RoboScan L

Standard Features


  • The robot is located inside the safety enclosure which houses the entire measurement movement system. The safety cabinet has safety light curtains and an emergency stop system. The electric cabinet is integrated to enclosure.


  • ABB Industrial Robot
  • ABB Robot Controller
  • ABB Teach Pendant

Measurement programming software

  • The measurement programming software takes care of running the robot when programs are created. Creating measurement programs is made easy. The measurement programming software is connected with our ViewScan measurement data analyzing program. The measurement programming software depends on the part to be measured. As standard, there are two options:
    • Stresstech Teaching App: suitable for vertically oriented parts like hypoid gears, bearings.
    • HTML-based human-machine interface: Suitable for shafts e.g. for measuring camshafts lobes and crankshaft journals.
  • Three (3) ready made measurement programs are included with the standard system. More programs can be purchased as options.

Part indexing

  • Laser indexing/Infrared camera indexing for sample orientation definition.

Shaft bed

  • The system has a movable sample bed on the guide rail to support the shaft, while preparing for the measurement. The distance between the supports is adjustable. The bed is equipped with easily exchangeable support V-blocks.


  • Touch screen with integrated control panel including following buttons:
    • Emergency Stop push button
    • Start
    • Stop
    • Acknowledge/reset safety
    • System initialization
    • Interrupt measuring
    • Step-by-step mode
    • 3 empty spots for e.g. “Robot home position” option

Horizontal rotation unit with manual chuck

  • RoboScan L is equipped with an ABB MU-200 motor unit, which rotates the sample. The stand is equipped with a 3-jaw chuck with optional exchangeable custom jaws. Chuck can be replaced with drive head.


  • The tailstock clamps the part to be measured between the centers automatically when the safety enclosure doors are closed and a measurement has begun. The whole tailstock is moved automatically on the linear guide for adjusting to samples of different lengths.

Keyboard and monitor mount

  • Ergonomic keyboard and monitor mount which position can be adjusted for each operator.

Sensor and sensor fixture for each sensor:

  • Manual
  • Automated (Automated sensors require storage rack. See Options section for storage racks.)

Barkhausen noise sensors are available in many different types, shapes, and sizes. Sensors are completely customizable to suit any operation. All sensors require sensor fixture, in-built or fixable.

For RoboScan, there are manual and automated sensor fixtures available depending on sensor type and automation level of the system. Sensor fixtures have proximity switches for crash detection. The crash detection switch is activated if the sensor’s inward linear movement is too large. One fixture, depending on the solution, can be equipped up to 2 sensors for multichannel measurements.

Advanced design in sensor fixtures guarantees steady contact between the sensor and the part to be measured. Measurement contact is one of the most critical factors when performing Barkhausen noise measurement.

Standard sensor fixture and sensor models:

OD sensors

  • OD sensor fixture for robot, manual
  • OD sensor fixture for robot, automated
  • S1-15-32-14 Circumferential OD sensor for robot
  • S1-15-32-15 Spring loaded OD radius sensor for robot
  • S1-15-32-16 Fixed OD radius sensor for robot

Each sensor requires its own sensor fixture. Automated sensor fixtures requires sensor storage rack listed in the Options section.

Options for Hardware - Manual Use

Special jaws for chuck

  • Special jaws can be designed for parts that cannot be clamped to standards jaws.

Automated sensor cleaning brush for robot

  • When the sensor is used for measurement, dirt from the sample surface is gathered and the results may become unreliable. The brush removes the dirt from the sensor. It is used when the sensor has traveled the distance defined by the user.

Light curtain safety system for RoboScan

  • The light curtain is equipped with a safety stop function. To be able to run automatic measurement, the light curtain must not be interrupted. Interrupting the light curtain stops all automatic movements. When the light curtain is not activated, only manual operation is possible.

RFID detection for shaft bed V-blocks

  • The V-blocks have RFID detection for the PLC to check that the installed pair of V-blocks is the same as in the measurement program.

Options for Hardware - Inline Use

Pneumatic chuck for robot

  • Pneumatic chuck automatically clamps the part to the rotation unit. Pressure sensors recognize whether the chuck is open or closed.

Automated sensor cleaning brush for robot

  • When the sensor is used for measurement, dirt from the sample surface is gathered and the results may become unreliable. The brush removes the dirt from the sensor. It is used when the sensor has traveled the distance defined by the user.

RFID detection for shaft bed V-blocks

  • The V-blocks have RFID detection for the PLC to check that the installed pair of V-blocks is the same as in the measurement program.

Options for Sensor/Tool Change

Automated sensor/tool change: Sensor storage rack for 3/4 sensors

  • Automated robot sensors are docked to the sensor storage rack in the safety enclosure. The robot automatically picks up the needed sensor from the rack for the measurement.

Pneumatic marker and fixture for robot

  • Pneumatic marker is usually used to mark the first measurement position of the sample before starting the measurement. Marking can be excluded from a measurement program, if necessary.

Options for Software

ViewScan option: Other language module ViewScan option: 2D code reader module and 2D code reader

  • With barcode reader support, it is possible to associate barcodes to measurement templates of different parts. This automates selecting a template and reduces the possibility of choosing a wrong template. Furthermore, it is possible to add more information to measurement comments. Extra information can be coded into the barcode and ViewScan will extract it as defined. The extra information can be handled in several different ways. Barcode support adds the following features to the standard ViewScan:
    • Opening a template that has been associated with a barcode
    • Parsing the barcode and filling in the comment field with values from the barcode
    • Passing the barcode to a TCL script, with which it is possible to fill in more sophisticated values to the comment field.

ViewScan option: Batch support module

  • A batch of measurement templates that are executed automatically one after another can be created with ViewScan. This is useful when using a robot system, when many different surfaces from a part need to be measured. With a batch measurement, the user adds all templates into one batch and executes it. After the first document is measured, the second will be created and measured automatically.

Options for Software - Inline Use

Line integration software

  • The system can be built to support automatic loading and unloading of the part. Includes software functions as well as interfaces for software and safety connections to the loading system. Functions either according to Stresstech specification or customized to customer needs. Software communication to the loading system is via fieldbus, for example EtherCAT or Profinet*. Safety connections are hardwired* and includes safety door/light curtain status and emergency stop button status in both directions. *If other interface is required, please contact Stresstech sales.

Other Options

Documentation in local language Part programming

  • Part programming includes measurement program for one sample and needed ViewScan templates for the programs. One measurement program can include several surfaces to be measured. Rejection limits for the ViewScan software are not included to part programming.
