Need Help to make a low cost bot

[sdlsahan]

Hello there,

I'm an Engineering undergraduate doing Electrical & Electronic. I'm doing a project related to the 'kilobot' project. I need to create a small robot ( I guess it's called a 'bot') at very low cost. It just needs to have a method for locomotion & a IR module to communicate with each other. Further, it needs to have a microcontroller.

Can I buy it from somewhere like 'ebay'? I need to have atleast 10 of these.

Any help is appreciated. Thanks

There's a ton of them around.

Here's a cheapy from our friends at Servo City:

Arduino's and their clones are cheap, so are IR sensors. Easy to hook up, the IR code is simple.

Buy local at Microcenter ($6 for a UNO R3, last I looked) or buy online For what you are doing a UNO is easy and sufficient.

If you buy on Ebay or some place like Banggood, and I do, be aware of where it is being shipped from. China can take a while.

Thank you very much for your reply.

The size of the robot should be a little more than this. Robotics is not the area of my expertise Is there some place where I could but these small ones?

Since the size needs to be small, I was thinking of maybe using a PIC microcontroller.

Thanks again

Hmmm,

I found the North American distributor

http://www.roadnarrows-store.com/featured-products/kilobot-10-pack.html

But the price is surprisingly expensive

I have seen these before with no intelligence and I had one myself.  Here is a party pack:

Near as I can tell, the PIC still needs a board.
Perhaps this:

That still would need some wiring and perhaps a few extra parts, also needs 5V

More money but 3V.

Which pretty much leaves your question of where to buy a cheap kilobot unanswered, sorry...
