Definition 1.2

Design a machine that is automatic and portable it should be equipped with safety features and is reliable,it has storage for the uncrushed and crushed cans but the material of the can should be aluminium or tin and it can crush only 1 can at a time and 10 cans in a minute and should cost **< 5000 ** and machine must be in blue colour

Definition 1.3

Design a machine that is automatic, equipped with safety measures, which is portable and reliable,it has storage for the uncrushed and crushed cans but the material of the can should be aluminium or tin and it can crush only 1 can at a time and 10 cans in a minute and should cost <5000rs and machine must be in blue colour. it has standard parts used in it along with sensing the presence of can,it should also indicate whether the machine is on/off and have storage/cartridge for cans with separate detachable storage bin for crushed cans, and should weigh the weight of the crushed can.
