I am currently working on a project where I need to teach my robot to "see" using an ultrasound sensor. In particular it must find and collect drink cans on a playfield and return them to a specific location.
To make the programming easier I wanted to take the sensor output from the robot and display it on the computer as a chart. As I am a terrible programmer I did a quick google search and came up with Gobetwenio.
Hey guys I am trying to read raw data from a gps module using TTL communication on RX pin 0 on the arduino mega. i dont know how to program it since i am total noob at arduino programming.
can someone help me out please.
Alasdair Allan, author of Learning iPhone Programming, Programming iPhone Sensors, and iOS Sensor Apps with Arduino (available along with the Redpark Breakout Pack for Arduino and iOS) sat down with MAKE’s Dale Dougherty to talk about getting iOS devices and Arduino talking to each other.

Dale and Alasdair are just two of your 300 peers you’ll run into at the upcoming Hardware Innovation Workshop, May 15-16, 2012—where MAKE magazine hosts an inspired conversation and curated tour of the unique culture, enabling technologies, and innovations of the maker movement.
The Chaot is my contestant for the LMRv4 Donor Appreciation Robot Challenge.
The machine creates a random number using physical chaos and combines the random numbers to an four digit index.
This index can be used to select a winner.

This device is surely the answer to every DIYer’s prayers. As a do-it-yourselfer, you probably have piles of miscellaneous components and parts left over from various projects. Keeping them organized can be nearly impossible – Until now. StorageBot is a voice-activated system which finds components on demand and delivers them to you:
The StorageBot uses an X and Y storage matrix to easily find parts. When you request a part, the corresponding drawer is pushed open. Stepper motors and gears provide the mechanics while Arduino and Visual Basic power its brain. Check out the complete project instructions to build your own.
I need a camera like a CMUcam or a AVRcam for my robot. I was thinking about getting a CMUcam or AVRcam, but there hasn't been much activity lately by the makers of these cameras, so I'm a little hesitant. I want to be able to do onboard color tracking, blob detection, etc.. And I have an Arduino Mega and Duemilinove to use on my robot. Any help from the LMR society goes a long way, and I appreciate it. Thanks!
Light-based communication seems to wind throughout the MIT Media Lab -- it is a universal language, after all, since many devices output light, be it with a dedicated LED or a standard LCD, and have the capacity to view and interpret it. One such device, coined Droplet, essentially redirects light from one source to another, while also serving as a physical interface for tablet-based tasks. Rob Hemsley, a research assistant at the Media Lab, was on hand to demonstrate two of his projects. Droplet is a compact self-contained module with an integrated RGB LED, a photodiode and a CR1216 lithium coin battery -- which provides roughly one day of power in the gadget's current early prototype status. Today's demo used a computer-connected HDTV and a capacitive-touch-enabled tablet. Using the TV to pull up a custom Google Calendar module, Hemsley held the Droplet up to a defined area on the display, which then output a series of colors, transmitting data to the module. Then, that data was pushed to a tablet after placing the Droplet on the display, pulling up the same calendar appointment and providing a physical interface for adjusting the date and time, which is retained in the cloud and the module itself, which also outputs pulsing light as it counts down to the appointment time.
StackAR, the second project, functions in much the same way, but instead of outputting a countdown indicator, it displays schematics for a LilyPad Arduino when placed on the tablet, identifying connectors based on a pre-selected program. The capacitive display can recognize orientation, letting you drop the controller in any position throughout the surface, then outputting a map to match. Like the Droplet, StackAR can also recognize light input, even letting you program the Arduino directly from the tablet by outputting light, effectively simplifying the interface creation process even further. You can also add software control to the board, which will work in conjunction with the hardware, bringing universal control interfaces to the otherwise space-limited Arduino. Both projects appear to have incredible potential, but they're clearly not ready for production just yet. For now, you can get a better feel for Droplet and StackAR in our hands-on video just past the break.

Ok I am planning on building a "small" humanoid robot that can has computer vision and can do many tasks. I am planning on using a small onboard computer to do all the processing so that it can be autonomous and reduce the need to have another computer on for it to work. Anyway I am looking for a small, not expensive, and easy to use, some what powerfull small computer or single board computer that has usb ports,can run off a small battery and can run lunix. I am thankful for all suggestions.
Everyone's favorite microcontroller has been a boon among hobbyists and advanced amateurs, but it's also found a home among the brilliant projects at MIT's Media Lab, including a groovy instrument called DrumTop. This modern take on the drum pad delivers Arduino-powered interactivity in its simplest form -- hands-on time with ordinary household objects. Simply place a cup, or a plastic ball, even a business card on the DrumTop to make your own original music.
The prototype on display today includes eight pads, which are effectively repurposed speakers that tap objects placed on top, with an FSR sensor recognizing physical pressure and turning it into a synchronized beat. There's also a dial in the center that allows you to speed up or slow down the taps, presenting an adjustable tempo. DrumTop is more education tool than DJ beat machine, serving to teach youngsters about the physical properties of household objects, be it a coffee mug, a CD jewel case or a camera battery. But frankly, it's a lot of fun for folks of every age. There's no word on when you might be able to take one home, so for now you'll need to join us on our MIT visit for a closer look. We make music with all of these objects and more in the video after the break.
