It's evident that you've put a lot of effort into this project, and your perseverance has paid off! It's impressive how your robot worked successfully and can go in different directions on the racetrack you made with lots of curves. It's clear that you took the time and programmed your robot to navigate various challenges. As you continue to explore robotics, I encourage you to document your process and findings in a project journal or log. This will not only help you reflect on what you've already learned but you can also use it as a resource for future projects. Keep up the amazing work!
