Conclusion  
HRC systems have evolved rapidly in recent years while the various standards governing industrial robots are currently lagging behind the technology. EN ISO/TS 15066 has been released to provide more detailed information and guidance to support manufacturers seeking to achieve conformance with the EU Machinery directive.
 
Control systems play a key role in the implementation of HRC safety systems, such as safety-rated monitored stop and performance levels, and must be met to ensure conformance. However, many of the solutions necessary to comply with these standards, such as sensors, controllers and output devices, already exist. By selecting SRP/CSs with appropriate Performance Levels designers can simplify the development process while easing the certification of their products.
