Line Following Robot (AT89C2051)

This Project Line Following Autonomous Robot is based on 8 bit Microcontroller AT89C2051. This Robot follows the black line which is drawn over the white surface or it follows the white line which is drawn over the black surface. The infrared sensors are used to sense the line. When the infrared signal falls on the white surface, it gets reflected and if it falls on the black surface, it is not reflected this principle is used to scan the Lines for the Robot.
All the above systems are controlled by the Microcontroller. In our project we are using the popular 8 bit microcontroller AT89C2051. It is a 20 pin microcontroller.
The Microcontroller AT89C2051 is used to control the motors. It gets the signals from the infrared sensors and it drives the motors according to the sensor inputs. Two stepper motors are used to drive the robot.

can i use 40 pins at89c52 controller by coding with c language

yes you can use it.

sir i have problem with your robat software which program use .a51 with thanks

post you problem/doubt here

J.Binu

How can i increase the speed of this autonomous and how can i controll it better way means on high speed better control???

how can I convert c language to 8051 assembly language?
rply soon.

The speed cannot be increased more because the Line sensing will go fault.
You can use RIDE compiler from www.raisonace.com to convert the C program to HEX code.

the pcb layout (given in the website www.8051projects.info) for the line follower robot given does not correspond to the circuit diagram given.. can somebody comment..

thanks,
Sharma.

Yes, thanks i will correct it soon.
