I have been trying to create a machine to climb coconuts as the existing machines are very slow and strenuous to use and frankly, most climbers prefer to climb it manually than use the existing machine, which all more or less use the same concept of the image given below
(Search Google for more).
I have been experimenting with machines and designs like using circular drums and powering them, using raised platforms attached to vehicles but none of them have properly materialized. So now after many futile attempts, I turn to the engineering community to help me and suggest new ideas on their own.
I am new to this and I don't know if I can ask such a question. But still I just wanted to try. Give me any ideas if you can. If you feel that this is not appropriate, please comment below and I will correct it.
