UR15 vs Doosan M1509: 15 kg Cobot Comparison of Price, Reach and Precision
Updated: 10 hours ago
IN A NUTSHELL
🔎 THE KEY DIFFERENCE Both are compared at 15 kg. Universal Robots UR15 has the longer stated reach, which may help reach separated fixtures; it does not guarantee access at every tool angle. |
→ CONSIDER Universal Robots UR15 Consider it when extra reach is useful while the compared load capacity is the same. This article compares 15 kg with a published reach of 1300 mm; include the gripper and part in the load. |
→ CONSIDER Doosan M1509 Consider it when its stated load and reach already cover your task and its controls fit your equipment. This article compares 15 kg with a published reach of 900 mm; include the gripper and part in the load. |
💡 THE TAKEAWAY Check the real tool, movement path and safety assessment before choosing. A collaborative label does not make every task safe without guarding; compare complete installation quotes. |
The Universal Robots UR15 and the Doosan M1509 both carry 15 kg. The UR15 adds reach, speed and IP65 protection. The M1509 is more compact, more precise and much less expensive.
Quick verdict. The Doosan M1509 is the better value for compact heavy-part handling, with a listed price about 27% lower, ±0.03 mm repeatability and a 32 kg arm. The UR15 is the better choice for reach, speed and harsh environments, with 400 mm more reach, a 5 m/s tool speed and IP65.
