§9 xArm 6
What the machine cannot do, and the figures the UFACTORY sources do not give.
This section says what the machine cannot do and where it must not be used: the limits you work within, the places where UFACTORY's own documents disagree, and the figures the UFACTORY sources do not give.
S6 in one line: S6 is the xArm 6 cobot that handles parts after processing, routing them to inspection, rework or shipping6.
A question from earlier on, to keep it fresh. Skip it if you like; nothing depends on it.
Choose your depth
1Beginner
For: Anyone with no robotics background: a visitor, a new operator, a manager
Kind of task: Recognise and recall, with plain-language explanations and pictures
In this part you learn how much the arm can carry, where it may be used, and why the word "cobot" does not make it safe to stand beside. No robotics background is needed.
Answer, then check. Each option has its own feedback, and nothing is scored.
2Novice
For: Someone who will work near or with the cell: operator, trainee technician
Kind of task: Explain and sequence: put steps in order, match parts to their functions
In this part you learn the space the arm can reach, where it moves badly, the rest of the conditions it is rated for, and the limits on its cables and its software. It is for someone who will work near or with the cell.
Answer, then check. Each option has its own feedback, and nothing is scored.
3Intermediate
For: Someone who will set up, program or maintain the arm: technician, student engineer
Kind of task: Apply: work through written scenarios that need a decision (which mode, which setting, what to do about this error), with feedback on each choice
In this part you learn the limits you meet when you program and look after the arm: what its precision figure covers, the moves the controller refuses, why the firmware and serial number of a particular arm matter, what the manual gives for maintenance, and where UFACTORY's own documents disagree. It is for someone who will set up, program or maintain the arm.
Answer, then check. Each option has its own feedback, and nothing is scored.
4Expert
For: Someone who designs, integrates or changes the cell: integrator, engineer, agent developer
Kind of task: Analyse and decide: weigh trade-offs, resolve contradictions, critique a configuration
In this part you sort the machine's limits by what they constrain: an engineering estimate, a safety argument, or the way a program commands the arm. The interfaces section covers the settings an agent could change and the limits of Studio's simulated arm. It is for someone who designs, integrates or changes the cell.
Answer, then check. Each option has its own feedback, and nothing is scored.
What the sources do not settle for this section. Nothing here is papered over with a plausible number.
UFACTORY sources give different joint ranges for the xArm 6. The xArm manual (section 8.3 and the Preface) gives J2 as -117° to 116° and J3 as -219° to 10°; the Studio manual's specifications table gives J2 as (-118, 120) and J3 as (-255, 11) for the xArm6.
See reference 4No chapter of the xArm manual (Preface and chapters 1 to 8) and nothing on the xArm product page gives an IP (ingress protection) rating for the xArm 6 or its Control Boxes. The manual refers only to 'non-waterproof equipment' and to keeping water and dust out.
See reference 5No IP (ingress protection) rating for the xArm 6 arm or its control boxes was found in the manual or the product page. The manual instead warns that the arm and its hardware must not be in direct contact with liquid, and to keep non-waterproof equipment dry.
See reference 11UFACTORY's xArm product page presents the xArm as a collaborative robot ('cobot'), while the xArm manual says no people or other equipment should be in the working area when the arm is in operation. Neither source says how the two fit together.
See reference 12No fetched UFACTORY source gives an absolute positioning accuracy for the xArm 6 (how closely it reaches a computed coordinate, as opposed to its ±0.1 mm repeatability). This matters for offline programming and vision-guided picking, which rely on computed coordinates.
See reference 29The xArm manual's Maintenance and Inspection chapter covers only long-term storage charging and cleaning. No chapter of the fetched manual gives an inspection interval, a lubrication schedule, a brake test or a service life for any part; chapter 1 says only to check the bolts 'regularly'.
See reference 36No fetched UFACTORY source gives a public known-issues list for current xArm firmware. Release notes list fixes only after the fact, such as the V2.7.0 zero-speed fix, so open defects in the installed firmware cannot be checked.
See reference 39No fetched UFACTORY source gives cycle-time data for the xArm 6, or the speed and acceleration it reaches while carrying its full 5 kg payload across its reach; the payload versus TCP offset relationship is published only as a figure.
See reference 40The xArm manual says the payload is related to the TCP offset, but its text gives no payload-versus-offset values; the xArm 6's allowable payload at a given tool offset could not be taken from the sources as text.
See reference 41No fetched UFACTORY source gives a design life, MTBF or harmonic-drive service life for the xArm 6; the only durability figure is the product page's 15,000-hour stress test.
See reference 42No chapter of the xArm manual (Preface and chapters 1 to 8), the xArm product page or the Studio manual states an ISO 13849-1 Performance Level or Category, or an IEC 62061 SIL, for any xArm safety function (emergency stop, EI/SI inputs, collision detection, safety boundary or reduced mode), and none mentions a TÜV certification. Do not assume any.
See reference 43No fetched UFACTORY source says whether the xArm 6 is suitable or validated for power and force limiting collaborative applications. No fetched UFACTORY source gives contact force or pressure figures for the xArm 6, or a torque or force threshold for any collision sensitivity level.
See reference 44No fetched UFACTORY source says whether the software safety functions (collision detection, safety boundary, reduced mode) are enforced independently of the motion-command path. Studio's description of the safety boundary mentions only the tool centre point, and no source says whether the arm's links or the tool body are checked against it.
See reference 45The xArm manual gives stop data only for Stop Category 1 and Joints 1 to 3, in one configuration (fully extended, 100% speed, 5 kg payload), and does not say which arm model was measured. No data was found for Joints 4 to 6, for other speeds or payloads, for Stop Category 2 (the SI safeguard stop), or for stopping after a collision is detected. These are needed for any separation-distance calculation at S6.
See reference 46The xArm manual describes the Control Box emergency stop in ways that do not fit together. Section 2.1.2 says the arm's power supply is removed within 300 ms and that pressing the button powers off the xArm; section 3.2.2 says the button allows the user to cut off the arm's power in the shortest time possible. Section 7.9 says the same button is Stop Category 1, which decelerates the robot 'with drive power on', and section 7.10 gives Stop Category 1 stopping times of 521 to 885 ms. The manual does not explain how power removal within 300 ms fits a powered deceleration lasting up to 885 ms.
See reference 48Per-joint component data for the xArm 6 (motor model and rating, harmonic-drive ratio, encoder type and resolution, joint-module sizes) is not published in the xArm manual or the product page; the product page names only harmonic drives and servomotors and, unlike the 850's page, gives no encoder resolution.
See reference 61No dedicated teach pendant for the xArm 6 is documented in the xArm manual or the product page: they describe programming through the browser-based UFACTORY Studio, the SDKs and hand teaching.
See reference 62No Ethernet connection, camera port, force-torque sensor interface or user button at the xArm 6's tool end is described in the xArm manual or the product page; the product page lists the end-effector I/O as 2 DI, 2 DO, 2 AI and 1 RS-485.
See reference 63No specification for the BIO Gripper G2, the 6-axis force/torque sensor or the linear motor (payload, force range, resolution, stroke) was found in the xArm manual or the product page; only their names are listed.
See reference 64Sources disagree on how the xArm AC control box powers the arm: the manual's controller chapter says its internal supply converts 100-240 V AC into 12 V and 48 V DC for the control box and the arm, while the common specification table gives the arm's input as 24 V DC, 20.8 A and the AC controller's output as 24 V DC, 20.8 A.
See reference 65What tool inputs TI2-TI4 and outputs TO2-TO4 are on the xArm 6 is not documented: UFACTORY Studio lists TI0-TI4 and TO0-TO4, but the xArm manual's tool connector defines only TI0, TI1, TO0 and TO1.
See reference 66Whether the xArm 6 has an Ethernet connection at the end flange is not answered by the sources fetched: the xArm manual's Robotic Electrical Interface chapter has an 'End Flange' heading with no text, and its tool I/O pins carry no Ethernet.
See reference 67Sources disagree on the xArm end-effector communication protocol: the online xArm manual's common specification table (and its Gripper table) say Modbus TCP, while the xArm Developer Manual's common specifications and gripper table say Modbus RTU, and the online manual's own Tool RS485 section configures standard Modbus RTU devices.
See reference 68The physical I/O that will carry signals between S2 and S4 (and the other stations) is not defined. It may differ from the simulation's signals.
See reference 69The future 3D-printed flow in the IntelliMake diagram has no S2 step (printed parts go from S7 straight to S6), but the owner states S2 will handle material for 3D printing in the future. What S2 does in the future flow is unresolved.
See reference 70Cycle times for S2's moves (S1 to S4, S1 to S3, S3 to S4) and for the S4/S5 laser step are not documented, so throughput and the benefit of two arms cannot be quantified.
See reference 71The end effector fitted to S2 (the gripper or suction tool used for business cards) is not documented.
See reference 72The number and positions of allocated S3 staging slots are not documented. The diagram's illustration shows six pads on the table, but it is a drawing, not a specification.
See reference 73The layout draws unlabelled return paths from the laser and S6 region back toward S1 and S2. Whether reworked parts re-enter through S1 or S2, and what S2 does in rework, is not documented.
See reference 74IntelliMake's reason for using two arms, and for putting the 850 at S2 and the xArm 6 at S6, is not documented in any source available to this project (Q14d).
See reference 75The project specification describes S6 as the downstream arm that handles parts after processing, but IntelliMake's future 3D-printed flow has S6 handling parts before laser engraving (S7 → S6 → S4/S5). S6's role is therefore not simply 'after processing' in the future flow.
See reference 76S2's current, as-built automation level in the physical cell is not documented. Level 5E is this project's target (int-041), not a description of the cell today (Q14c).
See reference 77No fetched UFACTORY source announces future xArm 6 hardware: no successor model, published product roadmap or end-of-life date.
See reference 78As published, the xArm manual's 'Limitation of Liability' section says safety information 'must be construed as a warranty by UFACTORY' that the xArm will not cause injury or damage even if all safety instructions are complied with. That wording sits under a heading about limiting liability, and no fetched source says what UFACTORY intended. Do not read it as a guarantee of safety.
See reference 79UFACTORY sources disagree on the collision sensitivity range. Studio's Settings page says levels 1 to 5; Studio's glossary and the Python SDK say 0 to 5, and the glossary says 0 disables collision detection. A learner reading only the Settings page would not learn that the value can switch detection off.
See reference 80The EMC standards the xArm manual lists do not match the EMC verification it links. Section 7.2 lists EMC 2004/108/EC, EN 61000-6-2:2005 and EN 61000-6-4:2007+A1:2011 as the standards the xArm 6 meets. The linked SGS EMC verification names EN IEC 61000-6-2:2019 and EN IEC 61000-6-4:2019 under Directive 2014/30/EU. Section 7.3 lists both the older editions and the 2019 editions without saying which apply.
See reference 81The xArm manual's Preface and Hardware Installation chapter say they apply to models XF1305, XI1305 and XS1305, and the linked RoHS certificate lists those numbers among others. The linked SGS machinery and EMC verifications name models XI13 and XI15. No fetched text says whether XI13 and XI15 cover the 1305 models, or which model number is on the S6 xArm 6's label.
See reference 82The xArm manual says the arm will 'slightly brake and fall' when the emergency stop is pressed, but no fetched source says how far it may fall, at which joints, or how long the brakes take to engage.
See reference 83No fetched UFACTORY source gives an explicit intended-use or reasonably foreseeable misuse statement for the xArm 6, beyond the environmental conditions and the general warnings in chapter 1.
See reference 84No fetched UFACTORY source identifies specific pinch or crush points on the xArm 6, such as between links or at gripper fingers.
See reference 85The EU Declaration of Conformity for the xArm 6 was not found. The manual says the xArm 6 has passed EU CE certification, and both SGS verifications say the CE mark can be affixed or used, under the responsibility of the manufacturer, after completion of a Declaration of Conformity.
See reference 86The S6 xArm 6's controller type (AC or DC), serial number, firmware, Studio and SDK versions are not confirmed. The serial number matters because UFACTORY treats arms before XX1300 differently for friction parameters and the IMU mounting check, and firmware decides which SDK safety calls are available.
See reference 87Sources disagree on the xArm 6's weight: 12.5 kg (arm only) in the online hardware manual and the product page's comparison table, but 12.2 kg (body only) in UFACTORY's support article comparing the xArm 5 Lite, 6 and 7. The product page's introduction also says '15kg weight' without naming a model.
See reference 88Sources disagree on the range of the xArm 6's joint 2 (J2): the online hardware manual (specifications and preface) and the product page give -117° to 116°, but UFACTORY's support article comparing the xArm 5 Lite, 6 and 7 gives -118° to 120°, and the xarm6 URDF's default limits are -2.059 to 2.0944 rad (about -118° to 120°).
See reference 89Sources disagree on the range of the xArm 6's joint 3 (J3): the online hardware manual (specifications and preface) and the product page give -219° to 10°, but UFACTORY's support article comparing the xArm 5 Lite, 6 and 7 gives -225° to 11°, and the xarm6 URDF's default limits are -3.927 to 0.19198 rad (about -225° to 11°).
See reference 90The xArm manual disagrees with itself on what the AC control box supplies: its specification table (and the product page) give the AC controller's output as 24 V DC, 20.8 A, but its 3.2.2 Power Supply text says the internal switching power supply converts 100–240 V AC into 12 V and 48 V DC, which powers the control box and the robotic arm.
See reference 91No dimensioned base or tool-flange drawing values for the xArm 6 (bolt size and count, hole pattern, bolt torque, base height) were captured as text: the manual's 'Robot Base Mounting' section and the product page's 'Robot base mounting (mm)' and 'Robot tool head' drawings are images only.
See reference 92The xArm 6's working range (workspace envelope) is given only as figures: the manual's 'Define Working Space' section and the product page show drawings, and the product page says its working-range diagrams are only for safety assessment. No workspace dimensions beyond the Cartesian range and the 700 mm reach were captured as text.
See reference 93The xArm manual gives two lower limits for the AC control box's mains input: 100 V in its specification table and power-supply section, but 110 V in its installation steps ('AC (110V-240V)').
See reference 94Sources disagree on the xArm's end-effector communication protocol: the manual's common specification table says Modbus TCP, but the product page says Modbus RTU over RS-485, and the manual's own Tool RS485 section configures standard Modbus RTU end effectors. The manual's Gripper table likewise pairs RS-485 communication with a 'Modbus TCP' protocol.
See reference 95The xArm manual's list of applied standards does not include ISO/TS 15066; no statement of ISO/TS 15066 conformance for the xArm 6 was found in the manual or the product page.
See reference 96No noise (sound pressure) figure for the xArm 6 arm was found in the manual or the product page; the only noise figure given is for the Vacuum Gripper accessory (under 60 dB at 30 cm).
See reference 97The product page lists the xArm's 'Base Connector Type' as M5*5 and does not say which connector this is; the manual's specification table does not list a base connector.

UFACTORY Studio says to set the TCP payload and TCP offset according to the actual situation. The TCP payload is the actual mass of end-effector plus object in kg, with its centre of gravity in mm in the default TCP frame at the flange centre; with virtually no load, both must be set to 0. The TCP offset gives the tool centre point's position (X, Y, Z) and orientation (roll, pitch, yaw) relative to the flange-centre frame.

The record says
Calling the xArm 6 'collaborative' does not make a given installation safe to share with people: the xArm manual says a safety assessment is required each time the arm is installed, and that a comprehensive safety assessment of the whole system should be performed when the xArm works with other machinery.
Why we infer this: UFACTORY uses 'collaborative' as a product description (app-504, app-509). The xArm manual separately requires a safety assessment for each installation and for the whole system when the arm works with other machinery. So the label describes the arm's features, not a guarantee that a particular cell allows people to work beside it.
A safety assessment is required each time installed.

Project advice
Treat the xArm 6's collision detection, safety boundary and reduced mode as configurable controller functions, not validated safeguards: they must not replace risk-assessed protective devices wired to the EI and SI inputs.
This is advice from this project, based on: safety-578 Gap safety-559 Verified safety-560 Verified safety-561 Verified safety-564 Verified safety-565 Verified safety-544 Verified
Why: No fetched UFACTORY document gives these functions a Performance Level or SIL. Collision detection is a current-model comparison that UFACTORY says can false-trigger and can be switched off; the safety boundary and reduced mode are settings. A function with no documented rating cannot stand in for a rated protective device.
Project advice
Until the S6 emergency stops, guarding, Control Box position and risk assessment are confirmed at the cell, act as though none of them exists: stay out of the xArm 6's working area while it runs, and do not rely on a safeguard nobody has confirmed.

Why: The manual says no people should be in the working area during operation, and none of the S6 safety provisions it calls for has been confirmed. Assuming they exist would put people at risk if they do not.

UFACTORY Studio says that near a singularity, planned Cartesian moves (linear, circular, but not joint moves) cannot be performed correctly and the arm stops to avoid a high instantaneous joint speed. It advises avoiding the central area near the base, and, when choosing a mounting place, considering the cylindrical volume directly above and below the base. It says moving the wrist joint close to that volume should be avoided if possible, because it makes the joints move fast even when the arm moves slowly and makes a risk assessment difficult.
When the robot performs motion planning (linear, circular, etc., excluding joint movements) near the singularity point, it will stop to avoid high instantaneous speed of the joint when it passes the singularity point.

A singularity occurs when the axes of any two joints lie on one straight line; the arm's degrees of freedom are degraded and some joints may turn too fast. Near one, planned Cartesian moves (not joint moves) stop to avoid high joint speed, so UFACTORY advises avoiding it or passing it with a joint move.

Project advice
Read the S6 xArm 6's serial number before relying on any figure the sources disagree on (weight, J2 and J3 ranges): UFACTORY distinguishes four xArm 6 versions by serial number, and the S6 arm's version decides which mass parameters apply.
Awaiting cell access: this could be confirmed or corrected once the physical S6 cell can be observed.
This is advice from this project, based on: comp-511 Verified, awaiting cell access spec-506 Contradiction, awaiting cell access spec-516 Contradiction, awaiting cell access spec-517 Contradiction, awaiting cell access
Why: The mass parameters are published per version (comp-511), so the S6 arm's version must be known to use them. The sources that disagree on weight and joint ranges (spec-506, spec-516, spec-517) do not say whether version explains the difference; knowing the version is a cheap first step, not a resolution. The serial number is on the physical arm, so this needs cell access.
The purpose of this article is to guide the user to distinguish the model of UFactory xArm by SN.

Project advice
Do not use the xArm manual's Stop Category 1 figures for S6 separation distances until UFACTORY confirms which arm and configuration they were measured on; measure the S6 arm's stopping behaviour at the cell if the risk assessment needs it.
Awaiting cell access: this could be confirmed or corrected once the physical S6 cell can be observed.
This is advice from this project, based on: safety-535 Verified safety-534 Inferred safety-580 Gap
Why: The table names no model, its figures are identical to the 850 manual's, and it covers only Joints 1 to 3 in one configuration. A separation distance built on it would rest on data that may not describe the S6 arm.
Sources disagree
The xArm manual describes the Control Box emergency stop in ways that do not fit together. Section 2.1.2 says the arm's power supply is removed within 300 ms and that pressing the button powers off the xArm; section 3.2.2 says the button allows the user to cut off the arm's power in the shortest time possible. Section 7.9 says the same button is Stop Category 1, which decelerates the robot 'with drive power on', and section 7.10 gives Stop Category 1 stopping times of 521 to 885 ms. The manual does not explain how power removal within 300 ms fits a powered deceleration lasting up to 885 ms.

Project advice
Deny the S6 agent the SDK calls that change collision sensitivity, collision detection, collision rebound, reduced mode or the safety boundary, or gate them behind human approval.
This is advice from this project, based on: safety-593 Inferred safety-509 Verified safety-558 Verified
Why: UFACTORY says a modified safety configuration makes a new system needing updated risk assessments, and its own SDK notes say not to use set_collision_sensitivity unless required. An agent that can change these settings could invalidate the risk assessment without anyone noticing.
The record says
An autonomous agent driving the S6 xArm 6 through the Python SDK could change collision sensitivity (to 0, which disables collision detection), collision rebound, reduced mode and the safety boundary. Under the xArm manual's own warning, changing the controller safety configuration makes the robot system a new system whose safety reviews, such as risk assessments, must be updated.
Why we infer this: Verified: the SDK exposes these calls and the glossary says sensitivity 0 disables detection; the manual says modifying the controller safety configuration creates a new system needing updated safety reviews. Inferred: an agent with SDK access could make such changes, and the manual's warning would then apply. Whether the Python SDK calls change the same 'configuration file' the manual refers to is not stated in any fetched source.

The S6 xArm 6's controller type (AC or DC), serial number, firmware, Studio and SDK versions are not confirmed. The serial number matters because UFACTORY treats arms before XX1300 differently for friction parameters and the IMU mounting check, and firmware decides which SDK safety calls are available.
Awaiting cell access: this could be confirmed or corrected once the physical S6 cell can be observed.
