Automation and Control

 

 SHOPBOT

SHOPBOT is a robot that can be used in automation of shops. It receives orders from registered customers as SMS in prescribed format and sends the customer a reply after checking for product availability and then processes the order. It is capable of moving to the required stack (using image processing), scanning the product codes (barcode scanning), and picking the correct item (Suction mechanism). Reception and interpretation of customer SMS is realized using a GSM modem, and the entire system is integrated with an Arduino Mega development board.

This robot uses features like GSM communication, Image processing, Barcode scanning etc. It uses suction cups driven by vacuum generators to grab the item. The robot is a model depicting a possible shop automation system. View More

HOME AUTOMATION USING WI-FI

This project uses 802.11b/g WLAN connectivity based on Texas Instruments CC3000 WiFi module. Power measurement is based on Allegro Microsystem’s ACS712 based current sensor. Both the modules are integrated and controlled by TI’s Tiva C Series Launchpad.
An HTML based webserver is made in the microcontroller, which could be accessed by any web browser over the same WiFi connection or through the internet, provided port forwarding is activated in the router. The CC3000 module communicates to the Launchpad via SPI protocol, and has built-in TCP/IP stack. Phase control of AC is achieved using BT136 triac and MOC3021 opto coupler. By proper phase control the effective power can be controlled and hence the brightness of a bulb or speed of a fan could be controlled. The current sensor outputs a periodically varying voltage that is linearly proportional to the current value, by calculating the r.m.s value the average power of the device is calculated.
