BA SystemesApril 2018 - September 2018

• Created the AlgoGotoXYGamma function through C++  11 and existing AGV track libraries to move the AGV directly to a new point and modify the track without restart. It follows the requirement to fit within its workspace and doesn't intersects with the AGV path. • Used the concept of Docker across all “BA Systèmes” servers to have a universal docker image to access the running of several applications from main master server.
• Setting the CANbus, and programing the communication through C++ on compactRIO to control the AGV setup • Working on attaching Lidar Sensor to the AGV system and retrieving  scandata from it • Using of OpenCV and introducing a factoring in live streaming video through camera to have more stable and clearer image to target objects • Developing algorithm to perform vision processing of the image captured by lidar sensors to create I/0 communication to signal the motion of AGV.
