UR5e vs DOBOT CR7: 5–7 kg Cobot Comparison of Price, Payload and Precision
Updated: 9 hours ago
IN A NUTSHELL
🔎 THE KEY DIFFERENCE This is a load-versus-reach trade-off: DOBOT CR7 has the higher stated load capacity, while Universal Robots UR5e has the longer stated reach. Start with the constraint your task actually has. |
→ CONSIDER Universal Robots UR5e Consider it when reaching farther matters more than the higher payload of the alternative. This article compares 5 kg with a published reach of 850 mm; include the gripper and part in the load. |
→ CONSIDER DOBOT CR7 Consider it when additional load capacity matters more than extra reach. This article compares 7 kg with a published reach of 800 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 UR5e and the DOBOT CR7 cover similar work areas. The CR7 carries 2 kg more, repeats more tightly and costs about a quarter less. The UR5e reaches a little further, is lighter and has built-in force sensing.
Quick verdict. The DOBOT CR7 is the value choice for heavier tools, with 7 kg payload, ±0.02 mm repeatability and a listed price about 27% lower. The UR5e is the better choice for force-controlled tasks and lighter installations.
UR5e and DOBOT CR7 at a glance
The UR5e carries 5 kg over 850 mm, repeats to ±0.03 mm and weighs 20.6 kg.
The CR7 carries 7 kg over an 800 mm working radius, with a 990 mm maximum reach. It repeats to ±0.02 mm and weighs 24.5 kg. DOBOT has since introduced the CR7A as its successor.
