hi,
This is venkat, I am son of farmer. In our agricultural fields when we plant paddy i.e rice grains, aT the starting stage we need to be in the fields for more than 20 days throught the day because the flying swans comes into field to eat the dead insects in the field while they roam around and crushe the weak plants and they fail growing. So, to avoid the farmers to be in fields throughtout the day, i am planning to develop a low cost device which makes them not to come into our fields. Hope you will suggest me an idea for this.....
