Operate the Real Arm · xArm 850 · Step 3 of 9
Set Up the Arm
Setting up takes the arm, powered up and connected to Studio, to ready for the approved task: checked against its approved settings with lab staff, enabled, at a known starting position, with the card and the tool ready and the program chosen. Nothing moves until lab staff have confirmed the settings.
Check the Arm's Settings with Lab Staff

Before motion is enabled, lab staff confirm that the arm's speed, payload, workspace and safety configuration are the approved ones23. Read each item to them from Studio:
- State and Mode, in the status panel. On 2026-10-22, with the arm stopped, they read Stop and Position1.
- Mounting: it must match how the arm is really installed. A wrong setting makes the arm misjudge gravity, with false collision stops and uncontrolled motion in manual mode4. On 2026-10-22 it read Floor1.
- Payload and TCP, under Settings > Motion > TCP: they must match the tool actually fitted5. On 2026-10-22 the 850 held the Vacuum Gripper preset: 0.61 kg, and a tool point 126 mm from the flange. These are entered settings, not a measurement of the tool6.
- Safety, under Settings > Safety: the boundary, reduced mode and the speed limits are what lab staff approved. On 2026-10-22 the boundary was set far outside the arm's reach and reduced mode was off7.
- Collision detection, on at the approved sensitivity. On 2026-10-22 it was on at sensitivity 38.
- Safeguards: on 2026-10-22 no controller input was set to a safety function such as Stop Moving9. On 2026-10-23 no guards or interlocks were fitted10. The emergency stop is the red button on the control box, and nothing else is wired into its emergency-stop input11. Stay out of the arm's working area while it moves3.
Warning
Enable the Arm
- When lab staff confirm the settings, click Enable in Studio. It switches on the motors, and the button disappears once the arm is enabled1314.
- From now on treat the arm as moving, even when it looks still: it may be waiting for a signal15.
Go to a Known Starting Position
- Set the Live Control speed slider low before any move. It runs from 1% (2.3 mm/s) to 100% (230 mm/s)16. On 2026-10-22 the 850's slider was at 12 %17.
- Make sure the path is clear, then press and hold Initial Position. The arm moves to its initial position, by default all joints at 018.
Load the Card and Check the Tool
- The workpiece is a business card19. Place it where the approved program picks it up, as lab staff show you, with the arm still2021.
- The 850's tool is a suction tool using a single suction aperture22. Before the run, test it on a card on the work surface with your hands clear: see Run17.
Select the Approved Program
- Choose only the existing program lab staff have approved. Do not edit it: creating or changing programs is the next step, not this one23.
- In Blockly, open that project. Run and Pause start and pause it24.
