Troubleshooting Robotiq Wrist Camera Installation Guide

After correction, the robot controller should load the Robotiq camera integration, report an available vision service, and communicate with the Wrist Camera without requesting a missing URCap USB. Treat camera hardware, the installed URCap, the Vision Server, and camera firmware as separate diagnostic layers.

Fault boundary and terminology

The term URCap here means the software extension installed on the UR robot controller. The USB device used to transfer or install that extension is installation media; it is not the camera itself. A message interpreted as “no URCap USB” therefore does not, by itself, prove that the Wrist Camera has failed.

The integration has four functional states: the camera must have a sound physical connection, the controller must retain the URCap package, the URCap must load its vision service, and the running software must communicate with the camera firmware. The displayed actions—Uninstall Vision Server, Refresh vision status, and Update camera firmware—indicate that troubleshooting has reached the software or service layer, but they do not identify which layer caused the fault.

Check 1: Camera installation and physical connection

1. Stop camera-dependent operation and place the robot in a state where inspection will not initiate motion.
2. Compare the installed camera, mounting arrangement, connector seating, and cable routing with the Robotiq instruction manual. Expect the camera to be mechanically secure and every required connector to be fully seated.
3. Inspect the full cable path for looseness, pin damage, crushing, tight bends, or strain at the wrist. Expect no visible damage and no connector movement when the cable is handled gently.
4. Disconnect and reconnect only with the equipment in the state required by the instruction manual. Expect the connection to latch or seat normally.
5. Return to the camera interface and use Refresh vision status. If status becomes available, proceed to Check 5 verification. If it remains unavailable, proceed to Check 2.

A month without camera use is not a diagnostic cause by itself. Reconnection can expose a loose connector, changed controller state, missing installation media, or a software component that is no longer running. Use the post-reconnection reading to select the branch.

Check 2: URCap package and USB recognition

1. Determine whether the controller is reporting that USB media is absent or that the URCap is absent. Expect these to appear as distinct conditions in the controller’s installation or extension view.
2. If USB media is required for installation, insert the media and check whether the controller can browse it. Expect the media and the intended Robotiq installation package to be visible. If the media is not visible, test the media independently or use known-readable installation media prepared from the approved package.
3. Open the controller’s installed-extension list. Expect one Robotiq camera URCap entry, not merely a package visible on USB.
4. If the entry is present, do not reinstall it yet; continue to Check 3. If it is absent, install the approved package according to the instruction manual, complete any controller restart requested by the installation workflow, and then continue to Check 3.

Repeated removal and reinstallation is poor diagnostic practice when the controller already lists the extension. It changes the software state without proving whether the original fault was USB recognition, extension loading, vision-service startup, or camera communication.

Check 3: URCap loading state

1. After any required restart, reopen the installed-extension view. Expect the Robotiq camera URCap to remain listed and to show no installation or load error.
2. Open the camera interface. Expect the normal camera controls or status page rather than an installation prompt.
3. If the controller again asks for a URCap USB, return to Check 2 and verify that the correct package was installed rather than only opened from removable media.
4. If the interface exposes Refresh vision status, select it once and wait for the interface to finish updating. Expect a stable service state. If the service is unavailable or the interface offers Uninstall Vision Server, proceed to Check 4.

The installed URCap and the Vision Server are different components. The URCap supplies the controller interface and integration logic; the Vision Server supplies the service used by that integration. A visible URCap does not prove that its service started successfully.

Check 4: Vision Server and firmware branch

Use Uninstall Vision Server only as part of a controlled service-reinstallation path. Removing a service that is already running can replace one communication fault with a missing-service fault. Likewise, do not start a firmware update merely because the option is displayed; first establish that the URCap is loaded, the Vision Server is available, and the physical connection is sound.

Resolving procedure

1. Correct any loose or damaged camera connection found in Check 1.
2. Restore readable USB installation media only when the controller actually requires the package.
3. Install the Robotiq camera URCap if it is absent. If it is already present and loads normally, retain it.
4. Run Refresh vision status. Repair or reinstall the Vision Server only when its status remains unavailable.
5. Run Update camera firmware only when the installed interface requests it and the camera connection is stable.
6. After each state-changing action, complete the restart requested by the controller workflow before judging the result.

Change one layer at a time. Record the screen before and after each change so that a recurring failure can be assigned to media recognition, URCap loading, service startup, or camera communication.

Numbered verification checks

1. Check 1: Open the installed-extension list. Expect the Robotiq camera URCap to remain present after a controller restart.
2. Check 2: Open the camera interface. Expect no request for missing URCap USB media.
3. Check 3: Select Refresh vision status. Expect the status to settle in an available or ready state rather than remain unavailable.
4. Check 4: Reconnect through the normal operating workflow. Expect the camera interface to detect the Wrist Camera without presenting service-removal or firmware-recovery actions.
5. Check 5: Run the manufacturer’s installation test with the camera mounted as specified. Expect the test to complete without losing camera communication.
