Review: Android Based Remote Operated Vehicle System

Bluetooth is the buzz word, while designing any automation system for study purpose. Automation of Home/Work place is common using short range communication technology, called Bluetooth. The good automation system allows user to control spy robot or monitoring vehicle as he wishes under his hood. The Bluetooth enabled Android Mobile Phone can be used as remote control device and control the robot/vehicle wireless by standing at safe and comfortable place.

Objective: The system to construct which allows user to control direction of the robotic vehicle standing at safe and comfortable place. The user controlling commands include: Forward, Reverse, Left Turn and Right Turn.

 

 

This Remote Operated Vehicle Control System has two parts: User end where user uses Android App on his Android Mobile to send command to control direction of intended vehicle via Bluetooth means; and Control end where controlling robot/vehicle is connected with main controller unit [which also decodes Bluetooth received commands and act accordingly]. The controller module is based on popular 8051 microcontroller chip. The chips memory resident program/code monitors Bluetooth module over its UART port or serial port for any user commands. If any data found at serial communication (UART protocol) pin, it is decoded as vehicle control command and accordingly executed on output port connected robot driver module. The output port connected Driver Module drives actual vehicle wheels and moves it according to the decoded command instructions.

 

This system allows user to send four vehicle control commands using his Mobile phone App: Move Forward, Move Backward, Turn Left and Turn Right. The Display Module is optional as it helps to see the current status of vehicle at own end.

 

Note that DTMF technique can also be used to control robot at home/work place without touching actual vehicle and its accessories if any fitted like camera.

 

The intended device needs Android App in user Android mobile hand set prior using this system. The range of the system is defined by used Bluetooth's communication range.

 

Since only one robotic vehicle is controlled, less care needed while designing and controlling system.

 

Applications:

 

• The system is used as wireless remote controlled robotic vehicle at home/work-place for monitor or spy purpose.
• Since single point control is possible, useful for non-technical people.
• Since system is embedded type and wireless, portability is done very easily. Changing controlled/operated vehicle is also very easy.
