Chris from PyroElectro has written a multi-part tutorial on building motor control firmware for a microcontroller, a PIC 18F252. This tutorial is based on his earlier robot chassis, but the principles relating to the use of a motor controller IC … Read more
Hazim Bitar writes in about the GOduino II motor driver project. In addition to the Atmega328p w/Opti bootloader, he uses a L293D h-bridge and various supporting caps and resistors giving the project a total estimated cost of about $20. Visit … Read more
The 2012 Atmel Robotics Contest (ARC) is currently underway. The contest is open to university students 18 years or older in North America, South America and Europe, and the goal is to develop a battery-powered 3D version of the Atmel … Read more
The developers over at Piccolo are working on a CNC-bot designed to draw small pictures, and which could be reprogrammed for other purposes. According to the developers, “We are currently refining the Piccolo prototype into an open-source design that is … Read more
Autonomous flying robots. They can navigate obstacles, map insides of buildings, fly in formations, build structures, and more… Just add lasers. Via Hacked Gadgets.
Kristian Lauszus updates us on this remote controllable balancing robot project. In development of this project, Kristian created the PS3 Bluetooth Library both for Arduino and the FEZ Devices. However, not content with the performance of the FEZ, an mbed … Read more
Oscar has written an article describing a technique he’s used for reading multiple analog sensors with one MCU ADC pin. He was designing a line-following robot and wanted to read several infrared sensors without having to dedicate an analog read … Read more
Gleb Polyakov and Igor Zamlinsky of Atlanta, GA have designed this proportional-integral-derivative (PID) controlled espresso machine. Based upon their observations after reverse engineering a number of espresso units, the pair worked on developing a machine which would be reasonably priced, … Read more
Jim Choate presents this project using the USB IR Toy along with Arduino and Windows 7 Speech Recognition to control Hex Bug robot toys. A link to the C# and Arduino code is included. Via the contact form.
Steve Schuler likes to hack the Spy Video Trakr. His most recent efforts involve adding a Lego grabber arm. He writes: I have added a Lego grabber arm to the Spy Video Trakr. The Trakr is a remote controlled robot … Read more
Algorhythmic has posted a multi-part tutorial at aonsquared describing how to build a voice controlled robotic arm. While recovering from a wrist injury he decided to assemble and experiment with a robotic arm controlled by USB using notbrainsurgery’s protocol. After … Read more
Here’s an entry in the Open 7400 Logic competition: Discrete servo driver. This entry is designed to control RC hobby servos. 8bit parallel BCD code input from a dip switch sets a pulse width between 0-25.6ms (180 degrees of motion). However on … Read more
Parallax is introducing a new robotics platform based on the Propeller microcontroller. Known as Eddie, which stands for Expandable Development Discs for Innovation and Experimentation, the platform consists of dual 18 inch round bases positioned one above the other. The … Read more
Microsoft is sponsoring a robotics design contest known as Robotics @Home. They write: Here’s your chance to show us what you’ve got. Describe that cool idea to us in a PPT, PDF or Word Doc and submit it. If your … Read more
Ejberg.dk has developed this project for a simple ATtiny2313 based servo tester. This device lets you test servos by varying the pulse width between limits of 0.8000 ms and 2.2000 ms selectable through the use of four buttons. While the … Read more
Chris from Pyroelectro is now experimenting with adding a new dimension to this robotic face, an animatronic neck: Having already built the eyebrows, eyes and mouth for our animatron, the final step will be to affix it to a neck … Read more
Chris from Pyroelectro wrote previously about his work developing robotic eyebrows. Now he’s experimenting with adding a new dimension to this robotic face, an animatronic mouth. Here’s another article I thought you guys would enjoy…..this article shows you two simple … Read more
Chris from PyroElectro sends this link to his simple animatronic project using a PIC 18F452: This project serves as an introduction into animatronics by using some off-the-shelf hobby servos as actuators to move a pair of eyebrows on a dummy … Read more
This robot kicking the beer can around in this video is known as DARwin-OP. This the result of an Open Platform Humanoid Project sponsored by the National Science Foundation (NSF) in the United States and developed by RoMeLa at Virginia … Read more
In this video Trossen Robotics debuts their Garden Avenger Robot. David Dorhout, the bots developer writes: A couple of years ago I first saw one of those self contained game systems that consist of just the joystick and the AV … Read more
