The UR5e costs roughly 11% less
Payload and reach
The Link 6 carries 6 kg continuously across its full range and reaches 1149 mm, 299 mm more than the UR5e. Every joint rotates through ±360°, and the arm mounts in any orientation. Wider machine-tending and packaging layouts favor the Link 6.
Precision and speed
The UR5e publishes ±0.03 mm repeatability against ±0.1 mm for the Link 6. Kinova publishes a 2.0 m/s maximum TCP speed. Precise assembly, insertion and screwdriving favor the UR5e.
Sensing, controller and ecosystem
The UR5e has a built-in 50 N / 10 Nm force/torque sensor and 17 configurable safety functions, and runs PolyScope with UR+ accessories. The Link 6 runs on its own controller with an Intel Core i7, 8 GB RAM and a 128 GB SSD, sealed to IP54 like the arm.
