Hi there, I am Fares. I noticed your projects and it steered my attention for the fact that I have worked on similar projects before. I have good experience with robot localization using sensor fusion, Kalman&particle filters, visual odometry and SLAM . I also have used PID for multiple purposed like tracking, wall following and obstacle avoidance. That being said, I would like to help you with your task. Feel free to contact me if you are interested.
