Hi All, Please find the minutes of the meetup @BOT VFx on 27th October 2018.
Talk 1: Computer vision in Test automation using Robot Framework. Speaker: Vijayakumar Vijayakumar gave an introduction to Testing and various types of testing like Unit Testing, Integration Testing. For this talk he demonstrated the Integration testing of "Orpat digital Alarm Clock" using computer vision and Robot framework. Input Automation: He automated input buttons(hour, minute, set, power off) of the clock with relay control that he integrated with his laptop using serial port. Using the python 'serial' port app running on his laptop he controlled the relays and hence inputs to Orpat clock. He wrote a python library that abstracts the device. Capturing LCD output: He setup the Document Camera that records the LCD output of the Orpat clock. This camera is connected to the same Laptop where input is controlled. From Camera video is read using ffmpeg app at 1 fps. These video frames are given to SSOCR library to read and understand the display in the Orpat clock. Using the input, output automation and library abstraction. Vijay showed command line invocation showing each test execution. Then slowly he built the Robot based test suite that checks various conditions. Live Hardware Demo made it an awesome experience. Talk 2: Scientific computing using python Speaker: Ashok Govindarajan. Simulation of wireless channel attenuation/disturbances in python using scipy/numpy. He explained the importance of simulation. He explained various concepts like probability distribution functions especially poisson distribution's role in finding the amount of time one need to wait in a queue. He finally concluded Scientific computing === Statistics + Probability. He demoed his program to audience. He introduced numpy, scipy and matplotlib. Thanks With regards Kamesh Jayachandran
