UR20 vs AUBO-i20: 20 kg Cobot Comparison of Price, Reach and Protection
The Universal Robots UR20 and the AUBO-i20 are 20 kg cobots of almost identical weight and the same ±0.1 mm repeatability. The UR20 reaches a little further, moves much faster and is protected to IP65. The AUBO-i20 costs about half as much.
Quick verdict. The AUBO-i20 is the value choice for palletizing and heavy handling, with a listed price about 50% lower and broad SDK support. The UR20 is the better choice for high-throughput and harsh-environment cells, with 100 mm more reach, a 5 m/s speed and IP65.

Price comparison
UR20: listed from $72,100
AUBO-i20: listed from $36,300
Difference: $35,800
The AUBO-i20 costs roughly 50% less
For multi-line palletizing, a saving of this size per robot is significant.
Payload and reach
Both robots carry 20 kg and repeat to ±0.1 mm. The UR20 reaches 1750 mm, 100 mm more than the AUBO-i20, which helps with taller pallet stacks.
Speed and protection
Universal Robots publishes a 5 m/s maximum tool speed for the UR20 and rates it IP65 and ISO Class 4. That suits high-throughput palletizing and wet or dusty end-of-line areas.
Sensing and connectivity
The UR20 has a built-in ±200 N / ±20 Nm force/torque sensor and supports PROFINET with PROFIsafe, EtherNet/IP, Modbus TCP and ROS/ROS2. AUBO publishes TCP/IP, Modbus RTU/TCP, PROFINET, ROS and SDKs for C/C++, C#, Lua and Python for the i20.
Best applications for the UR20
