✓ xArm 850

Beginner Checkpoint

You have walked the core of the beginner path. These five questions check the things a new operator must know: what the arm does, where it sits, what goes in, what comes out, and what can hurt you. Nothing is scored. Then try telling it in your own words.

What you write stays in this box. It is never saved or sent.

Tick the points your answer included.

q-chk-01 In one line, what does the xArm 850 at S2 do?
  1. Check option (a)

    Correct. Right. That is S2's job in IntelliMake's Phase 1 cell.1

  2. Check option (b)

    Not this one. Engraving is the laser engraver's job, at S5, not the arm's.6

  3. Check option (c)

    Not this one. That is the downstream arm's job: S6, an xArm 6, after processing.7

  4. Check option (d)

    Not this one. Monitoring the factory is done by Camera C1, Camera C2 and the S11 monitoring system. The arm has a camera of its own, on the arm itself, but it is not one of those: the arm is to use it for its work, to select the correct material for an order, and possibly to check it.89101112

q-chk-02 Where is S2 in the gift flow?
  1. Check option (a)

    Correct. Right. S2 is the first Cobot Handling step; S6 is the second.132

  2. Check option (b)

    Not this one. That later Cobot Handling step belongs to S6, the downstream arm.2

  3. Check option (c)

    Not this one. Packing & Labeling is the last step of the flow; S2 works near the start.132

q-chk-03 What does S2 take in?
  1. Check option (a)

    Correct. Right. The material comes from S1, and in this project's design S2 also waits for S4's ready signal.14115

  2. Check option (b)

    Not this one. Engraved parts are what S6 handles, after the laser, not S2.7

  3. Check option (c)

    Not this one. The order starts the flow, but S2 handles material. In this project's design, the data it takes in includes S4's ready signal.13115

q-chk-04 What does S2 hand on?
  1. Check option (a)

    Correct. Right. S2's route for a part is S1 to S3, then S3 to S4; in this project's design, S2 also reports its own state.1617

  2. Check option (b)

    Not this one. S2 comes before the laser, and engraving happens at S5.136

  3. Check option (c)

    Not this one. Routing parts after processing is S6's work, after the laser.7

q-chk-05Safety Which of these can hurt you around S2? Choose all that apply.
  1. Check option (a)

    This one applies. Yes. Being struck or caught is the main hazard of a moving arm.18

  2. Check option (b)

    This one applies. Yes. Items can drop on power loss or from an unstable grip.19

  3. Check option (c)

    This one applies. Yes. A still arm may be waiting for a signal and about to move.4

  4. Check option (d)

    This one applies. Yes. The arm and control box get hot in operation.20

  5. Check option (e)

    This one does not apply. Keep out while it runs. Collaborative is a label, and UFACTORY's own manual keeps people out of the working area.321

  6. Check option (f)

    This one does not apply. Do not count on S11 or the cameras to protect you. Stay out of the working area while the arm runs.223

Each number in the text points here. Every entry states its confidence class in words and keeps its evidence one click away. How to read the labels.

Key to the badges
Confidence: Verified
A manufacturer or IntelliMake document says so, the project owner stated it as the design, or it was observed directly. It does not mean anyone measured it at S2.
Confidence: Inferred
Reasoned from Verified facts. The reasoning is printed with the record.
Confidence: Assumed
Plausible but untested. The record says how it would be checked.
Kind: Gap
Not known. No figure or answer is given in its place.
Kind: Contradiction
Sources disagree. Both sides are shown, and the site does not pick one silently.
Kind: Recommendation
Project advice drawn from the records it cites. Not a fact about the machine and not a confidence class, so the filter never hides it.
Awaiting cell access
Awaiting cell access: could be confirmed or corrected once the physical S2 cell can be observed.
This project's simulation and agent design, not the physical cell
This project's simulation and agent design, not the physical cell.

  11. Confidence: VerifiedAwaiting cell accessint-114

    The record says

    The xArm 850 at S2 has a working camera of its own (confirmed after the station was set up on 2026-10-08), on the arm itself. It is not one of the cell's numbered cameras: the arm's camera and those cameras are not related.

    Awaiting cell access: this could be confirmed or corrected once the physical S2 cell can be observed.

    Reasoning: Verified as a statement of the lab's state on the dates given: that the camera works, S172 (2026-10-09), after the station was set up on 2026-10-08; that it is on the arm itself and is not one of the Cx cameras, S181 (2026-10-12) and S183 (2026-10-13). No inspection is recorded here. S182's 'No cameras have been set up yet' (2026-10-12) was given to a question about 'Cx' and does not name this camera; whether it reaches this camera is a reading this record takes no position on (int-116).

  22. Kind: RecommendationThis project's simulation and agent design, not the physical cellint-053

    Project advice

    Until S11's safety function is documented and verified, neither learners nor the S2 agent should treat S11 or the cameras as a safeguard. The S2 agent must not rely on them to stop motion or to protect people.

    This is advice from this project, based on: int-024 Verified int-050 Gap, awaiting cell access

    Why: S11 is described only as monitoring that includes safety (int-024). Nothing establishes a safety rating, stop authority or response time (int-050). Treating an unrated monitoring system as a safeguard is the failure the Q3 disposition warns against: an Assumed safeguard mistaken for a confirmed one.
