What is the accuracy of the Wrist camera?
Understand the realistic precision of Robotiq’s Wrist Camera for common applications
Context
In many automation applications, the precision of object detection plays a key role. Whether you're picking parts, positioning them on a fixture, or verifying presence, it’s natural to ask: How accurate is the Wrist Camera?
This article explains what level of accuracy you can expect, and in what context the Wrist Camera delivers its best performance.
Information
Accuracy Specifications by Robot Model
The accuracy of the Wrist Camera depends on the robot model and where the calibration board was placed during the calibration process. The values below reflect typical performance within that calibrated area:
Robot Model | Accuracy |
---|---|
UR3 | ±2 mm |
UR5 / UR16 | ±3 mm |
UR10 | ±3 mm |
These values apply under standard conditions and assume proper calibration. Environmental factors like lighting, part reflectivity, or camera orientation may impact results.
What to Expect in Real Applications
In practice, users often achieve better than ±3 mm accuracy under controlled conditions. However, the Wrist Camera is not designed for tasks requiring sub-millimeter precision such as ±0.1 mm. It's optimized for reliable object recognition and localization, not for inspection-grade measurements.
Ideal Use Cases
The Wrist Camera is a strong fit for:
-
Part presence and localization
-
Regular pick and place
-
Flexible automation with mixed or variable part layouts
If your application tolerates ±2–3 mm variation, the Wrist Camera is a fast and effective option.
If You Need Higher Precision
If your process demands tighter tolerances, consider these alternatives or complements:
-
🔍 Inspection camera systems – designed specifically for metrology or detailed visual analysis
-
🤖 Force Copilot – can improve positioning when paired with a force-sensitive task (e.g. aligning a part using contact)
Choosing the right tool depends on your application’s precision threshold and cycle time constraints.
Conclusion
The Wrist Camera offers solid accuracy for standard pick-and-place and detection tasks, typically within ±2–3 mm depending on the robot model. While it’s not intended for inspection-level precision, it remains a powerful tool for flexible automation.
