Collaborative robots

Collaborative robots – or cobots for short – are robots that can work directly with humans without traditional safety devices such as fences or cages. They are an exciting topic in automation technology, especially for companies that want to automate flexibly.

Key facts about collaborative robots are listed below.

Cobots can be a good option – but they are not the only one: we analyse, compare and implement the assembly concept that makes the most sense for you, both technically and economically.

The advantages of collaborative robots

  • Automation saves manual labour
    Collaborative robots replace manual intervention – this reduces labour costs and increases reproducibility.
  • Direct physical cooperation with humans
    Cobots can work alongside humans without the need for guards.
  • High flexibility
    Quick changeover and usually easy to attach – ideal for small batch sizes or frequently changing tasks.
  • Simple programming
    Often via intuitive user interfaces or even ‘teach by demonstration’ (demonstration by hand).
  • Cost efficiency
    Sometimes lower investment costs for smaller applications.
  • Space saving
    No safety cage required – ideal in confined production environments.
  • Fast commissioning
    Short installation and integration time.

Possible restrictions on the use of collaborative robots

  • Limited payload and speed
    To remain safe, cobots work more slowly and often only move a few kilograms.
  • Increased safety requirements
    Even without a cage, risk analyses and additional sensors may be necessary.
  • Not suitable for every task
    Cobots are still reaching their limits when it comes to fast, heavy or very precise processes.
  • Economic efficiency questionable for large series
    Solutions with classic industrial robots are often more efficient for large quantities.
  • Higher demands on the workplace
    Humans and robots share the same space – this requires clear processes and clean organisation.

Conclusion

Cobots are great for flexible, smaller production tasks – especially where humans need to remain closely involved. For large, fast and fully automated series production, classic industrial robots are superior in many cases.
