UR20 vs DOBOT CR20A: 20 kg Cobot Comparison of Price, Speed and Palletizing
Updated: 9 hours ago
IN A NUTSHELL
🔎 THE KEY DIFFERENCE Both are compared at 20 kg. Universal Robots UR20 has the longer stated reach, which may help reach separated fixtures; it does not guarantee access at every tool angle. |
→ CONSIDER Universal Robots UR20 Consider it when extra reach is useful while the compared load capacity is the same. This article compares 20 kg with a published reach of 1750 mm; include the gripper and part in the load. |
→ CONSIDER DOBOT CR20A Consider it when its stated load and reach already cover your task and its controls fit your equipment. This article compares 20 kg with a published reach of 1700 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 UR20 and the DOBOT CR20A are 20 kg cobots with almost the same reach, aimed at palletizing and heavy handling. The CR20A costs well under half as much and publishes slightly higher speed and tighter repeatability. The UR20 is lighter and better protected.
Quick verdict. The DOBOT CR20A is the clear value choice, with a listed price about 57% lower, a 5.5 m/s speed and ±0.05 mm repeatability. The UR20 is the better choice for wet or dusty areas and lighter installations, with IP65, ISO Class 4 and a 64 kg arm.
