The implementation of a service robot for shopping-market assistant is presented. The scaled prototype robot is a four-wheeled differential vehicle based on microcontrollers and ultrasonic sensors for following a person to a certain distance while groceries are selected. Each grocery is identified by a unique number through radio frequency tags. The grocery is placed in the basket of the robot by the user, this identifier is read and transmitted to a remote computer by means of ZigBee wireless communication protocol, querying to a database for information about the grocery, which is presented to the user on a color display with the bill. The results in convenience stores have been shown that the autonomous robot is a reliable tool for shopping assistant.
