After some weeks of browsing this website, I felt inspired to built something, so, here is the first robot that I'm currently working on.

The idea of this project is to have a platform that can be controlled remotely or work autonomously. For the initial fase, I'm working on some basic remote programmed on Processing, which send commands to the robot via bluetooth (using controlP5 for the UI, and bluetoothDesktop to handle bt communication).

A while ago, I got hold of a car alarm unit and its two remote control fobs. When i hooked it up to 12V I realized that it didn’t  work, not responding to any of the commands from the two fobs even though their batteries were OK. Naturally, I opened up the unit to start harvesting parts and noticed the RF module within (the one that sticks out perpendicularly) and I figured it shouldn’t be too hard to use the module with an Arduino.

In his blog, Michael describes a nice 4WD robot he realized by means of an arduino-compatible board, a motor shield and a couple of XBee radios, which have been used to implement a simple and effective remote control.

Actually, the remote is made up of a standard breadboard equipped with a joystick, a couple of buttons (that can turn the robot in a Kitt-like vehicle!) and the XBee radio. One interesting feature of this project is that the remote controller is fairly simple and has been designed to work with just the XBee radio board, instead of requiring an additional MCU.

More details can be found here.

This is a good example of hacking devices with Arduino. [sspence65] has put on oa good tutorial to start from something easy and simple: IR hack.

Capturing codes from any tv remote, and using them to control devices attached to Arduino Outputs. Press a button on a TV Remote, and the code appears in the serial monitor, Add that code to the case/switch statements in the sketch to control an output pin.

On the [website] there is the full explanation and code to build the same experience, but nothing prevent you to implement a custom way for your IR devices.

[V0R73X], who is 17  has been working on a project, to build A robotic arm. This project started out as a challenge put forward from one of his school teachers to build a robotic arm for $200.  [VoR73X] accepted, and the challenge began.

He came up with a robotic arm that can be controlled from his mobile phone and other bluetooth enabled devices. He also designed it so that he can control it from the infrared remote control of an old tv set. [VoR73X] decided to kept the design simple, to make it easy for others to build.  [VoR73X] has shared the code and a step by step process of how to build in the hopes that others would also like to take up the challenge.  Watch the video after the break for further details on his project.

Having one of those days where your too lazy to do anything? Have a robot doodle for you while you sit back in your favorite chair. This is a very simple drawing robot that was actually started by one of our student engineers. I just made the base plate bigger so I could add a third servo to raise and lower the pen.

My base plate is laser cut acrylic but it could easily have been a small food container, CD or a piece of wood. Just use some double sided tape or hotglue to hold it all together.

This DIYer had a 1st generation iPhone lying around, so he decided to put it to good use.  You can use any phone to accomplish this, even a $10 prepaid phone.  An SMS to the iPhone goes through an Arduino which tells yours car to start or stop from anywhere.  There’s some custom circuitry and programming which is all included in the instructions. When a text message is sent to the iPhone, the iPhone tells the Arduino to start the engine, and the iPhone sends a message back reporting that the start has commenced. Check out the full details to make your own.
