need help in making manual bot

Hi utkarsh_9,

Read this tutorial - Making your first bOt. Its for robo-newbies so it will surely help you out. 

Regarding rotation of motors in different direction do you want to use wireless remote to accomplish your task? If yes then go through this tutorial once - Building an RF Remote Control. Once you have done that then we can discuss the wire connections required to rotate motors in different diagrams.

hey, thx for those links

i read that and its saying either i shld take d whole mechanism out of a toy car or i shld make 1 for myself. as m just starting nw shld i choose d first optn? wht do u say?

I guess it will be better for you to use the first option . Then you don't really have to do much!

m make complete circuit given to tha tutorial but there is no response frm it what can i do???how can i check that my circuit is right

Hi kapil,

To which tutorial are you referring to? Please start a new forum thread for the same. 

hi....

which is given on this wibsite......

bro plz help me yaar....day after tomorrow there is a robotic compition in our clg ....and my circuit is not working plz help bro......

Tell us your diifcultyin detail

m making all circuit given on this site....only change is m using nxp p89v51rd2 instead of at89s52...but thae probleam is that when m switch off the power supply led of pin no p1_4 is glow and the motor are not ginven any response so i wana now what the process we need to do for check my circuit....??

When you switch off (or rather on my dear?)

Are you using H-bridge, it is necessary for powering the motors

You can make a basic circuit using a motor,h-bridge,uController & led to test all your components

Just write a simple program to light led, and motor on some pins

m not understand what do u wana to say???

Are you using H-bridge to power your motors and which H-bridge?

m using l293d

to test your h-bridge ...

Just write a simple program that will on your motors and light the led

 means discribe me what to do???

frm where i give input .....is this programe......

# include<REG51.h> 

sbit a= P1^0;

sbit b= P0^0;

sbit c= P0^1;

sbit d= P0^2;

sbit e= P0^3;

sbit f= P0^4;

sbit g= P0^5;

void main()

{

a=1;

b=1;

c=1;

d=1;

e=1;

f=1;

g=1;

}

???????????????????

 hey dude i just wanna suggest u to program in assembly language. 

Its comparatively easier to program,understand & implement in microcontrollers.
