The document describes a proposed multipurpose cart project that follows a user using GPS and Bluetooth. The cart is designed to reduce human effort for shopping and carrying items. It uses an Arduino Mega, GPS module, Bluetooth module, motor driver, magnetometer, geared DC motors. The estimated cost is Rs. 4,100 and would be shared among the six group members. The cart is intended to help elderly and handicapped people shop more easily and can also be used in hospitals, airports, restaurants, stadiums, colleges and offices.

3. • Human following multipurpose cart is an idea to make carts movable without any
interference of human .
• What you need to do is just connect your phone with GPS and the cart will start
following you.
• It is an Arduino based project.
• We will use GPS and bluetooth based systems.
• We can add manual override mode, which will give access to joystick to control the
movement and direction of the cart.
• It is a versatile robot and can be used anywhere according to our own convenience.
• It will be used vastly in shopping malls.

20. • The objective of making this project is to reduce the human effort and make
shopping and carrying stuff easier and less time consuming.
• The main problem faced by elder people is to move the trolley round while
shopping.
• It will also be helpful to the handicapped section of the society.
• Coding for this project is comparatively easy and the control UI for this project
can be easily understood by every user of the shopping cart.

21. • It can be used by elderly and handicapped people for shopping and carrying their
stuff around.
• It can be used in hospitals to carry the medicines and medical equipment’s.
• It can be used in airports and railway stations to carry luggage.
• It can also be used in restaurants for serving food to the diner.
• It can be used in sports stadiums as to carry around water and essential supplies.
• It can be used in colleges and offices as tea trolley or to carry documents and
assignments.

22. • Components were hard to find
• Code was changed as the required magnetometer was not available
• Compass sometimes hangs while testing
• Motor got locked due to clearance of screws
• Time management
