Universal Robots UR3e Collaborative Robot

1. Product Overview

The UR3e is the most compact and lightweight collaborative robot (cobot) in the Universal Robots e-Series lineup. With a payload capacity of 3kg, a reach of 500mm, and a weight of only 11.2kg, it offers repeatability of ±0.03mm, making it an ideal solution for precision tasks in confined spaces.

Unlike traditional industrial robots, the UR3e is designed for flexibility and safety:

• It can be deployed directly on workbenches, in labs, or small automation cells without requiring large safety fences.
• Its intuitive, graphical programming interface allows operators to configure tasks within minutes, dramatically lowering the barrier to automation.
• As a member of the e-Series family, the UR3e features an integrated force-torque sensor and enhanced safety functions, making it suitable for electronics assembly, light screwdriving, precision testing, and laboratory automation.

UR3e’s design philosophy is “flexible, efficient, user-friendly”, delivering high return on investment (ROI) and empowering SMEs to upgrade to automation cost-effectively.
