FANUC M-20iD/12L vs Yaskawa AR1440: 12 kg Robot Comparison
Updated: 12 hours ago
IN A NUTSHELL
🔎 THE KEY DIFFERENCE Both are compared at 12 kg. FANUC M-20iD/12L has the longer stated reach, which may help reach separated fixtures; it does not guarantee access at every tool angle. |
→ CONSIDER FANUC M-20iD/12L Consider it when extra reach is useful while the compared load capacity is the same. This article compares 12 kg with a published reach of 2272 mm; include the gripper and part in the load. |
→ CONSIDER Yaskawa Motoman AR1440 Consider it when its stated load and reach already cover your task and its controls fit your equipment. This article compares 12 kg with a published reach of 1440 mm; include the gripper and part in the load. |
💡 THE TAKEAWAY Choose the robot that handles your actual tool and part through the required path, with controls and support your team can use. Compare complete installation quotes, rather than arm-only prices. |
The FANUC M-20iD/12L and the Yaskawa Motoman AR1440 both carry 12 kg. The M-20iD/12L reaches 2272 mm for large parts. The AR1440 reaches 1440 mm, repeats to ±0.02 mm, weighs 150 kg and is listed at about a third of the price.
Quick verdict. The Yaskawa AR1440 is the better value for welding within 1.44 m, with ±0.02 mm and a listed price $37,500 lower. The FANUC M-20iD/12L is the better choice for large parts and multi-process cells that need 2.27 m reach.
