Hello Guys my Self Mohanish From India and i'm also an Mechanical Engineer and working as a Designer. i would like to know that how to make robots? frankly speak i'm totally unaware about it. i was try searching on Google but cant find anything what i required. on Google i was find this site and its look like what i required
I need to know how robot works?
I need to know which parts are Required for making 4 wheel Drive Robot with operated with Laptop or remote control
I need to know what parts do what things.
i need to know from where i get that all parts.
i need to know how to assembled all that parts electrically and mechanically both
All of u r requested to shear your knowledge with me
here i'm attach 2 Photos which i was make in 3D

When looking at the EZ-Robot office webcams I found that Team DJ is working on a project that I was thinking of doing...
Okay, so I ask the question. Can one run a stepper motor with less than 4 digital ports from the EZ-B4? And in addition how to control speed?
It can be easily done. There was a couple threads on this forum describing how to use stepper motors with ezb. Do a search using stepper motor and dig through the results. I'd love to do it for you but I just don't have the time.
I have read everything and I understand how to run a stepper with the EZ-B but my question is can it be done with less than 4 digital ports? Can it be done with a Sabertooth? Or is there another driver out there that could run a stepper with just one input?
Have you searched the internet for break out boards that will help EZB drive your stepper. I don't think a Sabertooth will do it. It took me about 30 seconds to find this at SparkFun that may work for you:
EasyDriver Stepper Motor Driver
They claim it is compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). EZB certainly can do that. It also looks like it will only require one port off an Arduino. If Arduino can do it then EZB can.
I'm sure there are other driver boards out there but this one may be worth a try. Check out the user feedback on the page I pointed to and have fun!
EDIT: Here's more from Pololu. Nice choices depending on how much current your motor will be pulling: Pololu Drivers

is this ok? or i miss some thing? if it is please let me know
@mohanish... Replace #01 with an EZB4 board instead of Arduino and your perfect....
Thanks A Ton! @Richard R
Didn't you say in the beginning of the thread that you wanted to add vision to a robot using the camera.
