IOT Based Raspberry Pi Controlled Robot With Video Streamer

摘要

In today’s world, security has become a crucial part of our life. There need a monitoring service to keep track of what is happening in a particular place where security is required. Controlling a robot over the internet can have several utilities, including for security and military use. The purpose of this paper is to control robot from a remote place and stream video back to us. There are two important aspects to work with. One is to take video and watch it live from a remote place and another is to control robot vehicle to move in specified direction. The technology used for this project include Raspberry Pi with internet connectivity, a cloud server, an interface to control the robot and a web camera to take video. The program written in Python programming language is dumped into Raspberry Pi. The purpose of this program is to send video frames taken by Camera to the Cloud Server time to time refreshing every predetermined interval. One can set this interval in the client program itself. Another program called server program running on the cloud server picks up these frames. One can watch this video either typing the server IP address in the url search box in browser or we can make an android app to load this IP address and get live stream. According to the command received the program in the Raspberry Pi control the logic levels at GPIO pins of Raspberry Pi and hence motors connected to those pins will rotate accordingly to go in the intended direction. Through this setup we can monitor anything from time and time and security issue is resolved.
