Implementation of A Line Following Cart Based on Ultrasonic Sensor

Nowadays, industries, hospitals, supermarkets are developed with technological advancements. Materials movement in industries, transportation of medicines to rooms, emergency wards and operation theaters in hospitals and people put the items purchased in supermarkets in a trolley or cart because it is the easiest method used in supermarkets, hospitals and industries to carry objects. However, throughout the whole process of carrying goods from one place to another takes more time and physical energy. Nowadays industries, hospitals and supermarkets are very busy with the heavy load of work and this cart can also be used without touching it which is much more important during covid time.Implementation of new idea and latest technology are the major gift to the recent generation. Utilization of these technologies has shrunk the world and brought very easy within our reach. The expansion and growth are the ideas and concepts are directly linked to the economic growth as well as development of the country. This paper presents Arduino based line following cart. Successful implementation on control is depend upon the logic utilization and with proper knowledge on the specific design model. Basically a line following cart can easily follow the line as per instructions loaded in the controller.
