UR3e
About
About UR3e
UR3e is a six-axis arm built for benchtop cells, test stations and machines with limited surrounding space. Joint torque sensing and configurable safety functions support collaborative deployment following application assessment, while the compact wrist can carry grippers, screwdrivers, dispensers and inspection sensors. Its small base allows the robot to be mounted on tables, mobile carts or directly beside production equipment.
Users program the arm through Universal Robots’ PolyScope interface and can extend applications through URCaps supplied by tooling and software partners. Integrated I/O and industrial communications connect the robot to machines, fixtures and cell controls. UR3e is sold through Universal Robots’ distributor and integrator network for assembly, laboratory automation, electronics handling, testing and light machine tending.
Capabilities
Source-backed capabilities
- Robotic grasping
Research demonstration - 2025-12-31 - In this work, we address the limitation of surface fitting-based grasp planning algorithm, which primarily focuses on geometric alignment between the gripper and object surface while overlooking the stability of contact point distribution, often resulting in unstable grasps due to inadequate contact configurations.
Source - Precision insertion
Research demonstration - 2025-12-03 - ContactRL validates tactile reinforcement learning for contact-rich insertion on a physical Universal Robots UR3e arm.
Source - Object manipulation
Research demonstration - 2024-11-18 - TrojanRobot studies physical-world backdoor attacks against robotic manipulation policies.
Source - Remote and shared control
Research demonstration - 2025-04-02 - The study proposes a real-time shared-control framework for active 3D scene representation in robotic inspection.
