Railway level gate control

The system allows user to easily open and close the railway gate through the use of a simple android based application. It operates by providing the opening and closing functionality of a railway gate by sending commands through an android application. The remote controlling application is provided through an android application.

Wireless robotic arm

The commands are sent to the receiver to control the movement of the robot either to move forward, backward and left or right using android application device. Four motors are interfaced to the microcontroller where two motors are used for arm and gripper movement of the robot while the other two motors are used for the body movement.

The android application device transmitter acts as a remote control that has the advantage of adequate range, while the receiver end Bluetooth device is fed to the microcontroller to drive DC motors via motor driver IC for necessary work. Remote operation is achieved by any smartphone/tablet etc.

Antenna positioning system

The system uses 8051 family microcontroller and LCD. This LCD is used to display the status of the angle of the antenna. The system makes use of stepper motor to demonstrate as the antenna motor is used to move the antenna in proper direction. Antenna is moved by the user commands received through the android application. These user commands are then received by the Bluetooth receiver modem. As the system receives user commands, it moves the antenna on the basis of input parameters provided.

The input parameters include number of steps i.e. the angle in which the antenna is to be moved. Second parameter specifies whether to move the antenna in clockwise or anticlockwise direction. The third input parameter specifies the speed in which the antenna should move. The speed parameter includes L for low, M for medium and H for high speed.

Hovercraft controlled by android

Here, we have an advanced hovercraft that uses high rpm motors interfaced with an AVR family microcontroller to achieve desired functionality is used. The motor below hovercraft rotates at a very high RPM that allows it to generate a force enough to make it hover on the surface thus reducing the friction below it to minimum. There is a motor propeller mounted behind it to push the hovercraft in forward direction.

A servo motor is attached to the hovercraft rudder that helps the hovercraft to move in desired directions by bending the air at accurate angles. The android application sends movement commands to the hovercraft circuit. The circuit consists of a Bluetooth receiver to receive and process these commands. The commands received by receiver are now processed by the microcontroller and it then operates all three motors accordingly as desired by the user.
