This paper explores energy harvesting methods, including solar and vibrational energy, for autonomous agricultural robots. It talks about the effectiveness of solar harvesting based on the time of day and the weather. The use of piezoelectric materials and sensors for vibrational energy harvesting is described in depth, with solar energy harvesting. The study emphasizes the significance of task optimization, navigation, energy management, and environmental adaptation. Key factors are durability, upkeep, and remote monitoring. This research advances the creation of autonomous robots that can improve sustainability and agriculture operations by addressing these issues.
