UR5e vs DOBOT CR7A: 5–7 kg Cobot Comparison of Price, Payload and Speed
Updated: 9 hours ago
IN A NUTSHELL
🔎 THE KEY DIFFERENCE This is a load-versus-reach trade-off: DOBOT CR7A 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 CR7A 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 CR7A cover a similar work area. The CR7A, from DOBOT's current CRA series, carries 2 kg more, moves faster and costs about 45% less. The UR5e is lighter and has built-in force sensing.
Quick verdict. The DOBOT CR7A is the value choice, with 7 kg payload, a 4 m/s speed and a listed price about 45% lower. The UR5e is the better choice for force-controlled tasks and plants with existing UR cells.
