Gripper testing and calibration with GripLAB
Your robot has caused a collision. You have succeeded in aligning the gripper so that the workpiece fits in the gripper without tension, but neither the pick-up position nor the set-down position, nor the machining points or paths in between are OK because the real workpiece no longer matches the tool data. Adjustment of the tool frame in 6D, including orientations, is required to achieve the exact form fit required on all sides of the gripper.
GripLAB provides you with a quick, automatic check and calibration of the tool frame so that your robot is up and running again in no time.
GripLAB benefits
High accuracy calibration system for 6D gripper or tool frame measurement
Complete 6D measurement of a gripper/part in less than 60 seconds
Fully integrated in the cell and under robot programme control
Automatic transfer of the correction values
Allows gripper measurement without the need for probes or other tools
Data communication via Profinet, Profibus, Ethernet or RS232
Fast and efficient recovery of gripper positions on all stations
Calibration accuracy better than 0.2 mm
Complete failure chain from flange to component captured in one step
TCP correction (in 6 dimensions) in the robot controller
High accuracy calibration system for 6D gripper or tool frame measurement
GripLAB - The 6D expert for automated control and rapid calibration of grippers and components
GripLab enables complete 6D measurement of a gripper or component, including orientation, in less than 60 seconds. The system can take control measurements during operation, detect any positional deviation and correct it automatically. Or to get cells up and running again in the shortest possible time after a collision. The system captures the entire possible error chain from the robot flange to the component in one step, thereby increasing the process reliability and availability of handling cells.
- 6D measurement (3D coordinates, 3D rotation angle)
- Calibration accuracy < 0.2 mm
- Data communication via Profinet, Profibus, Ethernet or RS232
Hardware
GripLAB is a compact measuring system with precise laser measurement technology.
It is mounted in the robot cell by means of an adapter plate that is included in the scope of delivery. Connection to the robot controller is via either an RS232 or Ethernet interface. Optional connection via fieldbus, ProfiNET, DeviceNet or EtherCat.
- Mounting in the robot's work area
- Measurement distance: average measurement distance 120 mm (+/- 60 mm measurement range)
- Dimensions: W 85 mm, D 85 mm, H 85 mm

Process
How the GripLAB calibration process works
GripLAB measures a gripped component or the gripper of a handling application in less than a minute. If the control measurement exceeds a specified tolerance, the tool data can be corrected directly in the control. GripLAB can be used during ongoing operation. In this way, creeping deterioration of the gripping process can be detected and corrected at an early stage – before a collision occurs.
The calibration process is demonstrated in the adjacent video.
The individual process steps
Initial situation
The initial commissioning of GripLAB after installation in the robot cell involves a simple motion programme with nine measuring points.
Inspection
After a crash, the test shows that the gripper is misaligned. No additional software installation on the robot controller is required.
Measurement
Automatic measuring of the gripper is done by running the moving programme.
Calibration
Calibration of the gripped part. After automatic transfer of the corrected tool data, the gripping process is precise again.
