About the UFACTORY 850
The UFACTORY 850 is the heavy-duty member of the xArm family, built for users who need more reach and payload than desktop arms can offer while keeping the affordability and ease of use the brand is known for. With a 5-kilogram payload and an 850-millimeter reach, it comfortably handles machine tending, palletizing of light boxes, packaging, dispensing, and multi-station material transfer in small factories. The arm retains full 6-axis dexterity and plus or minus 0.1-millimeter-class repeatability, so precision does not suffer as the working envelope grows. Programming remains accessible through xArm Studio’s graphical interface, hand-guided teaching, and Python or ROS integration, allowing one technician to manage deployment without specialist training. Collision detection supports collaborative operation, and the robust aluminum construction tolerates continuous duty cycles on busy production lines. For small and medium manufacturers priced out of traditional industrial robots, the 850 delivers a practical bridge: genuine production capability, a broad accessory ecosystem, and total ownership costs that make automation projects financially viable.

CNC Machine Tending Operations
Small machine shops use the 850 to load and unload CNC mills, lathes, and engraving machines across lights-out shifts. Its 850-millimeter reach spans the distance between a parts table and machine door, while the 5-kilogram payload handles most small-to-medium workpieces and fixtures. Programs are taught by hand in an afternoon, and the arm can signal machine start through simple IO connections, letting one operator supervise several machines instead of standing at a single station.
End-Of-Line Packaging And Palletizing
Food producers and consumer goods workshops deploy the 850 at the end of packaging lines to stack cartons, arrange products in trays, and build light pallets. The generous reach covers standard pallet footprints at low stack heights, and quick gripper changes let the same cell handle different product sizes across a week. The modest investment makes automation practical even for seasonal producers who previously relied entirely on manual packing labor.
Dispensing And Gluing Applications
Manufacturers of electronics, lighting, and consumer products use the 850 for adhesive dispensing, sealant application, and coating tasks along complex paths. The arm’s repeatability keeps bead placement consistent across thousands of parts, reducing waste and rework. Path programming through hand guidance is faster than offline programming for short runs, and the Python API allows integration with dispensing controllers that synchronize flow rate with arm speed.
Multi-Station Material Transfer
Growing factories position the 850 between workstations to transfer parts between assembly, inspection, and packaging areas. Its reach covers several stations from a single mounting point, reducing conveyor requirements. Vision accessory support enables the arm to locate parts presented with some variation, and collision detection lets it share space with workers, making it a flexible logistics helper that adapts as the production layout evolves.
Frequently Asked Questions
What is the payload of the 850?
The UFACTORY 850 is rated for a 5-kilogram payload at full extension. This capacity covers most small cartons, machined workpieces, dispensing tools, and multi-finger grippers with parts, making it suitable for machine tending, packaging, and light palletizing work.
How far can the 850 reach?
The 850 provides a maximum reach of 850 millimeters from its base mounting point. This extended envelope allows it to serve CNC machine doors, pallet stations, and multi-station setups that smaller desktop arms cannot span from one fixed position.
Can the 850 run continuously?
Yes, the 850 is built with continuous-duty components and an industrial-grade structure suited to multi-shift operation. Regular maintenance per the manual, appropriate duty-cycle planning for extreme speeds, and a clean environment help maximize service life in demanding production schedules.
Is programming difficult for beginners?
No, beginners can create programs using the graphical xArm Studio interface or by physically guiding the arm through the desired motions with drag teaching. These methods require no coding knowledge, while Python and ROS remain available as skills and requirements grow.
Does it work with vision systems?
Yes, the 850 integrates with UFACTORY’s camera accessories and with third-party vision systems through the Python SDK and ROS interfaces. Typical setups locate parts on conveyors or trays, correct pick positions automatically, and verify placement, greatly improving robustness in real factory conditions.
What safety features are included?
The 850 includes collision detection that stops the arm upon unexpected contact, configurable speed limits, and emergency-stop integration through its controller. A site-specific risk assessment remains essential, and additional guarding or scanners can be added where the application demands higher protective levels.
How does it compare to industrial arms?
The 850 trades the extreme speed, payload, and certified safety ratings of premium industrial cobots for a dramatically lower price and simpler software. For small manufacturers with moderate throughput requirements, it delivers most of the practical value at a fraction of the investment.
What mounting options are supported?
The 850 mounts on benches, pedestals, machine frames, or mobile carts using its standard base flange. The controller communicates over Ethernet, so the arm can be integrated into existing lines, and customers often build custom stands matched to their specific station heights.
