UFactory −10% in March: Lite 6, xArm, 850

UFactory in March (−10%): three robotic arms, three complementary profiles — Lite 6, xArm, 850

  • March 2nd 2026

For labs, innovation hubs, R&D teams, and education: a simple guide to easily choose between Lite 6, xArm, and 850, and match the right end-effector (gripper or vacuum) to your tasks.

Key takeaways

  • The UFactory lineup is compact: Lite 6, xArm, and 850 correspond to three different profiles, designed for distinct use cases.
  • For reliable deployment, the choice isn’t only about the arm: the end-effector (gripper or vacuum) strongly influences the success rate.
  • In many projects, the best compromise is to start with a simple arm + end-effector combination, then adjust based on tasks and context (additional sensors, structures, complementary robotic platforms).
  • In March, a −10% discount applies to the UFactory range (arms and accessories).

Why a short product range can be an advantage?

In laboratories, R&D, and education, the challenge isn’t making a robotic arm work once.

The challenge is to:

  • Achieve repeatable results
  • Maintain them over time
  • Transfer them to other users (technicians, PhD students, students, engineers)

When a range is easy to understand, it becomes simpler to choose a suitable model without ending up with something too complex for the real need—or wasting time on options that don’t change the outcome.

Two factors to consider before choosing

1) Gripper or vacuum: choose the right end-effector

Gripper (claw/gripper)

Prefer if:

  • Objects are irregular, not flat, or variable
  • You want a grip that is more tolerant of uneven, dusty, or textured surfaces
  • There is high part diversity (teaching, demos, iteration)

Vacuum (suction)

Prefer if:

  • Objects are mostly flat (boxes, bags, sheets, smooth surfaces)
  • Surface condition is controlled (smooth, low-porosity, relatively clean)
  • Pick speed matters—on a compatible object (flat and smooth surface)

Rule of thumb: if you’re not yet sure what objects will be handled, start with a gripper. Suction is very effective, but more dependent on surface type (flat, smooth, and clean).

2) Clarify the goal: flexibility or repeatability

Flexibility

You are testing multiple scenarios, changing objects and tools, and regularly adjusting trajectories.

Repeatability

You want stable behavior for a protocol (test bench, calibration, data acquisition, measurable demonstration).

This distinction often points to the xArm when you need flexibility to experiment, or to the uFactory 850 when you want highly repeatable results.

The Lite 6 is especially well-suited to learning and training, as well as setups with a small footprint (workbench, lab table, teaching bench).

uFactory: a compact and complementary range

1) Lite 6: ideal for education, training, and small spaces

When to choose it

  • Practical lab sessions, demonstrations, educational workshops
  • Compact workbench station, need for quick start-up
  • Projects where the goal is to learn, test, then progressively automate

Arm + end-effector (depending on your objects)

  • Lite 6 + Gripper for Lite 6 : recommended if objects aren’t perfectly flat, or if you want a more tolerant mechanical grip.
  • Lite 6 + vacuum pump for Lite 6 : recommended if objects are flat and compatible with suction (clean, smooth).

Watch point: with suction, testing on real objects is important → a slightly porous or dusty surface can reduce the success rate.

2) xArm: flexibility for innovation hubs and R&D teams

When to choose it

  • Exploratory projects and rapid iterations
  • Varied objects and tooling that will change
  • Need for a versatile platform for multiple scenarios

Arm + end-effector (depending on your objects)

  • xArm + gripper G2 for xArm : often the most robust choice when objects vary and you want a highly versatile mechanical grip.
  • xArm + Vacuum gripper for xArm : very effective on flat or packaged objects if surface condition is controlled.

Watch point: as soon as multiple people use the station, document key parameters (speeds, limits, trajectories, grip settings). That’s often where results become harder to reproduce.

3) UFactory 850: precision and repeatability for benches and protocols

When to choose it

  • Test benches & measurements: execute the same motion to compare results (forces, positions, cycle time, grip quality) or repeatedly test a tool/sensor.
  • Measurable demos: when you must show stable outcomes (same trajectory, same accuracy, same success rate).
  • Calibration & data acquisition: repeat trajectories to record data (camera, force/torque sensor, encoders, external sensors) with minimal session-to-session variation.
  • Test-bench setups: rigid and repeatable mounting (same clamping, same contact points), controlled cable routing, and periodic reference checks to ensure comparable measurements.

Arm + end-effector (depending on your objects)

  • 850 + gripper G2 for xArm : for versatile mechanical gripping on standard objects.
  • 850 + BIO Gripper G2 for 850 : consider if your context requires more delicate handling or specific objects (validate for your application).
  • 850 + Vacuum gripper for xArm : relevant if objects are flat and compatible with suction (smooth, low-porosity, relatively clean); UFactory lists it among 850 accessories.

Watch point: as soon as multiple people use the station, document key parameters (speeds, limits, trajectories, grip settings). That’s often where results become harder to reproduce.

Frequently asked questions

Because the end-effector often determines the real success rate. A good arm with an unsuitable grip leads to an unstable setup.

When objects are porous, dusty, highly textured, irregular, or when surface conditions aren’t controlled. In these cases, a gripper is often more forgiving.

By locking software versions, saving critical parameters (frames, limits, speeds), and keeping a simple reference test to verify behavior after each change.
