The xArm 850's emergency stop is the red button on its control box, and nothing else is wired into the box's emergency-stop input (as reported from the lab on 2026-10-22). The cell's stations run from a distributed power system that can cut all power, rather than a shared emergency-stop circuit.
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.

Project advice
Before motion is enabled on the xArm 850, lab staff confirm that the arm's speed, payload, workspace and safety configuration are the approved ones, and the operator does not change a protected setting. As read on 2026-10-22 the 850's safety boundary was in effect off, reduced mode was off and no input was set to a safety function, so the operator stays out of the working area while the arm moves.
This is advice from this project, based on: int-603 Verified safety-201 Verified, awaiting cell access safety-203 Verified, awaiting cell access safety-009 Verified safety-144 Recommendation
Why: IntelliMake's rules require the approved speed, payload, workspace and safety configuration to be verified before motion is enabled, and forbid modifying protected settings (int-603). The 850's controller, as read on 2026-10-22, had no effective boundary (safety-201) and no input configured as a protective stop (safety-203); UFACTORY says no people should be in the working area while the arm runs (safety-009), and a safeguard nobody has confirmed is not relied on (safety-144). The confirmation is lab staff's, because the approved configuration is theirs to state.
The record says
The arm is enabled with the Enable button in UFACTORY Studio (it disappears once the arm is enabled) or with motion_enable(true) in the Python SDK.
Enable button on the UFACTOR Studio or Python SDK `motion_enable(true)`.

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.

With 'Clear the IO output when the robot is stopped' off, as it was on the xArm 850 on 2026-10-22, Studio's STOP does not reset the arm's outputs, so an output that switches the suction tool keeps its state after a STOP. Which output the 850's tool uses is not shown.
Awaiting cell access: this could be confirmed or corrected once the physical S2 cell can be observed.
Why we infer this: UFACTORY's Settings page says the option resets the outputs after a STOP command (Verified, the manual), and the 850's screen shows it off for every output (safety-202, Verified). With it off, a STOP leaves the outputs as they were. Inferred because which output drives the tool, and what the tool does when that output stays on, is not recorded (safety-139).
Clear the IO output when the robot is stopped: The robotic arm will be reset to the default status after sending STOP command.
