Performed build verification tests and system testing of various versions of robots' prototypes on regular basis. Performed system and regression testing of newly added features in the embedded system in C/C++ to ensure that new functions did not adversely affect the robot's essential functions and overall system performance.
• Performed software system and integration tests to uncovered missing, wrongly implemented and under performing features. Performed system testing of the robot's UI layout and related software functions, from the original to the latest designs. Tested UI usability, functionality and performance. Performed system testing of Java based mobile application which controlled the robots' start/stop operations. Utilized minicom and SeggerJ-link debugger to review the tests' console output and exposed potential software problems early. Submitted error reports to the Github Repos and regression tested the revised software once it has been amended.
