Bluetooth and XBEE

Hi, I am working on a project that includes contolling a robot wirelessly though visual basic 2010. And I was researching and found that if you use an xbee it is the same code as when using a usb cord. But i want to use bluetooth instead. And I was wondering if the code is the same when using bluetooth (like the xbee). I assume that it is the same because it is a form of RF. But I need to know from LMR if it is the same code with Bluetooth or is it different.


Bluetooth AT commands

Hi I bought bluetooth module from ebay. I connected to the atmega and comunicate with my laptop. It works great. I set (in atmega) communication 9600 Bd, but hyperTerminal (auto-detect) shows 2400 Bd. I tried lots of tutorial how to change baud rate (or name, key, ...) using AT commands, but Hyperterminal does not work and the other also. They connected to bluetooth, but when I try wrote something it does not shows in terminal (keboard do not work :D in terminals ). Any idea how comunicate with bluetooth using AT commands? Sorry for my English :) .

Arduino Blutooth

Hi I have an android phone and i want to be able to send my text messages, emails, and other stuff to my arduino by using bluetooth. Is that possible? How would you get the phone to send that?

Need Guru Help Regarding Micro-Controller + Wireless

Hello !
What is the most inexpensive, yet stable robust and relatively fast micro-controller + wireless setup?

I have been asking this question to myself for way too long... Now, I'm curious of your experiences in the different flavors available..

In my specific situation talking back and forth to a computer or laptop would be the primary objective.

Bluetooth control from your Android phone or tablet

Hello, I am the author of Mintoris Basic for Android phones and tablets.  I recently added Bluetooth serial communications to the language with the intention of making it very easy to communicate and control robots.

Here is a short example program in Mintoris Basic which connects to a device then transmits data from the phones accelerometer.  So as you tilt the phone or tablet in any direction, the amount of tilt is sent to the Bluetooth device.

dim a$(0)
dim c(4)

Bluetooth module worth keeping?


Well here is the problem, I have a Bluetooth module and I did use it on a previous bot, but it had a library specifically for that module so I was only copying a pasting code to get it working.

Which bluetooth?

So I am planning on going wireless with my robots and I was wondering which one I should buy. I was looking at sparkfun and I found many blutooth. What qualities should I look for are some better than others? Also I intend to use the bluetooth for only about 100-150 ft and I am mostly going to use it for the arduino. This is what I found so far:

Processing talking Bluetooth

Getting Arduino talking through Bluetooth seems like an easy task. There are plenty of tutorials showing you how to do the initial setups and most Bluetooth modules have their own wiki pages + datasheets you can use. It works, you can make the connection, use a terminal software, send packets back and forth. It's all good. Or is it ?


Computer On Wheels Controller

Hi guys,
Since last week, I've been learning c++ and openFrameworks and creating a application to control any robot with a computer on it or, at least connected to one by someway.
It is supposed to be simple to implement and use.
You just need to run the application and program your robot to read the following chars and act corresponding to them:
  • 'w' to move forward;
  • 's' to mo

MY AGV development platform


I decided to do this as a blog as I plan for this to be a long term test platform as I mess around with different tech along the way.

OK I started by buying this RC truck chassis on eBay:

It uses a 7.2v NiMH battery and powers the motor using an ESC that delivers a few AMPs of 6v through a BEC to power a transceiver and the steering servo. Instead of a transceiver, I am hooking up an Arduino Fio and various components, housing them in a project box:

Bluetooth and Arduino

Happy Holidays LMR,

Calculon is wondering if any of you have used bluetooth with arduino successfully. And if so, what did you use?

He's aware that there's an Arduino BT board, but he's looking to use a standalone module with his Mega to talk to his android phone. Anyone have any experience with this?

Would this work for this purpose?

Servo'd Bluetooth'd Tamiya Bulldozer Robot


Hey cats. I spent the past 2 days writing a new design/control app for the ez-b and decided to make a new robot as a test platform. so yesterday i noticed i had a few of these bulldozer kits lying around, but i find them annoying due to the DC motor gearbox. A few years ago i started using modified servos instead of dc motors on the bulldozer kit. I get the odd email asking how i did that...

Soooooooooooo, i coupled the two together. A video showing how to build a servo driven tamiya bulldozer and the ez-builder

Hello! I'm new here


Hi there. I have seen a few videos from this website. I've even been told a few time to sign up, so here I am! :) Glad to meet you all! Lots of fun projects on here. I've been looking through the Robots and Blog area, some real neat stuff.

I'm a robot builder also, sorta, kinda. I spit out new ones often, so I may not have time to post them in the Robots section. But I really like the active forum here! I'll probably be around often. 

Here's a few links to some of my robots if you're interested:
