Thank you so much for the kind words about the videos!
To ensure your tulips are safe, you first need to map the entire perimeter of your lawn as shown in the video. You must guide the robot all the way back to the charging station to successfully complete and save the map; you cannot hit "AUTO" halfway through the initial mapping process.
While the LiDAR should ideally detect the tulips as obstacles and avoid them automatically, if it does not, you should mark those areas as no-go zones within the app. Once the tulips have finished blooming for the season, you can simply remove those no-go zones so the mower can cut those areas again.
