For many years, the idea of autonomous robots taking over all work in a factory or assembly line was seen as progress – replacing workers to perform tasks on assembly lines to improve overall efficiency with a high price tag. It is also seen as a threat to the job security of factory workers. Much has been debated over the years about this topic and the current trend of collaborative robots has emerged as an alternative. Instead of completely replacing factory workers with robots, some companies are looking into the integration of collaborative robots arms, cobots for short, which can work alongside with human workers. They can be programmed to autonomously operate within a limited list of tasks or need human assistance to complete specific applications. The cobots are less expensive than fully functional robots, yet they can operate with much higher precision, perform heavy-duty work in more dangerous conditions, and offer lower error rates than humans. These cobots are usually compact in size, versatile in its use, affordable, efficient and easy to configure, setup and maintain. Human workers are free to perform responsibilities that require manual dexterity, ingenuity and complex problem solving – something that even advanced robots cannot perform just yet.
Collaborative Robot Quickly Gains Popularity
The collaborative robot concept has gained popularity in recent years. Some say these cobots will revolutionize production. It can help smaller operations offer better competition and gain ground in their markets as well as enhance productivity and efficiency in large factories. Experts are seeing a strong growth potential for cobots in the near future. Some said they expect to see the growth level increase tenfold between now and 2020. The price of these cobots is expected to continue to fall, hence, increased adoption rate for use in automation. Mid- to small-size companies soon are expected to be able to enjoy its use and expanded applications. Newer available technologies, i.e., vision sensors and 3D sensors have come into play and help widen the use of cobots. It is certain that cobots will be used in many more new applications as technology progresses and associated costs drop.
How Cobots Work?
The majority of recent cobots are simple robotic arms that consist of computer/embedded boards/systems, sensors, vision systems, human interface units, power supplies, etc. They are programmed to perform specific tasks that may include, inspection for outliers, lifting heavy items, assembling parts, monitoring specific functions of other machines or tasks, moving items and more. These robots can stop themselves on impact with sensors and handle heavy loads beyond human capabilities. It can be programmed for specific movements that human's anatomy is incapable of performing. Most cobots are safe to work alongside humans and can navigate around them to avoid potential injuries.
