Operate the Real Arm · xArm 850 · Step 4 of 9

Run the Arm

Here you use Studio's controls on the real arm: move it joint by joint and in straight lines, guide it by hand, work the gripper, and run, pause and stop an approved program or recording. Keep the speed low, keep clear of the arm, and keep the emergency stop within reach.

UFACTORY Studio's Live Control: the Vacuum Gripper selected with OPEN and CLOSE buttons, Initial Position, Align and a Manual Mode switch, the Speed slider, the Recording panel with Play, Pause, Speed and Times, a slider and plus and minus buttons for each joint J1 to J6, Enable and STOP buttons, the 3D arm and the Real and Sim switch.

Jog the Joints

  • In Live Control, each joint J1 to J6 has a slider and minus and plus buttons. Joint motion turns the joints to reach the target by the fastest path, so the tool's path is not a straight line3.
  • The speed slider sets the speed of Live Control's moves, from 1% to 100%4. It is a jogging speed, not the arm's top speed4.

Jog in Straight Lines

Live Control's linear jog pad: a Base coordinate menu, Z minus and Z plus buttons, a round X and Y pad, RZ minus and RZ plus buttons and a round RX and RY pad.
The linear jog pad: the tool moves in a straight line in the base or the tool coordinate system3. Image: Derek Stringfellow
  • The linear pad moves the tool in a straight line, in the base or the tool coordinate system: X, Y and Z in mm, and roll, pitch and yaw in degrees3.
  • A straight-line move must be solved for the joints, and there may be no solution, several, or only an approximate one5.

Guide the Arm by Hand

Warning

Turn on Manual Mode only when lab staff have confirmed that the mounting and payload settings match the real arm and tool. UFACTORY says it is dangerous otherwise67.

  • With Manual Mode on, you can move the joints freely by hand8.
  • Manual mode turns on only when the arm's and control box's serial numbers are matched9.
  • Teach sensitivity, levels 1 to 5, sets how hard you must push. A higher level needs less force10.
  • Turn Manual Mode off when you have finished moving the arm by hand11.

Use the Vacuum Gripper

  • With the Vacuum Gripper selected, Live Control shows two buttons, OPEN and CLOSE1.
  • Find out which button switches the suction on by test, with lab staff112:
  1. Put a card flat on the work surface, below the suction cup1314.
  2. Jog the arm down slowly until the cup is just on the card. Keep your hands clear of the arm and the card415.
  3. Press one of the two buttons, then jog the arm up a little. If the card lifts, that button grips1.
  4. Jog the arm back down until the card is on the surface, press the other button to release it, and note which button does what14.

Run an Approved Program

Run only an existing program lab staff have approved for the task. Do not create or change one16.

  1. Blockly: open the approved project and click Run to start it17.
  2. Pause: click Pause in Blockly17. How a paused Blockly program resumes is not stated in UFACTORY's manual: ask lab staff before you start18.
  3. Stop: click Studio's STOP. The arm stops at once and its queued commands are cleared. Power stays on19.
  4. Emergency: press the emergency stop on the control box20.
  • Python IDE: Studio's Python IDE is a Python environment that uses UFACTORY's Python SDK directly21. UFACTORY's manual does not describe its run, pause and stop controls, so have lab staff show you them before you run an approved script, and use Studio's STOP to stop the arm1819.
  • Blockly's built-in examples, such as UFACTORY's vacuum gripper pick-and-place, are programs to learn from. Run one on the real arm only if lab staff approve it for the task2216.

Play Back an Approved Recording

  • The Recording panel plays a recorded hand-guided path. Play and Pause start and pause it, Speed sets x1, x2 or x4, and Times sets how often it plays223.
  • Play back only a recording lab staff have approved. Making recordings belongs with programming the arm, the next step162.

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

    The record says

    On 2026-10-22 (Studio 2.6.0, before the update) UFACTORY Studio's Live Control for the xArm 850 had the Vacuum Gripper selected as its end effector, with OPEN and CLOSE buttons; its speed slider was at 12 % and Manual Mode was off.

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

    Reasoning: Verified as a direct reading of UFACTORY Studio connected to the real xArm 850 ('Real' selected) on 2026-10-22, before the firmware update that day (int-608). It is what the screen showed that day and no further: a slider position and a selected preset can be changed at any time. No inspection of the tool is recorded.

    In UFACTORY Studio's Live Control, the Recording panel plays and pauses a recorded trajectory and sets its playback speed and how many times it plays. Creating a new recording turns Manual Mode on so the arm can be dragged by hand, and UFACTORY says to watch the arm's load state while recording, so that a big difference between the actual and the set load does not make the arm move by itself.

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

    Reasoning: Verified for what the dated report from the lab says (S230, S232), as of 2026-10-22, with the photo of the control box. It says where the button is and what is wired; it is not a test that the stop works, which stays unconfirmed until a test is on record. No inspection of the wiring is recorded.

    Currently nothing else is wired into the estop input, and the stations run from a distributed power management system, so not a shared circuit per se, but all pwoer could be cut off if needed
