Collaborative Robots

The main advantage between cobots and other traditional automation or robotics is that the cobot operates alongside the worker in the same space without the need for barriers and exclusion zones.

This does however lead to the main cause of concern; that the interaction between human workers and cobots poses a safety risk. Given the correct risk assessments, and deployed in the right way cobots can actually address safety concerns by providing power assistance or performing dangerous tasks, thus reducing injury and postural risk. There is a trade-off – cobots must operate at much lower speeds and within parameters covering their size and reach. This may reduce their productivity in comparison to enclosed robotic solutions.

Whilst cobots tend to be smaller and slower, with less reach and force, they can operate without barriers or enclosures maximising the available workspace. Advances in sensor technology and data processing enable the safety features that allow collaborative working. So collaborative robots still offer productivity, efficiency and quality improvements but are also more adaptable and can be redeployed relatively easily. Repurposing cobots is a distinct advantage over traditional robot automation. Cobots are relatively easy to teach and can be moved to new locations with minimal adaptation to the environment.
