Problem definition
"Design a shoe polishing machine which is affordable and which has reduced material waste and damage along with reduced time of operation and human effort with improved quality of polishing and shinning. The size of the machine should not exceed the dimension 28810 inches, weight of the machine should not exceed 4kg and time required to complete the project should be less than 50 days and the project should not cost more than Rs. 5000.The machine should notify the user after completion of the polishing process and The machine should give a notification when polish box is about to go empty. The machine should start automatically when the shoe is placed on it and it should also display the time remaining for the completion of the polishing process and also the machine should have a power backup to work in times of power shut down."
