Types Of Collaborative Robots & What They Are Capable of Doing!

Collaborative Robot

The concept of the collaborative robot model is the result of the growth and complexity of automation technology in almost every field of modern industrialization. The idea that robots are more than just mechanical devices that perform repetitive motion is changing as to that even they can understand, reason, and behave in the same way that people do. Many of these features are possible with the help of cutting-edge technology and breakthroughs in sensor-based learning systems, as well as artificial intelligence that has evolved well beyond what it was just a decade ago. The collaborative robot business is thriving, and analysts predict that it will continue to grow.

In this article, we will discuss in detail the Cobots or the collaborative robots that are changing the concept of industrial advancement as humans can now collaborate better with machines. We will check out the various types of such robots and analyze the collaborative robot market today as well as its future.

What is a Collaborative Robot?

A collaborative robot is one that collaborates with humans in some manner, such as as an assistant in a task or process, or as a guide. In contrast to autonomous robots, which operate mostly on their own and without supervision, collaborative robots have programs that respond to human commands and actions. Although the construction of collaborative robots is in a variety of ways, the tech industry has reached an agreement on the basic engineering concepts and characteristics that are utilized to construct them. There is the safety monitored stop function, which allows the robot to momentarily halt operations based on human proximity, and the hand-guide feature, which allows robots to learn from people physically leading infrastructure for a certain process or activity. Other approaches to ensure uniform standards for robot performance include speed and separation monitoring, as well as power and force restriction.  

Types of Cobots 

The classification of collaborative robots divides them into four types: safety monitored stop, speed and separation, power and force limiting, and hand directing.  

1. Safety monitoring cobots

When most people hear the word collaborative robots, they will likely think of power and force limiting cobots. These robots are especially intended to interact with humans without the use of extra safety barriers, vision systems, or external scanners.  

2. Force and power limiting collaborative robots

Power and force limiting cobots or collaborative robots are such that they have no pointed or any sharp edges, exposed motors, or pressure areas, further boosting human safety. Power and force restricting cobots have sophisticated collision monitors built into function securely alongside human employees hence, preventing any crash of high impact movement. These monitors enable the cobot to identify potential collisions and to stop instantly if it comes into touch with a person. Cobots with low power and force are currently confined to minor applications.  

3. Separation and Pace collaborative robots  

Speed and separation cobots, like safety, monitored halting cobots, are similar to a typical industrial robot, however, speed and separation robots are better designed for applications that will have regular communication with human workers. Hence, usage of the advancements such as vision systems is common in speed and separation of cobots to monitor the cobot's work. The work environment consists of two zones: the warning domain and the stop domain. When a person approaches the warning zone, the cobot slows to a safe speed. If a human operator enters the stop zone, the cObot will instantly come to a halt. The cobot will resume operations as soon as the human worker exits the stop zone. So, the safety of workers is always ensured.

4. Hand Guidance cobots

Hand guidance is a cobot function that allows operators to teach the collaborative robot new pathways and locations by directing it with a hand-held instrument. This functionality enables cobots to be programmed accordingly by the human co-worker, quickly and simply, resulting in little disruption. 

Overview of the Collaborative Robot Market

The worldwide collaborative robot market's worth from 2020 to that after a few years is really high. The pace of its growth at a CAGR of 23.06 percent within the span of five years makes its market really profitable. The robots' low cost and strong return on investment are likely to have a favorable influence on the market. Because collaborative robots employ the latest sensors, plug-and-play technologies, and autonomous robot training using CAD data, they are tools for analyzing the industrial needs of all sizes and sizes to remain competitive.

The collaborative robot market is somewhat competitive, with everyone focusing on what different can be done to stay ahead in the industry. Furthermore, acquisitions and collaborations between major corporations and startups are anticipated.

Applications 

Now that you know about the collaborative robot market scenario, let's dive into the applications of COBOts right now. 

1. Quality and consistency inspection

Collaborative robot arms provide the accuracy and consistency required for your project's success. A robot will follow specific processes and predefined workflows with little variance, giving optimal circumstances for research or analysis. It takes extraordinary talents to perform the very same action with the same accuracy day after day or for several hours continuously. By automating quality inspection, businesses may improve measurement accuracy while maintaining high levels of product quality.

2. Reliability, faster production, and efficiency Improvements

Reduce the risk of injury by relieving machine operators of rigorous physical, repetitious activity. To free up employees for more productive activities, a collaborative robot may be utilized to tend pieces of machinery such as CNC, injection molding, press brakes, stamping presses, and others. Improve process speed and quality while lowering the risk of harm associated with working near the heavy gear.

The collaborative robot arm helps to achieve increased efficiency to compete in a worldwide market, for tasks ranging from assembly to painting, palletizing to screw-driving, packing to polishing, injection molding to welding, or whatever processing operation one can think of. So, in this article, we have discussed the major aspects related to collaborative robots along with their applications which indicate their importance. Hope this was useful in understanding the current trends in automizing a business as well as its benefits.
