Fanuc Similarities – the M-16iB/20, ArcMate 120iBe, and M-20iA

Jul 6, 2023

Fanuc robots makes a wide range of systems available to help solve your production needs. Three ARC Mate robots that are versatile and can perform a multitude of processes include the 120iBE, the M-16iB/20, and the M-20iA robot. They have a great repeatability and reach and will improve the overall product quality of your production line.


Fanuc makes a vari­ety of robots that are able to per­form a vast array of tasks – every­thing from arc and spot weld­ing, to mate­r­i­al han­dling, dis­pens­ing, and mate­r­i­al removal func­tions. While not every Fanuc robot can per­form every func­tion on its own, many are ver­sa­tile enough to per­form a mul­ti­tude of process­es, giv­ing them sim­i­lar attrib­ut­es. Three of these robots are the Fanuc ARC Mate 120iBe, the Fanuc M‑16iB/​20, and the Fanuc M‑20iA.

Right off the bat, the eas­i­est sim­i­lar­i­ty between these robots is that they are all six-axis indus­tri­al robots. How­ev­er, that is just the tip of the ice­berg. All of these robots have a 20kg pay­load. The ARC Mate 120iBe, M‑16iB/​20, and M‑20iA all have a 0.08 lev­el of repeata­bil­i­ty. They also have sim­i­lar speeds and motion ranges for their var­i­ous joints. The ARC Mate 120iBe and M16iB/​20 have a reach of 1667mm, while the M20iA has a bit longer reach of 1811mm. They all also have a vari­ety of mount­ing options, includ­ing floor, ceil­ing, angle, and wall mounting.

While the ARC Mate 120iBe shares the abil­i­ty to per­form cut­ting tasks with the M‑16iB/​20 and the M‑20iA, it is pri­mar­i­ly used as a weld­ing robot, while the oth­er two robot mod­els are used for func­tions oth­er than weld­ing. The M‑16iB/​20 and the M‑20iA are both built for many dif­fer­ent appli­ca­tions, includ­ing assem­bly, dis­pens­ing, mate­r­i­al han­dling, machine load­ing and unload­ing, mate­r­i­al removal, water­jet cut­ting, laser cut­ting, and pack­ing. The M‑20iA is also able to per­form pick­ing and machine tend­ing applications.

While the names of their con­trollers may be dif­fer­ent, these three robots are con­trolled in the exact same way. The ARC Mate 120iBe uses a Fanuc RJ3iC con­troller, while the M‑20iA and M‑16iB/​20 use the R‑30iA con­troller. These con­trollers per­form very sim­i­lar func­tions for the robots they con­trol. Both con­trollers are able to con­trol up to 40 axes, and both con­trollers cut down on vibra­tions in the robot­ic sys­tems, allow­ing for reduced accel­er­a­tion and decel­er­a­tion times for the robots it controls.

Over­all, the Fanuc ARC Mate 120iBe and the M‑16iB/​20 share many sim­i­lar attrib­ut­es and capa­bil­i­ties with the M‑20iA. All of these robots also car­ry the long-stand­ing tra­di­tion of qual­i­ty and excel­lence that comes with a Fanuc indus­tri­al robot.
