Research on Intelligent Shopping Robot Based on PLC

Abstract

For the large variety of shopping malls, supermarkets, cafeterias and other places, customers need to spend a lot of time looking for goods. Due to this, a smart shopping guide is designed based on PLC. The robot mainly uses the CPU 224 controller to control the motor to drive at a speed of 1 m/s, and the DC brushless motor can load 75 kg of goods at a constant speed. If the distance between the pedestrian and the robot exceeds the allowable range, the CPU will execute the interrupt program and the robot will stop moving to avoid the pedestrian until the pedestrian completely walks out of the maximum allowable range. The sensor could not detect the pedestrian, and the CPU controlled robot continued to work. After testing, this robot can reduce the time spent by customers in finding goods, which greatly saves manpower and material resources.

Analysis of the Resistance of Elderly Individuals Living Alone in Utilizing Self-Checkout Systems in Supermarkets

“…Emerging technologies such as artificial intelligence (AI), cloud computing (CC), the Internet of Things (IoT), augmented reality (AR), big data analytics (BDA), and other digital strategies aimed at enhancing the well-being of consumers and retail enterprises are permeating the retail sector, aligning with the principles of Industry 4.0 and giving rise to Retail 4.0 [2] . Common digital technologies found in brick-and-mortar supermarkets include shopping guide robots (providing product attributes, and functionalities, and facilitating product location and price queries) [3] , self-checkout systems (allowing customers to independently track purchased items and complete self-checkout) [4] , quick response (QR) codes (enabling product production date inquiries, product authenticity verification, and product inspection) [5] , human-computer interaction [6] , handheld self-scanning devices [7] , and AI services [8] . Research around digital technologies in the retail sector is on the rise, which highlights the impact of smart retail on stakeholders [9] .…”
