Award winner from VingPeaw Competition 2543, the robot built with 2051, L293D, and four IR sensors. Simple circuit and platform, quick tracking and easy-understand program using C language.
I designed my robot, which use two motors control rear wheels and the single front wheel is free. It has 4-infrared sensors on the bottom for detect black tracking tape, when the sensors detected black color, output of comparator, LM324 is low logic and the other the output is high. Microcontroller AT89C2051 and H-Bridge driver L293D were used to control direction and speed of motor.

Software
Software for write to AT89C2051 is robot1.hex ,which was written by C-language ,the source code is robot1.c compiled by using MC51 in TINY model with my start up code robot.asm .MPEG files
Sample of competition between 2051 and 68HC11.

The word robotics was derived from the word robot, which was introduced to the public by Czech writer Karel Čapek in his play R.U.R. (Rossum's Universal Robots), which premiered in 1921.
According to the Oxford English Dictionary, the word robotics was first used in print by Isaac Asimov, in his science fiction short story "Liar!", published in May 1941 in Astounding Science Fiction. Asimov was unaware that he was coining the term; since the science and technology of electrical devices is electronics, he assumed robotics already referred to the science and technology of robots. In some of Asimov's other works, he states that the first use of the word robotics was in his short story Runaround (Astounding Science Fiction, March 1942). However, the word robotics appears in "Liar!"

Hi!!!
I want to code of heder file include in cprogram
please reply on
trivedi_rakesh4u@yahoo.co.in
Hi,
Which compiler use in your program and it is possible run on while line and black background.In your program 8051io.h and 8051reg.h added send me this header file in my email address.
please reply……
may i have a pcb and diagram..?
PLESE SEND ME CIRCUIT DIAGRAM OF LINE FOLLOWER ROBOT WHICH IS OPERATED BY COMPARATOR IC(OP-AMP) NOT CONTROLLER IC.
plese send me the circuit diagram and working details of robotic line follower using comparator.
how much volt dc motors does it require…plz reply soon…
Plz send me different techniques of programming Microcontroller AT89C2051
i want programing code for line follower robot.
give me immidiatly,and help for that……..
thankins for
Hi!!!
I want to cprogram codes
please reply on

hi i want to use at89s51 instead of AT89C2051.can i use this Microcontroller for the same circuit.
please provide me assembly language program
on
rameshhardwaria@gmail.com
hay can u pls tell me how can we execute this code in c????
send reply to this :ashok_92008@yahoo.com
please tell me using l293b and ats9s52….
I would like to see a few program for line follower robots micro controller program,,,
hey please can u help me by sending me the source code of this robot i am having my competition please immediatly
the program source code already given on the post, please check…
Please mail me the circuit diagram of the line follower robot
how do i embed pgm into circuit
plz reply me @ yayiharish@yahoo.co.in
pls give me source code of this project on vadiya_keval@yahoo.co.in
hi iam interested in line follower robot and i need the circuit diagram and also the code betails for the microcontroller,Can u send me those urgently
my email tathagata21in@gmail.com
hi
may i know what IC you used in this circuit???
please send the code to my email
carnp.com@gmail.com
thanks alot
i wna trak white light on blue arena can sumbdy tell me whch sensor will be da best
i nees diagram…
plzz help me urgently
hi……i want assembly code for line follower using microcontroller. please send on my email id
please on your circuit is it a dc or stepper motor? if it’s a dc motor can you use a 2 steppers motors instead of DC?
my eamil is betrajack@yahoo.fr a quick answer will be helpfull
help me in making the line following robot
please send pgm for line follower i m looking for .
I want to c cordings for 16f84a line follower robot
iii like thats all robts …….
PLZ mail me circut diagram,assembly program,components required and their specifications on my email address asap.
can i know how u simulated the code first using a suitable software??thanx in advance….
i do not simulated the code… but i do “trial and error” the code on the line track using line follower robot…
plz send me assembly language program for above project
just use SDCC to compile the C language to assembly language or hexadecimal.
Hi Team,
I am looking for below programmer kit.
MICROCONTROLLER ATMEL AT89C2051 COMPILER KIT MC51 in TINY model. (This done by Plermjai inchuay)
Please advice the sources.
Thanks.
James
Dear Sir,
Shall we use stepper motor in Line following Robot?
please send the details of components to my e-mail.
i think stepper motor not good for line follower. ..
please give me the clear specification of which kind of motor you have used in your project
Halo mas.. dari Indo ya? Bisa kasih contoh yang pake ATMega8 nggak? Trims ya.
hey i want a code for line follower robot in microcontroller 8051 language??
will any1 mail it to me….
for 2 motors!!!
Hello!
Where to start the basics of line tracking robots?
Any website any book any thing?
Kindly reply.
hye..
i doing a line follower based on 3 LED.
i don’t know how construct the circuit.
can anyone help me..
Prince_DeviL90@yahoo.com
3 LED is too little for line follower, use at least 5 proximity sensors.
Hi, I am trying to build this but not sure the type of led transmitter and reciever to use. Also the 10v on the l293d confuse me. please help me. Saroeun_1@yahoo.com
thanks
if we use P89V51RD2 microcontroller instead of AT89C2051 then this circuit will work or not??
ple rpy.
it will be work, but you should make some program changes.
plz send me all software programs used in the above projects plzzz,to my mail divyamudragada@gmail.com
Can you send all software program to me? good_2882@yahoo.com.hk
