Robot replaces manual testing

Berner & Mattner: MESSINA RS Test Automation for Infotainment/Interior Electronics
Robot-based test automation system MESSINA RS live (Image source:Berner & Mattner Systemtechnik GmbH) (PresseBox) (München, ) Berner & Mattner presents a new solution for the automated test of interior and infotainment electronics and its specific requirements: the robot system MESSINA RS. Practical use has shown that previously extensive manual end-to-end testing can largely be automated in the future. The test system impresses with its flexible possibilities for the verification of various infotainment features for several configurations, reliable test execution and reproducible results. The continuous 24/7 use capability allows to achieve an increased testing depth within a given period of time.

Where once car stereos or climate control were located, now head units of multi-functional infotainment systems can be found. The variety of infotainment functions has to be verified for different implementations. MESSINA RS executes the test sequences through precise control of a six-axis robotic arm enabling to run tests fully automated day and night. This allows for a greater testing depth in shorter time periods. The robotic arm precisely replicates the driver's operation therewith enabling automated testing of new and future operating concepts - such as touch screens, push rotary actuators or the changing of CDs.

Unique architecture and interface

MESSINA RS is based on the proven concept of the testing platform MESSINA. Model-based test specifications are stored in Rhapsody or Enterprise Architect as a sequence. They are imported into MESSINA and automatically converted into the required test codes. The parameters for the test sequence execution can be specified individually. The automatic tool change also allows for different test sequences to run automatically during the night or over the weekend. The MESSINA real-time HiL technology synchronously captures robot actions and all ECU signals relevant for test evaluation. The signals range from voltage and current values to CAN or LIN bus system signals. Open interfaces of the MESSINA RS system facilitate the integration into the customer's existing tool environments.
