Trying to design a robotic application where the operator and robot need to work in the same space? The top 2 decisions when selecting the best collaborative robot are:
- How closely do the operator and robot need to work together?
- What brand of collaborative robot should we select?
How closely do the operator and robot need to work together?
Collaborative operations are defined in ISO 10218, ISO/TS 15066 based on 4 levels of safety. FANUC has developed hardware and software solutions for each type of operation.
- Safety-rated monitored stop – the robot is stopped when operator is in the robot zone.
- Hand guiding – read more
- Speed and separation monitoring – robot and operator can work in the same area, but speed of the robot is controlled by zones. This means as the operator approaches, the robot slows, and as the operator enters the robot space, the robot stops. Read more
- Power and force limiting – The robot and operator work and interact in the same space. The robot is specially designated to work collaboratively and the robot speed is adjusted and force is limited to the ISO standards for under 210N.
From the four collaborative descriptions above, only one actually requires a collaborative robot. So, it is important when looking at your application you only select a collaborative robot when the operator must actually interact with the robot. Otherwise, there are safety solutions that can be put in place allowing different levels of collaboration.
What brand of collaborative robot should we select?
There are a variety of collaborative robot companies and robot options. FANUC robotics is the leading supplier of industrial robots with almost 60 years’ experience. Based on this resume, taking a look at FANUC’s collaborative options, to see if they have the best collaborative robot, is a must.
While FANUC has a full line of industrial robots (payloads range from .5kg to 2300kg), below are the collaborative models that have been developed for applications required by robotic customers.

The Main Benefits of Selecting a FANUC Collaborative Robot Model
- FANUC’s collaborative options offer a high degree of functionality and durability at a small cost difference over other available brands.
- FANUC offers a full line of robots for your industry – meaning you can have one robot platform for your entire facility, handling everything from smallest to largest load and easiest to most challenging cycle time/duty cycle.
- FANUC’s collaborative robots are under the Service First guarantee from not only FANUC, but FANUC authorized integrators. FANUC also supports all robots for the life of production.
- All FANUC robots come hardware ready for integrated iRVision and force sensing capabilities.
- FANUC’s Dual Check Safety software provides very high granularity and the ability to create complex shapes for safe zones around the robot arm and in the robot work-space, not just simple Cartesian planes and block zones.
- I/O signals, integrated valves, and air can be run inside the FANUC CR35 and LR Mate collaborative robot arms for simpler, cleaner end of arm tool dressout.
- FANUC’s collaborative robots offer better, more complete connectivity to external safety devices such as Devicenet, Ethernet/IP Safe, etc.
- FANUC collaborative options are very accurate and repeatable within the full operating range and capacity of each robot ( .02mm repeatability on LR Mate CR-4iA, .03mm on CR-7iA).
