Hi, I've read your project concerning thoroughly and it seems that it requires a good knowledge with ROS , Robotics and Raspberry Pi.
I'm a Robotics Engineer with more than 4 years of experience in Robotics Projects including ROS, Raspberry and I believe you can use my experience to achieve your goal.
Also, I have worked on many ROS projects including Localization, Mapping, SLAM, Path planning, Autonomous Navigation, Manipulators, YOLO v3, Voice Recognition projects and some of these projects were implemented with real hardware, you can take a look at some of them in my Portfolio.
Moreover, As a Robotics Engineer, I have also established good experience in many topics in the last four years like Arduino, PCB, Raspberry Pi, C++, Python, Computer Vision, Embedded Systems, Deep Learning, ROS, Sensors, Autonomous Exploration, Localization, Mapping, Jetson boards, Web Scraping.
See you soon in chat!
