UFACTORY Lite 6 Cobot

Applications

The Lite 6 is primarily aimed at small-scale automation and robotics development where compact size matters more than high payload or long reach. UFACTORY highlights lab automation and robotic research as two of its main applications, alongside coffee-machine operation and touchscreen or keyboard testing. Its 600 g payload makes it most appropriate for lightweight objects, tools and test equipment rather than heavier industrial handling.

Its six axes still provide the motion flexibility expected from a conventional articulated robot arm, while the 440 mm reach keeps the overall working envelope relatively compact. Pick-and-place is another natural application, particularly when the robot is paired with UFACTORY's Gripper Lite or Vacuum Gripper Lite. The open Python/C++ development tools and ROS/ROS2 support also make the Lite 6 useful as a physical platform for robotic control, perception, automation and research projects where a full-sized industrial cobot would be unnecessary.

What Makes the Lite 6 Special

The main distinction of the Lite 6 is that UFACTORY has packaged a six-axis collaborative robot into a relatively small, self-contained tabletop platform. The robot weighs 8 kg, has a 130 × 140 mm footprint and incorporates its controller into the robot rather than requiring the separate control box used by UFACTORY's larger xArm models.

That makes the Lite 6 particularly interesting where bench space, portability and straightforward deployment matter. Programming can be done through the browser-based UFACTORY Studio interface, including graphical drag-and-drop programming, while more advanced users can work through Python, C++, ROS or ROS2. Hand teaching provides another way to establish robot motion for suitable applications.

There is a clear trade-off for the smaller format: its 600 g payload, 440 mm reach and ±0.5 mm repeatability are considerably below UFACTORY's larger xArm and 850 cobots. Lite 6 is therefore best viewed as UFACTORY's compact, lightweight option rather than a smaller replacement for its higher-performance industrial cobots.

Lite 6 vs Other UFACTORY Cobots

Lite 6 is the smallest and lightest cobot in UFACTORY's current range. It offers a 440 mm reach, 600 g payload, ±0.5 mm repeatability and an 8 kg robot weight. The xArm series steps up to a 700 mm reach, 3–5 kg payload and ±0.1 mm repeatability, with 5-, 6- and 7-axis versions available; these robots are better suited when greater payload, reach or motion capability is required.

The UFACTORY 850 moves further toward industrial performance, providing an 850 mm reach, 5 kg payload and ±0.02 mm repeatability, although the robot itself weighs 20 kg. Unlike Lite 6's integrated controller, the xArm and 850 use separate control boxes.

In simple terms, Lite 6 is the compact tabletop choice, xArm provides the broadest balance of size, payload and axis configurations, and the 850 is the higher-reach, higher-precision option for more demanding automation.
