§10 xArm 850

Manuals, Videos and Other Useful Resources

The manuals, software documentation and videos behind this site, with their caption status.

Start Here

This section tells you where to read further, which resource suits which tier, and how usable each one is: whether a document covers this machine or only its family, and whether a video has captions.

  • Start at UFactory Docs, UFACTORY's documentation hub. It links the 850 hardware manual, the Studio manual, the API documents and the release notes in one place12.
  • UFACTORY's set-up tutorials are titled for the xArm rather than the 850, so check each 850 installation step against the 850's own hardware manual34.
  • When checked, none of the videos listed here had captions, so each card says "No captions", and this site states in words every fact it takes from a video567.

Nothing loads from YouTube until you press play on a video. Then YouTube (Google) receives your IP address and this site's address, and its player may store identifiers on your device.

S2 in one line: S2 is the xArm 850 arm that picks up incoming material and moves it between receiving, staging and production89.

Look Back

A question from earlier on, to keep it fresh. Skip it if you like; nothing depends on it.

q-s07-b-02Safety Your hand is on the table edge and the arm is moving toward the table. What is the hazard?
  1. Check option (a)

    Correct. Yes. OSHA lists crushing and trapping between the robot, its tool or the workpiece and other equipment.48

  2. Check option (b)

    Not this one. Shock is a risk from cables and the power supply. A moving arm near a fixed edge is a crush hazard.495048

  3. Check option (c)

    Not this one. Collision detection is not a validated safeguard. The UFACTORY sources do not call it safety-rated, so never rely on it to protect your hand.5139

q-s09-b-02 The 850 carries at most 5 kg. A heavy gripper is fitted to its end. Can it still pick up a 5 kg part?

About:52

  1. Check option (a)

    Correct. Right. The 5 kg covers the tool and the part it holds together, so a heavy gripper leaves less for the part. That the tool counts is this platform's inference from UFACTORY's figure.5253

  2. Check option (b)

    Not this one. This platform infers that the 5 kg covers the tool as well as the part it holds, so a heavy gripper leaves less for the part.5253

Where to Look First

For: Anyone with no robotics background: a visitor, a new operator, a manager
Kind of task: Recognize and recall, with plain-language explanations and pictures

In this part you learn which one place to start from, which two manuals a newcomer needs, and which videos exist, with a warning about the ones made for other arms and about their missing captions. Each resource has a card with its link.

One Place to Start

  • UFactory Docs is UFACTORY's documentation hub. It links the Studio user manual, support articles, the API documents, the accessories manual, the 850 hardware manual and the release notes1.
  • This project's advice: start there, whatever your tier2.

  • Manual or page

    UFactory Docs home page

    UFactory Docs (docs.ufactory.cc) is UFACTORY's documentation hub. It links the UFACTORY Studio user manual, support articles, the API documents (Python SDK, WebSocket API, G-code, Modbus TCP, private TCP, Modbus RTU), the accessories manual, the 850 hardware manual and the release notes.1

The Two Manuals a Newcomer Needs

  • The UFACTORY 850 Hardware Manual covers safety, installation, the electrical interfaces, maintenance and the technical specifications. Anyone can read it; the electrical chapters are aimed at more experienced users10.
  • UFACTORY's Product Downloads page has the same manual as a PDF, version V2.6.1, for reading offline11.
  • The UFACTORY Studio User Manual applies to the 850. It explains the Studio application: live control, Blockly drag-and-drop programming and settings. It suits anyone learning to operate the arm without code12.
  • UFACTORY's Studio page offers Studio for Windows, macOS and Linux, and lists its features, including live control, recording and hand teaching13. The lab uses this desktop app14.

  • Manual or page

    UFACTORY 850 Hardware Manual (online), 1. Safety

    The UFACTORY 850 Hardware Manual (online, docs.850.ufactory.cc), published by UFACTORY, covers safety, hardware installation, controller and robot electrical interfaces, maintenance, production information and technical specifications. Useful for anyone installing or wiring the arm; suits all tiers, with the electrical chapters aimed at intermediate and expert users.10

Videos (No Captions)

  • Live Control tutorial. An official Studio tutorial. It is titled for the xArm, but Studio's Live Control also applies to the 850. It has no captions6.
  • Trajectory recording tutorial. An official Studio tutorial on recording hand-taught paths, titled for the xArm. It has no captions15.
  • Hardware installation. An official set-up video titled for the xArm, while the 850 has its own hardware manual. It has no captions7.
  • This project's advice: use the installation video only as a general guide, and check each 850 step against the 850 hardware manual4.
  • The 850 at work. One video shows the 850 with a dexterous robot hand doing delicate and tool-using tasks16; another shows it in a welding application built by an integrator17. Neither has captions.
  • UFACTORY's YouTube channel carries product demonstrations, application videos and support tutorials. Caption status is given for each video, not for the channel as a whole5.
  • UFACTORY's set-up tutorials are titled for the xArm, so which set-up steps differ for the 850 is not confirmed by video3.

A video listed here is not a recommendation. When checked, none of these videos had captions, uploaded or auto-generated, so a video is only a pointer, and the written manual stays the resource to learn from.

Check Yourself

Answer, then check. Each option has its own feedback, and nothing is scored.

q-s10-b-01 The xArm installation video shows a step, and you want to know whether it is the same on the 850. Where do you check?
  1. Check option (a)

    Correct. Yes. The video is titled for the xArm, so check each 850 step against the 850's own hardware manual.7410

  2. Check option (b)

    Not this one. It is official, but titled for the xArm. Which steps differ for the 850 is not confirmed by any video, so check the 850 manual.34

  3. Check option (c)

    Not this one. The 850 has its own hardware manual, which covers its installation and wiring.107

q-s10-b-02 You need a UFACTORY document but do not know which one. Where do you start?
  1. Check option (a)

    Correct. Right. It links the 850 manual, the Studio manual, the API documents and the release notes in one place.12

  2. Check option (b)

    Not this one. The channel has demonstrations and tutorials, but none of the videos this site links from it has captions, and videos are pointers, not documents. The documents are gathered at UFactory Docs.51

q-s10-b-03 You want to learn to move the arm and build a program without writing code. Which document do you read?
  1. Check option (a)

    Correct. Right. It applies to the 850 and explains live control and Blockly drag-and-drop programming.12

  2. Check option (b)

    Not this one. The Python SDK is for writing control scripts in code, which suits more experienced users.18

  3. Check option (c)

    Not this one. That article gives D-H parameters and link masses for building your own models, an expert task.19

Where to Look When Something Goes Wrong

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 where UFACTORY answers everyday problems, and how to recover a control box you can no longer reach, from written steps rather than from a video alone. It is for someone who will work near or with the cell.

The Help Center

  • The UFACTORY Help Center is UFACTORY's support knowledge base. It has article collections on Studio and Blockly, grippers and IO, the SDKs, ROS and kinematics, hardware, and frequently asked questions20.
  • Its article on collision detection explains how the current-based detection works, and how to avoid false triggers by setting the payload, the mounting direction and the friction parameters correctly21.
  • That is the article to read when the arm stops for collisions that did not happen, for example because the payload was set wrongly2122.
  • Its article comparing the xArm 5, 6 and 7 explains each arm's axis count, payload and motion, which helps place the 850 in UFACTORY's range23.

Recovering a Lost IP Address

  • UFACTORY Technical Support has a video on resetting a control box's IP address. It has no captions, so here are the written steps as well24.
  1. Press the emergency stop button and turn off the control box25.
  2. Connect controller input RI0 to GND with a cable26.
  3. Power on. A beep means the IP address has been reset to 192.168.1.11127.
  4. Remove the RI0-GND cable and wait about 60 seconds for start-up28.
  5. Connect to the arm at 192.168.1.111. The manual's step enters 192.168.1.111:18333 in a browser29; in the lab's desktop app, enter the address in the IP search field and click Connect Server1430.

Check Yourself

Answer, then check. Each option has its own feedback, and nothing is scored.

q-s10-n-01 The arm keeps stopping for collisions that did not happen. Which UFACTORY resource do you read?
  1. Check option (a)

    Correct. Right. It explains how to avoid false triggers by setting the payload, mounting direction and friction parameters correctly.21

  2. Check option (b)

    Not this one. That article compares axis count, payload and motion across UFACTORY's range. It does not cover false collision triggers.2321

q-s10-n-02 Nobody can reach the control box on the network any more: its IP address is lost. Which resource helps?
  1. Check option (a)

    Correct. Right. The video has no captions, so the written steps matter: after the reset the box answers at 192.168.1.111.2427

  2. Check option (b)

    Not this one. The release notes list firmware and Studio changes. Network recovery is shown in the IP-reset video and its written steps.3224

q-s10-n-03Safety You are about to reset the control box's IP address. What do you do before connecting RI0 to GND?
  1. Check option (a)

    Correct. Right. That is the first step of the written procedure, before any wiring is touched.25

  2. Check option (b)

    Not this one. The procedure starts by pressing the emergency stop and turning the box off, then connecting RI0 to GND.2526

Planning Upgrades, Code and Cell Layouts

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 which resources to open before changing the software on an arm, before writing a control script, and before laying out a cell. You also learn to tell a UFACTORY resource from a third-party one, and a released feature from a preview. It is for someone who will set up, program or maintain the arm.

Before an Upgrade: The Release Notes

  • UFACTORY's release notes site lists firmware and Studio releases with their changes, the recommended matching firmware, Studio, SDK and ROS versions, and offline update packages for the 85032.
  • Read it before any upgrade: UFACTORY recommends matching sets of versions, and a combination its table does not list is not one it recommends3233.

What the sources do not settle for this section. Nothing here is papered over with a plausible number.

  • Kind: Gap

    No dedicated official '850 introduction' or 850-specific set-up video was found on UFACTORY's YouTube channel or in YouTube search results. UFACTORY's set-up tutorials are titled for the xArm, so which steps differ for the 850 is not confirmed by video.

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.
