Suggestions for a ballfollowing bot
« on: December 12, 2007, 01:11:27 PM »
We are working on a ball following robot and basically it shall have the following components:
1) Image processing part-we have taken care of this with some matlab code.
2) Linking a camera wirelessly to a laptop-not yet figured out
3) Setting up a wired serial link between laptop and bot(read motors)- taken care of using a simple max 232 and at89s52 uC and hbridges(motor           
    control)
4)Setting up a wireless serial link between the laptop and the bot-basically we want the bot to be free of any wires i.e. no wires should go into the laptop from the bot.I figured out  that i can use a virtual serial port of my bluetooth dongle, a Zippys( isscbta) dongle, and use its COM port no instead of COM1(of the serial port keping everything else same) and using a bluetooth receiver(??gess thats what its calld) on the other side and i wont have to understand nethin about bluetooth and have seamless flow of data serially.

I want to kno what this mystery bluetooth receiver should be and what wireless camera should be used?? Moreover any other suggestions are weclome!!

You can just buy a simple bluetooth module like this.
You have to make sure that your microcontroller can be connected to the bluetooth module.
If you're using a popular microcontroller like the Arduino or Basic Stamp, this won't be a problem.

For the image processing part, make sure to check out this site: http://www.roborealm.com/

For extended range, consider XBee instead of bluetooth... just as easy to use, and maybe even a bit less costly.
