AiFiLTr0 was frustrated by the wimax signal quality, so he went off making a good wimax antenna. He ended up using a biquad antenna, tuned for WiMax, This was easy but who was going to position it? The servo from a flatbed scanner gave the solution and now the wi-radar is born. The sources and PCB layouts will be posted here soon so stay tuned.
Lorenzo Jamone, Matteo Fumagalli and Giorgio Metta from the University of Genoa, work on a project called "Machine-Learning Based Control of a Human-like Tendon-driven Neck".
For this purpose they builded James, a robot able to orientate its head as needed by actuating its tendon-driven parallel redundant robotic neck.
In Lorenzo's YouTube channel you can watch other videos of James learning to reach and grab objects but for the whole paper you must look here.
HiTechnic manufactures a range of robotic sensors for the LEGO MINDSTORMS NXT. The majority of HiTechnic sensors are certified by The LEGO Company assuring the highest standards of quality and safety. In this video they use the Gyro Sensor along with the HiTechnic IR Receiver to make a self-balancing remote controlled robot. It can be built using parts from either an NXT 1.0 or 2.0 set and will even work with the large RCX wheels.
Building Instructions and programs in both NXT-G and NXC for download are provided here.
If 10-15 years before someone told you that one day you could make with Lego balancing robots would you believed him?
marcimatz shows us the Virtual Robot Experimentation Platform simulating the Expliner robot. Expliner (which is commercially available from Hibot Corporation is able to inspect very high power lines while power is on, and also manages to overcome spacers and other obstacles on its way. The Expliner CAD model is courtesy of Hibot Corporation. You can watch the robot in action here.
Bill Porter starting with code originally written by Shutter of Arduino forums and after adding analog stick support, rewrote it into an Arduino library.
In the video he demonstrates using an Xbee radio module to control his track robot.
For a sum of the library features and details you can check here.
herctrap used an arduino to read from the LFS (Live For Speed) game data such as rpm, speed, gear, turbo pressure, and fuel and made his own dashboard.
From the data he aquired he used 1 servo for the fuel indicator and a unipolar motor for the rpm that actuates also a shift light and one for the fuel indicator. The dashboard completes a 2x16 LCD screen showing current speed and current gear.
Tharit Bunteongjit demonstrates his project Sensibility Space: Ambient Space Controls through Facial Expression.
In his own words "In Sensibility Space+, the experimental project of the concept, the system can sense simple human emotions through facial expression from image processing and analysis with OpenCV in Processing to ident...
horseattack using Lego as build material made a Lego printer with a marker as head. He made also the coding for communicating with his Apple Mac via usb and sent the images.
The video is a bit speeded up but the whole thing seems to work very well and with 75dpi accuracy as the maker says.
Laurens provides us with an easy how-to with simple instructions to make an Lego NXT balancing robot. This works with all NXT sets from older to newer. Check his page and start your own lego pendulum robot right away. :)
