Modelling of tethered UAV system for coconut/ice apple harvesting – A review

A Review has been done in order to develop a prototype of a tethered First-Person View (FPV) drone system for the harvesting of coconuts. The goal of this is to overcome the disadvantages of the human harvesting technique and to boost agriculture in this particular sector. The difficulty of climbing the trees was compounded by factors such as their height and the absence of branches on coconut and palm trees. Coconut and palm trees require an experienced climber who has received the appropriate training in order to scale their trunks. The number of people who actively seek out opportunities to climb coconut and palm trees has decreased as a direct result of the inherent dangers of doing so. People are now hesitant to go back into this kind of profession because the educational background of Indian youth has increased, which has contributed to the death of professional climbers. Additionally, the death of professional climbers is a reason for overcharging by the present professionals from the owner. Even though the technological advancements are better now than the previous times, the majority of the coconut and palm fruit harvesting equipment which is used nowadays are still operated by hand. This results in a sequential increase in the amount of labour required, the cost of operations, and the amount of time required for output. Therefore, tethered unmanned aerial vehicles (UAVs) are the ideal choice for collecting ice apples and coconuts.
