UR3e
UR3e is the smallest member of the e‑Series family, purpose-built for tasks that happen directly on the workbench. The 3 kg payload and 500 mm reach make it a natural fit for screwdriving, light assembly, testing, and laboratory work, while its very low weight allows the robot to be moved between stations when needed. Despite its compact size, UR3e includes the same force sensing, safety functions, and programming interface as the larger models, so skills and programs transfer seamlessly across the range.

Frequently Asked Questions
UR3e shines in tasks that happen right on the bench: driving screws, assembling small parts, loading test fixtures, and handling light components where reach requirements are modest but precision is important.
Yes. Because the arm weighs just over ten kilograms and has a small base, it is practical to mount it on mobile carts or plates and relocate it as production needs change.
UR3e includes an integrated force/torque sensor, allowing it to feel contact forces and execute tasks such as press-fitting, polishing, or gently seating parts into fixtures.
Most simple tasks can be taught using the touch interface and by physically guiding the robot through the desired path, so operators can get started after brief training without writing code.
The robot is designed for collaborative applications, but whether fences can be removed depends on a risk assessment that considers the specific tool, part, and motion speeds used.
UR3e runs from standard AC mains and typically draws about the same power as a small household appliance during normal operation.
