Senticart Hardware and Software Functionalities
Hardware
Line Tracking
The cart will arrive at its destination by following the line that has been laid down on the ground because of the application of line tracking in this project. Using the FC 51 IR proximity sensor as a line tracking device. In order to keep the robot from getting off course, two IR sensors were used in this project.
This device uses RFID, also referred to as radio frequency identification, to indicate direction. Card and reader are the 2 components of an RFID system. The cards in this project are laid out on the ground, and the reader is placed into the device of the robot. The robot should pass the RFID card , allowing the readers to detect and execute the indicated direction.
RFID Detection
Software
Dashboard
The dashboard includes monitoring of all carts and their locations and statuses. In the carts section, you will be able to see a card for each cart which displays that cart’s current location and status. In the locations section, you will be able to see which carts recently passed by that location. You can add more carts and locations through the settings.
Logs
In the logs page, you can view either the status logs or the location logs. These logs present a brief summary of what happened at what specific time. You can see which carts went in and out of the station and where they passed by at a given time.
Technical Specifications
RFID
RFID is an identifying technology that use small radio frequency identification devices for identification and tracking. The tag itself, a read/write device, and a host system application for data collection, processing, and transmission comprise an RFID tagging system.
IR Sensor
The concept of working of a line follower robot is based on the phenomenon of light. We know that white colour reflects almost all of the light that falls on it, whereas black colour absorbs most of the light. In case of a line follower robot we use IR transmitters and receivers also called photodiodes. They are used for sending and receiving light.
Ultrasonic Sensor
The duration between emission and reception is used by ultrasonic sensors to calculate the distance to the target. A transmitter and receiver are used in an optical sensor, but an ultrasonic sensor employs a single ultrasonic element for both emission and reception.
ESP 8266
The ESP8266 WiFi Module is a self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor.
