots have impacted the manufacturing industry positively in several ways. The change brought about by robots in this industry spread wide, boosting productivity and breeding success in many companies. However, unlike what many people assume, robots are not replacing the human workforce. On the contrary, robots are developed to perform tasks that are complex for humans and easy for machines. With these tasks out of the way, humans can focus on developing new ideas and methods to improve their knowledge. When robots are implemented correctly, they catapult an organization to success.

An overview of Manufacturing Robots

The term robot is derived from the word “Robotnik,” a Czech word that means “to slave.” Industries began to utilize robots back in 1960 to tackle mundane or dangerous tasks which humans did not want to undertake. However, these machines did more than fill unwanted factory jobs. When utilized correctly, they tackled these tasks at lightning speed and with great precision.

In the 21st century, robots are utilized to undertake all sorts of tasks which can be categorized using various criteria, for example:

As the cost of labor increases, more manufacturers are turning to robot technologies. Actually, ninety percent of modern robots are found in industries that utilize them to optimize production.

The Main Components of Industrial Robots


Industrial robots feature four main components:

  • The manipulator
  • A controller
  • A Human interface device
  • A Power supply unit

The robot’s manipulator is simply the arm of the machine. It is called so because it can move in various directions. On a V5 work cell, the manipulator moves from an intelligent motor that acts as an actuator. The actuator provides the arm with the force it requires to move around. However, on a manufacturing bot, the force mostly comes from fluid pressure, air pressure, and electric motors.

The controller acts like the system’s brain. It holds the system’s program and receives input signals from the system. After receiving input signals, the controller process the signal and then transmits an output signal to the bot. That is how the system efficiently communicates with various components and with the surgeons.

The power supply provides energy to the robot’s actuators and controller. The energy is usually electrical energy. The industrial bot then takes this energy and utilizes it to make various movements.

The Evolution of Robots

Over the last couple of decades, robots have rapidly evolved. Their evolution has seen them gain application in many different sectors. What’s more, with time, the efficiency and precision of machines have gone up immensely.

Even though most people view robots as a science fiction, they have been around for some time. The first person to file a patent to develop an industrial robot was George Devol back in 1954. Devol then released a working prototype back in 1961. The bot functioned and even looked like a modern robotic arm. The bot could easily carry up to five hundred pounds and could also undertake tasks that most people thought only humans could handle.

Since the invention of this robot, machines have become pretty popular in various industries, for example, automotive industries and agricultural industries.

As per the 21st century, robots now have multiple capabilities and features that automatically make them more productive, flexible, and unique. For example, Cobots (collaborative robots) can work alongside humans on factory floors for improved productivity. Moreover, most cobots can even handle physical interaction. For example, when a worker adjusts the robot’s movement, the machine can quickly memorize and then repeat the adjustment steps automatically.

Robots outside and within the manufacturing industry are slowly gaining senses, for example, vision and touch. These significant innovations have significantly impacted how robots are utilized in the production industry and have also boosted the robot’s application scope.

How have Robots gaining Senses Impacted the Manufacturing Industry and Human Workers?

The Sense of Touch

Due to robots gaining the sense of touch, now various recycling facilities are utilizing them to identify and then separate trash using texture variations. The robots simply “touch” the trash, and then depending on the trash’s texture, they separate it from the lot. Moreover, by combining touch with vision-based ML (machine learning) and artificial intelligence, robots become more efficient and undertake sorting tasks faster than humans. The best part is that, due to machine learning, their precision and speed, companies can entirely rely on machines to sort garbage relieving humans of these dangerous tasks.

Machine Vision

Some industrial robots have LiDAR (Light Detection and Ranging) sensors that help them judge various distances using laser reflections. LiDAR sensor functionality can be compared to how animals, animal-like dolphins, and bats “see” using echolocation. These animals utilize sound waves to pinpoint objects in varying locations. They simply send out sound waves and then estimate the location of an object according to how long it take for the waves to bounce back. Using laser reflections, advanced robotics can imitate this behavior and utilize it to “see” objects.

The Sense of Hearing

Much like echolocation and LiDAR, some machines utilize vibrometry to efficiently detect vibrations. By utilizing this technology, these robots can “hear” conversations and basic sounds with ease. However, this technology is, for now, primarily found in various consumer electronics, for example, smart gadgets. But with more innovations coming in, it will not be long before you find “hearing” robots in the production industry.

Robot Variations

There exist six significant variations of robots that are utilized to undertake various tasks. They include:


These robots bear rotary joints, which help them move in a full range of motion. Due to this full range of motion property, these robots can achieve controlled and precise movements of advanced dexterity and flexibility.


Cartesian robots or gantry/rectilinear robots bear three linear joints. These joints move in three different axes, the x-axis, y-axis, and z-axis. Due to their rigid and unique structure, these robots can make simple movements with enhanced repeatability and precision. Moreover, these robots are cheap because they don’t require extensive movement. Plus maintaining this robots comes at a cheap cost due to the same feature.

Cartesian robots are primarily utilized to carry out assembly tasks, for example, picking and moving bottles from one location to another.


As the robot’s name suggests, the cylindrical robots bear a working area that is cylindrical. In addition, these robots have a robotic arm attached to the bot via one joint. The arm’s links are then connected using another linear joint to ensure perfect functionality.

The robotic arm connected to the bot can move up and down, and it can also move around a cylindrical pole. Just like gantry robots, manufacturers mainly utilize cylindrical robots to handle assembly operations. Manufacturers prefer cylindrical robots over gantry robots since they can move in between various points faster.


These robots are like a complex variation of cylindrical and Cartesian robots. Spherical robots can tackle operations that require 3-dimensional space movement.

These robots have a complex robotic arm attached to their base using a twistable joint. Due to the placement of the robot arm and its movement, the robot has a work area that is spherically shaped.

SCARA (Selective Compliance Assembly Arm)

SCARA robots bear a robot arm that imitate the human wrist movement. These arms have joints that help them make both horizontal and vertical movements. Due to the “Wrist” like movement, these robots are significant in terms of handling assembly operations, for example, packaging, kitting, et cetera.

Delta Manufacturing Robotics

The Delta bots are built using multiple jointed parallelograms, all attached to one base. Delta industrial robots have a spider-like structure which helps them make precise and delicate movements which are crucial in:

–          The food industry

–          The pharmaceutical industry

–          The electronic industry

Delta robots can efficiently complete highly repetitive operations, for example, parts assembly very fast and with high precision every time. What’s more, manufacturing jobs that are highly repetitive tend to bring about a disorder known as musculoskeletal to human employees when done for an extended period. Therefore delta bots do not just increase productivity of a company. They also help in terms of keeping human employees healthy.

Tasks undertaken By Industrial Robots

Since multiple industrial bot variations exist, their application areas in the manufacturing industry are also vast. Typically most robots in this sector are required for:

–          Buffing

–          Grinding

–          Polishing

–          Painting

–          Packaging and labeling

–          Pick and place

–          Assembly and disassembly

–          Product testing

–          Product inspection

What’s more, robots undertake all these tasks with incredible precision and speed that can’t be matched by human workers.
