Bluetooth controlled Robot using Android Smart Phone

Abstract

Robot is a reprogrammable, multifunctional device which is primarily designed to do work like human such as pick and place, loading and unloading, surveillance, health care, industrial, aerospace application. Robots can perform dangerous and accurate work to increase the productivity as they can work 24 hours without rest. This system deals with the design and control of automated robot which can move in desired direction using android application. An android application has developed using Bluetooth App and a Bluetooth communication is made with robot which interfaces with microcontroller to change direction. So the Android phone will transmit command using its in-built Bluetooth to the robot so that it can move in the required direction like moving forward, reverse, turning left, turning right and stop. Two obstacle detecting sensors are attached on the left and right side of the robot. If there is an obstacle in the moving direction, it will automatically change its direction.

Existing System

The existing self-propelled monitoring and surveillance Vehicle can be divided into the following parts: Wireless IPCAM video capture system, face detection system, remote monitor and alarm transmitter system, RFID position detection systems, and cell phone monitoring and control system. The diagram of system architecture The self-propelled vehicle uses RFID technology to control the moving direction. RFID tag is installed in the right hand side of the self-propelled vehicle. When the self-propelled vehicle moves to a predefined routing path installed with RFID reader, the RFID reader would detect the RFID tag and send the signals back to the server to show the detected position on the map to indicate the status of the automatic vehicle.

Proposed System

The architecture is used for educational robotics, because students can build their own robots with less cost. Smart Phone controlled robot is controlled by using Android App instead of any other method like buttons, gesture etc. Here only needs to touch button in android phone to control the robot in forward, backward, left and right directions. So here android phone is used as transmitting device and Bluetooth module placed in car is used as receiver. Android phone will transmit command using its in-built Bluetooth to robot so that it can move in the required direction like moving forward, reverse, turning left, turning right and stop.
