Hi All,
I just completed my first robot project. It's based on a dsPIC33FJ32MC202 DSP. I used the Tamiya track kit and dual motor gearbox for the vehicle base. A L298 bridge controller was used to control the motors and a Sharp GP2D12 mounted on a RC servo was used for ranging and navigation.

I'll post video as soon as I make one.

nice creation!
I'm really crazy to make robot. I wanna know your robot circuit diagram , inside what r u using also.
if u don't mind, i wanna make one like yours. Can u email me detail ur all circuit diagram how i make it.
Tks my email is taurus.dj@gmail.com

I thought of..
Starting a blog showing the design of this robot. I've added 2 more IR sensors for wall tracking and improved navigation and adjusted the gearbox so it is now quiet(those tamiya gearboxes are really noisy!)

What did you do to the

Noisy Tamiya!
Yeah, I'd love to know too. I have a Tamiya track and dual gearbox I'm planning to use soon, but the noise!

i'll backup that request.

hi
hi,
nice robot.
how did you make your robot turn. Arent Tamiya track set orange wheels on two sides connected to each other by a long shaft....if wheel on one side turns...it will make the other one on the opposite side turn too.
I am in the process of making my first robot. I have Tamiya Twin Motor Gearbox and Tamina Track set. If I am right.....to turn the robot i will have to just turn only one motor and shut down the other. If this is the mechanism....then how would tamiya track set be used.

The shafts are NOT connected

Hi,
thanks for your quick response.
i still dont get it.
if you look at the photo below, I drew a box to show the long shaft. Even if one wheel is turned by one motor.....this long shaft will make the other side rotate too. wouldnt it?
wouldnt only one wheel turn when only one motor starts. then it would make the wheel of the far right turn too (because of the track)....and then the long shaft would turn....and that shaft would make the wheel on the other side turn too.

Oh the OTHER side?! I
Oh the OTHER side?! I thought you were talking about the gearbox...
Simple, the wheels aren`t stuck to the axle.
Do you have this set actually in your hands now?
