INTRODUCTION
• Aim of the project is to use a mobile phone to
control a robotic arm mounted on a Robot.
• Provides robust control, large working range.
• Control of robot involves 3 different phases:
a) Processing
b) Action
c) Detection
DTMF
Frequencies 1209Hz 1336Hz 1477Hz
697Hz 1 2 3
770Hz 4 5 6
852Hz 7 8 9
941Hz * 0 #
DTMF FREQUENCY KEYPAD
DTMF decoder is connected to mobile phone via Head-Phone port.
It generates two frequencies respective to key pressed from mobile.
MICROCONTROLLER
• Advanced-RISC architecture.
• 16K bytes of In-System Programmable Flash
Program memory.
• Internal and external interrupts.
• 32 general-purpose registers.
• High-performance, Low-power AVR 8-bit
Microcontroller.
DC MOTOR CONTROLLER
L293D
• Microcontroller output is not sufficient to driveDC motors, so L293D is used.
• L293D comes in 16-pin DIP. It can providecurrent upto 600mA at voltages from 4.5V to36V.
• It can be used to drive inductive loads such asrelays, solenoids etc
• In the project it is used for simultaneous bi-directional control of two DC motors.
SOFTWARE USED
1. KIEL MICROVISION (EMULATOR)
A HEX file can be created with the help of Keil which is required for burning onto chip. It has a powerful debugging tool which detects most of the errors in the program.
2. 8051 LOADER
8051 loader is a software developed by robosapiens. The HEX file created with the help of keil was selected through it for programming the microcontroller.
ADVANTAGES
• Wireless control
• Usage of remotely controlled military vehicles inthe Winter War .
• Takes in use of the mobile technology which isalmost available everywhere.
• This wireless device has no bound on range andcan be controlled as far as network of cell phone.
