Four Quadrant Operation of DC Motor Remotely Controlled by Android Application

The project is designed to develop a four quadrant speed control system for a DC motor. The motor is operated in four quadrants i.e. clockwise; counter clock-wise, forward brake and reverse brake. It also has a feature of speed control.

The four quadrant operation of the dc motor is best suited for industries where motors are used and as per requirement as they can rotate in clockwise, counter-clockwise and also apply brakes immediately in both the directions.

In case of a specific operation in industrial environment, the motor needs to be stopped immediately. In such scenario, this proposed system is very apt as forward brake and reverse brake are its integral features.

Instantaneous brake in both the directions happens as a result of applying a reverse voltage across the running motor for a brief period and the speed control of the motor can be achieved with the PWM pulses generated by the microcontroller. The microcontroller used in this project is from 8051 family.

Remote operation is achieved by any smart-phone/Tablet etc., with Android OS, upon a GUI (Graphical User Interface) based touch screen operation. Bluetooth device is provided to connect with android application device for the operation of the motor which are interfaced to the microcontroller that provides an input signal to it and in turn controls the speed of the motor through a motor driver IC.

This project can be enhanced by using higher power electronic devices to operate high capacity DC motors. Regenerative braking for optimizing the power consumption can also be incorporated.

Remote Alignment of 3D Dish Positioning by Android Application

The project is designed to develop a dish positioning system which can be operated by using an Android application. The main application of using a dish is to receive signal from satellites and other broadcasting sources. In order to position the dish to the exact angle to receive the maximum signal of a particular frequency, it needs to be adjusted manually.

In order to overcome the difficulty of adjusting manually, this proposed system helps in adjusting the position of the dish through an Android application device. Remote operation is achieved by any smart-phone/Tablet etc., with Android OS, upon a GUI (Graphical User Interface) based touch screen operation.

This system consists of two motors that enable the dish to move both in horizontal and vertical direction. The Android application device acts as a transmitter whose data is received by Bluetooth device which is interfaced to a microcontroller of 8051 family. The Bluetooth device sent data to the microcontroller which is transmitted from Android application device.

The microcontroller sends control signals to the motors through an interface IC also known as motor driver IC. The Bluetooth device serially communicates with the microcontroller.

The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.

Metal Detector Robotic Vehicle Operated by Android Application

The project is designed to develop a robotic vehicle that can sense metals ahead of it on its path similar to sensing land mines. The robot is controlled by a remote android application. Remote operation is achieved by any smart-phone/Tablet etc., with Android OS, upon a GUI (Graphical User Interface) based touch screen operation.

It consists of a metal detector circuit interfaced to the control unit that alarms the user behind it about a suspected land mine ahead. An 8051 series of microcontroller is used for the desired operation.    

At the transmitting end using android application, commands are sent to the receiver to control the movement of the robot either to move forward, backward and left or right etc. At the receiving end two motors are interfaced to the microcontroller where they are used for the movement of the vehicle.

The android application device transmitter acts as a remote control. While the receiver end Bluetooth device is fed to the microcontroller to drive DC motors via motor driver IC for necessary work. A metal detector circuit is mounted on the robot body and its operation is carried out automatically on sensing any metal underneath. As soon as the robot senses this metal it generates an alarm sound. This is to alert the operator of a possible metal (eg: land mine) ahead on its path.

Further the project can be enhanced by mounting a wireless camera on the robot so that the operator can control the movement of the robot remotely by watching it on a screen.

Railway Level Crossing Gate Operation Remotely by Android

The project is designed to achieve control over the railway level crossing gate through Android Application by the station master. Opening and closing of railway level crossing gate involves manpower, which could be often erroneous leading to accidents.

The proposed system rules out the need of any human involvement at the railway level crossing. This system involves opening and closing of the level crossing gate with help of an Android Application Device.

Remote operation is achieved by any smart-phone/Tablet etc., with Android OS, upon a GUI (Graphical User Interface) based touch screen operation. A Bluetooth device is interfaced with the system. When the station master sent command to close from the Android application device (when the train is approaching at the level crossing) to the Bluetooth device which while fed to the microcontroller,  sends an output signal which activates a mechanism to switch on the motor to close the gate.

To open the gate, another command needs to be sent for the microcontroller to open the gate with help of motor driver IC. In this project we use a microcontroller of 8051 family, and the input to it is a Bluetooth device which receives command from the user Android application.

The output to microcontroller is given to a motor through a motor driver IC for required operation. The status, whether the gate is open / close is displayed on an LCD display interfaced to the microcontroller.

Further the project can be enhanced by sending an acknowledgement to the sender about the status of the gate.
