UR5e vs DENSO COBOTTA PRO 900: 5–6 kg Cobot Comparison at the Same Price
Updated: 10 hours ago
IN A NUTSHELL
🔎 THE KEY DIFFERENCE DENSO COBOTTA PRO 900 has the higher stated load capacity and longer stated reach. Those figures help shortlist it for heavier loads or wider layouts, but do not prove a faster production cycle. |
→ CONSIDER Universal Robots UR5e Consider it when its stated load and reach already cover your task and its controls fit your equipment. This article compares 5 kg with a published reach of 850 mm; include the gripper and part in the load. |
→ CONSIDER DENSO COBOTTA PRO 900 Consider it when additional load capacity and reach matter. This article compares 6 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 UR5e and the DENSO COBOTTA PRO 900 are listed at exactly the same price and repeat to the same ±0.03 mm. The COBOTTA PRO 900 carries a little more and reaches a little further. The UR5e is considerably lighter and comes with built-in force sensing.
Quick verdict. The DENSO COBOTTA PRO 900 offers 1 kg more payload, 50 mm more reach and a 2,100 mm/s TCP speed at the same price. The UR5e is the better choice for lighter installations and force-controlled tasks, with a 20.6 kg arm and a built-in force/torque sensor.
UR5e and DENSO COBOTTA PRO 900 at a glance
The UR5e carries 5 kg over 850 mm, repeats to ±0.03 mm and weighs 20.6 kg. The UR7e takes its place in the current Universal Robots range.
The COBOTTA PRO 900 carries 6 kg over 900 mm, repeats to ±0.03 mm, weighs 29 kg and runs on the DENSO RC9 controller.

Price comparison
UR5e: listed from $35,000
DENSO COBOTTA PRO 900: listed from $35,000
Difference: none at list price
With identical list prices, the decision rests on payload, weight, sensing and the controller platform already used in the plant.
Payload, reach and precision
The COBOTTA PRO 900 carries 6 kg, 1 kg more than the UR5e, and reaches 900 mm, 50 mm more. Both publish ±0.03 mm repeatability, so precision is not a deciding factor.
Weight and mounting
The UR5e weighs 20.6 kg, about 8 kg less than the COBOTTA PRO 900. That difference matters on carts, light pedestals and mobile bases, and when the robot needs to be moved between machines.
Speed
DENSO publishes a 2,100 mm/s maximum TCP speed for the COBOTTA PRO 900. Universal Robots publishes 180°/s maximum joint speed on all six joints for the UR5e.
Sensing and safety
The UR5e has a built-in 50 N / 10 Nm force/torque sensor and 17 configurable safety functions certified to EN ISO 13849-1 (PLd, Category 3). For either robot, collaborative operation should be confirmed by a risk assessment of the final cell.
Programming and software
The UR5e runs PolyScope with hand-guided teaching and supports Modbus TCP, PROFINET and EtherNet/IP, with UR+ accessories. The COBOTTA PRO 900 runs on DENSO's RC9 controller, and DENSO notes that programming interfaces, licences and simulation tools vary by package.
