Information About the project And the purpose of this project is to automate the fruit transport system in this factory In this industrial plant good carriers are essential to carry goods from one place to another place. In most instances, carts or trucks were used with human labour. This manual process is unreliable and unefficient which causes wastage of time and money DSE 18.2 NATIONAL INSTITUTE OF BUSSINESS MANAGEMENT KURUNEGALA 3/1/2020 3
