Project Description: Our innovative smart shop project utilizing voice recognition and EV3-LEGO is a solution the problem. An ultrasonic sensor detects the customer coming, sending a signal to start the program. The people can see everything available in the store on a screen to browse through items quickly. Voice recognition is used to name the required items, which are sent to cart. Finally, after pressing the touch sensor to pay, the conveyor belt will give the items out.
