How Collaborative Robots Can Power Sustainable Manufacturing Practices

Robotics

Sustainability ranks high on both the global and political agenda as many countries continue to set bold energy and emission targets. These commitments have companies around the world prioritising their sustainability efforts to help fight climate change, and this movement is set to soar in 2022.

Like many others, Universal Robots (UR) works tirelessly to make its own working practices and production more sustainable. With this in mind, James McKew Regional President for Universal Robots Asia Pacific answers the pressing question of: “What makes a manufacturing process more environmentally ‘sustainable’?”

“Well, if you ask 10 different manufacturers around the globe, you are likely to get 10 different answers.  However, when it comes to the use of robots that can work safely alongside humans, fondly dubbed as cobots (collaborative robots), some common themes unite the ever-growing list of sustainable manufacturing initiatives.”

Amongst these, the following initiatives are most tangible and are ranked as follows:

  1. Waste reduction
  2.  Energy consumption
  3. Space saving production processes
  4. Reshoring initiatives.

McKew believes that cobots have proven to be an effective tool in helping manufacturers improve their bottom line whilst fostering sustainable practices. He highlights five ways that cobots help to improve customers’ footprints as follows:  

  1. Reducing waste

“As part of our commitment to eliminating defects and waste during the manufacturing process, we recently deployed a UR3 cobot at Italian power tool maker RUPES to help achieve its ‘zero defects’ production target,” explains McKew.

This deployment resulted in reduced waste, lowered operating costs, enhanced productivity, improved working conditions as well as the allocation of workers to higher value tasks.

As the RUPES example shows, one of the most effective ways to reduce waste is to improve the quality of your manufacturing procedures.  

 

“Universal Robots’ commitment to the fact that Quality Matters provides significant reassurance for manufacturers concerned about the sustainability of their operations. In fact, not only are UR cobots manufactured according to high quality standards, but they are proven tools for reducing waste and increasing efficiency across a wide range of manufacturing businesses and processes, from thermoplastics and precision optics manufacturing to welding and automotive production.”

 

  1. Reduced energy consumption

 

By means of remote monitoring and access, companies can now reduce their energy consumption.

Explains McKew: “Reduced travel costs, optimized energy consumption and the streamlining of automation processes through digitlisation all play a key role in driving sustainability.”

 

The UR+ ecosystem supports digitalisation with a wide range of remote monitoring and access solutions. “Remote monitoring tools allow users to track and monitor cobot performance without having to go on-site.”

 

Typically accessible via tablet, PC and smartphone, these tools provide a wealth of information on KPIs that can then be used to tweak the cobots’ performance, resulting in improved production efficiency and reduced electricity consumption.

 

3.     Environmentally friendly footprints

Traditional automation typically boasts a large footprint and requires that numerous changes be made to the layout of a production facility. “In some cases, new construction is required to accommodate the robot,” adds McKew. “In contrast, UR’s lightweight cobots offer a small footprint and based on the risk assessment, most cobots require no safety guarding, making them easy to move between applications whilst eliminating costly facility redesigns.”

 

In a recent success story, Thailand-based company, Benchmark Electronics deployed four UR5 and two UR10e cobots to help improve their operational efficiencies by 25%. This also saved them 10% manufacturing floorspace.

 

4.     Bringing production home

Minimising the distance involved in supply chains reduces transportation costs and is better for the environment. Coupled with uncertainty about the resilience of global supply chains, these environmental concerns have spurred reshoring efforts. “UR cobots empower these efforts by allowing manufacturers to compete with lower-wage countries whilst keeping production close to home.”

 

  1. Maximising energy efficiency in cobot deployments

 

Generally speaking, cobots are more affordable and consume less energy than their traditional robot counterparts. There are very simple steps manufacturers can take to minimise energy consumption in their cobot-powered applications; running your cobot at 70-80% of its maximum speed and payload, where possible, will reduce energy usage and extend the lifespan of the cobot. And when it comes to application design, make sure to consider path optimisation strategies as this will also reduce electricity consumption when the cobot is up and running.
