8051 wired robot, for robo race competion....

8051 is used in this project, and 2 motor driver{ LM293D }. 4 motors are connected to lm293d. 2 motors for each for lm293d.
Fordward---P0.0
Reverse----P0.1
left----------P0.2
right--------P0.3
OUTPUT------ i.e lm293d{ 2 ic} are connected to port 1.
When we press forward. Motor 1,2,3,4--revolve clockwise...
when we press reverse. Motor 1,2,3,4---revolve anti clockwise...
when we press left. Motor 3,4---revolve clockwise...
when we press right. Motor 1,2---revolve anti clockwise...
See the image to understand more..though image is not clear...

Any dought of any ideas plz freely reply..

@ yooooo1089
good to initiate

thanks, m working stepper motor 4-wheel robot

stepper is good but robot might be slow coz steppers are a bit slow compared to DC motors. good luck for your 4 wheel drive

Ya, i know, i was building it for robotrack competition where yo need seed very low...

hows the progress? any breakthrough?

well u could have done it without using uc 8051 just by making a small remote (SPDT) switches..

it cud have been cheaper.. nice try though

Actually, THIS is my FIRST project in microcontroll, which i made by myself, so i thought i could upload it.
@Ajay i sorry NO breakthrough? yet! ,but i am working on it,by adding IR controller.

@robotics_mait
Its a big thing for a starter hehe...

@yooooo1089
good job.. well i give you a suggestion.. to keep things simple.. why dont you make it controllable though PC? and more features later on..
