Industrial robots were initially kept in cages to protect human workers from any unpredictable behavior that the robots may exhibit. The development of collaborative robots has eliminated the need for cages as they are allowed to interact directly with the workers as they collaborate to execute a task. This article will try and try and unfold the mystery behind the working of these cobots.
Common attributes of collaborative robots
1. Light weight
Collaborative robots mainly feature a robotic arm made of light-weight materials. This makes it easy to carry it from one work station to another to execute different tasks.
Collaborative robots were designed to improve safety at the workplace. They are equipped with sensors which enables them to determine if there is any barrier in their work envelope. The sensors give the robot the knowledge that a person is on their way and the exact location of the worker on the work envelope. It gives a command to the robot to stop and avoid any collision. Once the worker moves out of the way of the robot, it resumes its work immediately. This serves to keep the distraction time to a minimum and reduce the wear and tear caused on the robot.
3. Cost effective
Unlike the traditional robots which required huge amounts of initial capital, this new generation of industrial robots for sale is cheaper. This was meant to facilitate their adoption by small and medium companies who can’t afford the expensive robots. Collaborative robots also tend to be easier to maintain as well as operate.
Once you buy a collaborative robot you don’t need to outsource the services of a programmer to get started. They are easy to program as they are equipped with an user interface that anyone can operate.
What are the different ways of collaborating?
As collaborative robots are fast growing in the market, it is important to understand how they are able to collaborate with human workers. Some of the ways to collaboration approved by ISO include;
· Hand Guiding
A human worker makes illustrations with his hand and an external device feeds the direction, the pressure applied and speeds of the hand to the robot. This is very effective way of teaching the robot how it is expected to carry out its tasks. The operator can also use of a visual system linked to robot to guide it in handling of very heavy objects.
· Force and Power Limited
This type of collaboration involves the use of robots specifically in areas within their force and power limitations. This helps to avoid instances of injury caused to human incase a robot takes up objects that it can’t handle the workload.
· Speed monitoring
This involves the use of a technology that measures safety rates to analyze any risks that may involve the use of robots at certain speed levels. This enables the determination of what speed and reach into the work envelope will be programmed on the robot so as to create a safe working environment.
Growth factor in collaborative robots market
There has been an increase in the use of collaborative robots in different industries around the world. This can be attributed to the fact that industries around the world. This can be attributed to the fact that the robots retail of low prices. This increases the return on investment of the companies making them preferred over the robots.
Another growth factor is the advancement of technology which has led to the development of a simple to use consumer interface. This makes collaborative robots more user-friendly as one doesn’t require any programming knowledge to operate it. They are also flexibly programmed enabling them to be used for a variety of activities. The fact that they can be easily moved from one to place implies that they can be leased out to another company for use for a while which in turn generates higher returns for the company.
