The UR3e is a lightweight collaborative industrial robot produced by Universal Robots. Here are the key features of this robot:
- **Appearance and Dimensions**: The UR3e is the smallest industrial collaborative robot arm in the Universal Robots product line, weighing only 11.2 kg with a payload capacity of 3 kg. Its small footprint, at just 128 mm, makes it suitable for use in narrow workspaces, such as on desktops or inside production machinery.
- **Technical Specifications**: The UR3e has 6 degrees of freedom with rotating joints and a working radius of 500 mm. Its control box has an IP44 protection rating, suitable for operation in environments with up to 90% humidity, non-condensing.
- **Performance**: With a payload of 3 kg and a working radius of 500 mm, the UR3e is compact and well-suited for tight workspaces. It is equipped with 17 configurable safety features and is certified to EN ISO 13849-1 and EN ISO 10218-1 PLd Category 3 standards.
- **Control and Programming**: The UR3e is programmed using a 12-inch touch screen and features the polycope graphical user interface.
- **Additional Features**: The control box dimensions are 460 mm x 449 mm x 254 mm, weighing 12 kg. The tool (end effector) connector type is M8 M8 8-pin, with a cable length of 4.5 meters.
The UR3e, with its compact size, lightweight design, and powerful capabilities, has become an integral part of automated production environments. It is designed to work alongside human workers, enhancing productivity and ensuring safe collaboration.

The UR3 and UR3e are two different models of collaborative robots produced by Universal Robots, and there are some key differences between them:
1. **Design and Functional Improvements**: The UR3e is an upgraded version of the UR3, featuring a more lightweight design, including an 8mm cable, which makes the robot's operation more flexible and precise. Additionally, the teach pendant design of the UR3e has been improved for easier operation.
2. **Control and Repeatability Accuracy**: The UR3e boasts a repeatability accuracy of 0.03mm, thanks to its 500 Hz control frequency, which is four times faster than the CB3 series.
3. **Safety Features**: The UR3e is equipped with elbow joint safety features, allowing for the setting of force, speed, and boundary limits, thus enhancing operational safety.
4. **Tool Endpoint Interface**: The UR3e's tool endpoint supports RS-485 communication, simplifying cable routing, especially in applications requiring three-prong grippers.
5. **Joint Replacement**: The UR3e allows for easier joint replacement, taking only 10 minutes, whereas the CB3 series requires half an hour.
6. **Integrated Force and Torque Sensors**: The UR3e integrates force and torque sensors on the tool flange, enabling it to detect force impacts more sensitively and perform rapid contact detection.
7. **Automatic Calculation of Load Center of Gravity**: The UR3e can automatically calculate the center of gravity of the load, which helps to improve operational precision.
8. **Programming and Applications**: The UR3e has an improved programming process, making it easier for the robot to perform complex tasks such as stacking and path importing.
In summary, the UR3e offers more advanced features and optimized performance compared to the UR3, particularly in terms of repeatability accuracy, control frequency, safety features, and programming capabilities.
