UR5e vs Flexiv Rizon 4 + F/T Sensor: Cobot Comparison at the Same Price
The Universal Robots UR5e and the Flexiv Rizon 4 + F/T Sensor are both listed from $35,000. The UR5e carries more, repeats more tightly and is faster. The Rizon 4 + F/T Sensor adds a seventh axis, slightly more reach, IP65 and very fine force sensing.
Quick verdict. The UR5e is the better general-purpose choice, with 5 kg payload, ±0.03 mm repeatability and the UR+ ecosystem. The Flexiv Rizon 4 + F/T Sensor is the better choice for delicate contact tasks, with 0.03 N force sensing accuracy, 7 axes and IP65.
UR5e and Rizon 4 + F/T Sensor at a glance

Price comparison
UR5e: listed from $35,000
Flexiv Rizon 4 + F/T Sensor: listed from $35,000
Difference: none at list price
At the same listed price, the decision rests on payload, precision and force sensing.
Payload, reach and precision
The UR5e carries 5 kg, 1 kg more, and publishes ±0.03 mm repeatability against ±0.05 mm. The Rizon 4 + F/T Sensor reaches 919 mm, about 69 mm more, and its 7 axes help it work around fixtures while keeping the tool orientation.
Force sensing
Flexiv publishes 0.03 N force sensing accuracy and a 150 N maximum TCP force for the Rizon 4 + F/T Sensor. That suits polishing, connector mating and delicate insertion. The UR5e's built-in 50 N / 10 Nm force/torque sensor covers standard screwdriving, insertion and part detection.
Protection, weight and controller
The Rizon 4 + F/T Sensor is rated IP65 and runs on the 12 kg Flexiv Hesper controller. The UR5e weighs 20.6 kg, about the same as the 21 kg Rizon arm, and has 17 configurable safety functions with PolyScope programming.
