UR3e vs DOBOT CR3L: 3 kg Cobot Comparison of Reach, Price and Availability
Both the Universal Robots UR3e and the DOBOT CR3L carry 3 kg, but they suit very different cells. The CR3L is the long-arm version of the DOBOT CR3, with a 1700 mm reach, and costs about a third less. The UR3e is a compact, current model with fully documented precision, speed and protection data.
Quick verdict. The DOBOT CR3L is the better fit for light handling across a large area, with 1700 mm reach and a listed price about 34% lower, but it is no longer part of the current DOBOT range. The UR3e is the better choice for compact production cells, with ±0.03 mm repeatability, an 11.2 kg arm, a built-in force/torque sensor and long-term support.

UR3e: listed from $33,800
DOBOT CR3L: listed from $22,200
Difference: $11,600
The CR3L costs roughly 34% less
Reach and working area
The CR3L reaches 1700 mm, more than three times the UR3e's 500 mm. DOBOT built it for light assembly, inspection and pick-and-place that need more reach than the standard CR3. One CR3L can serve a wide conveyor or several stations; the UR3e is sized for a single bench or inside a machine.
Availability and support
The CR3L is no longer part of the current DOBOT product range; the CR series has been succeeded by the CRA series. Spare parts and long-term support should be checked before buying. The UR3e is a current model with the UR+ ecosystem and a wide integrator base.
Interfaces and features
The CR3L lists TCP/IP, Modbus TCP, Wi-Fi, EtherCAT, an RS485 tool interface and 16 digital inputs plus 16 configurable digital I/O. The UR3e has a built-in ±30 N / ±10 Nm force/torque sensor, a 3 m/s maximum tool speed, IP54 and PROFINET with PROFIsafe, EtherNet/IP, Modbus TCP and ROS/ROS2.
