Collaborative Robots

In the past, robots were huge and robust gadgets which executed duties outlined for them. They came with bright colors to caution workers of their imminent danger. They were encircled with protectors and a fence for security reasons. Setting them up was an arduous task and one needed to have excellent programming skills to set them up.

Today, technology has evolved and this has seen the emergence of collaborative robots which are light, compact, and adept.

 What Are Collaborative Robots

A collaborative robot is a machine that is specially designed to interact directly with humans in a collaborative environment. There are various terms individuals need to understand when it comes to these gadgets as illustrated below.

Cobot. This is the short form of collaborative robot

Collaborative operation/Human Robot Interaction. This is the condition by which humans and a function designed robot works directly within a designated environment

Collaborative environment/workspace. This is a protected area where humans and the robot execute duties together amid an automatic operation.

IAD (Intelligent Assist Device). This is a non independent smart lift assist gadget

What Are the Collaborative Features For Robots?

Modern day robots come with four collaborative features which are;

Hand Guiding

This collaborative operation involves teaching through demonstration. For example, it comes in handy when one needs to teach trails for pick and place operations instantly. While hand guiding relies largely on industrial robots, it comes with an extra gadget that senses the worker’s effort as applied on the robot. More characteristics of hand guiding robots are;

  • Uses path teaching and demonstration
  • Requires an end of arm gadget in order to sense applied forces
  • Uses normal industrial robots
  • Makes specific robot collaborative modes

Safety rated monitored stop

This collaborative characteristic is executed when the robot is working independently. However, a human may need to penetrate its work environment occasionally. For instance, if a particular operation must be executed on a part while it is within the robot’s space. In this case, the robot does most of the work while the worker carries out subordinate operations on the part.

This means that the worker is able to execute his task on the part within the robot’s space. When a person enters a proposed safety area, the robot seizes operations altogether despite the fact that it is still on. These robots work efficiently when humans work away from them with limited close interactions. This reduces the amount of time it stops due to human interruption. More characteristics are;

  • Requires safety gadgets that sense human closeness
  • Utilizes common industrial robots
  • Stops when the safety area is invaded
  • Utilized for inadequate cooperative procedures

Speed And Separation Monitoring

Here, the robot’s workspace is controlled by a vision or laser system that trails the worker’s position. The robot then operates within the functions of the predetermined safety area. For instance, if the worker is within a specific safety zone, the robot works slowly and continues to slow down further as he approaches. It eventually stops when they get too close. More features are;

  • It requires a vision system in order to sense the nearness of the human
  • It uses common industrial robots
  • It is utilized for operations that need frequent human presence

Power and Force Limiting

This is one of the most human friendly robots because it allows human robot interaction in the absence of extra safety gadgets. It is capable of sensing unusual forces along its path. It is specially programmed to stop every time it reads a force overload. Additionally, it is designed to use up forces in the event of impact within a wider surface. This explains why robots are rounded and have no defined motors. Third parties for human robot collaboration industrial safety accredit many of these robots. Its features are;

  • It is not a common industrial robot
  • It does not need extra safety gadgets. However, it will need to undergo a risk assessment
  • It comes with force limited characteristics
  • It is designed to collaborate with the worker directly

Finally

Force limited robots are easy to integrate with and program. They do not need to be fenced and one does not have to change their production line. This is because they are specially designed to collaborate with humans. They come with the hand guiding feature which cuts down the programming time.
