UR3e vs Elephant Robotics Catbot: 3 kg Cobot Comparison of Price and Precision
The Universal Robots UR3e and the Elephant Robotics Catbot both carry 3 kg, at very different prices. The Catbot, sold as the C3, is an all-in-one arm with the controller inside the robot body and costs about 83% less. The UR3e repeats more tightly, is lighter and has a full industrial feature set.
Quick verdict. The Elephant Robotics Catbot is the low-cost choice for light tasks, pilots and education, with 600 mm reach, an integrated controller and a listed price of $5,900. The UR3e is the better choice for production work, with ±0.03 mm repeatability, a 3 m/s tool speed, a force/torque sensor and documented safety functions.
UR3e and Elephant Robotics Catbot at a glance
The UR3e carries 3 kg over 500 mm, repeats to ±0.03 mm and weighs 11.2 kg.
The Elephant Robotics Catbot carries 3 kg over 600 mm, repeats to ±0.05 mm and weighs 18 kg including its integrated controller.

Price comparison
UR3e: listed from $33,800
Elephant Robotics Catbot: listed from $5,900
Difference: $27,900
The Catbot costs roughly 83% less
At this gap, several Catbots cost less than one UR3e, which changes the economics for simple, repetitive tasks.
Reach and precision
Both arms carry 3 kg. The Catbot reaches 600 mm, 100 mm more. The UR3e publishes ±0.03 mm repeatability against ±0.05 mm, which matters for precise electronics assembly and insertion.
All-in-one design
The Catbot integrates its control electronics in the robot body, so there is no separate cabinet to mount or cable. That simplifies small cells and mobile setups. The UR3e uses a separate control box and weighs 11.2 kg, against 18 kg for the complete Catbot.
Industrial features
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 support, with UR+ accessories. Those features matter in production cells with safety and integration requirements.
