In this research, scientists developed a robot for harvesting lettuce and detecting plant diseases in vertical farming greenhouses. The goal was to make harvesting more efficient and ensure high-quality produce. The robot uses a special navigation system and harvesting mechanism to work inside the greenhouses. By using this system, farmers can save time and effort while maintaining supermarket standard lettuce quality. The robot can also help in quickly identifying plant diseases, which is beneficial for overall crop health. This innovation shows promise for improving the efficiency of vertical farming and the quality of harvested crops.
