dammitdarrell demonstrates an android app that directly controls servos via a special audio tone from an android phone. No micro-controller or electronic components of any kind are needed aside from a battery.
BlaMule presents the third version of a LEGO robot playing Quarto. With 32 presure sensitive sensors, a solid lego construction and the RCX brick linked to a PC is at least impressive. The maker says that this version is build to win!
samuelosv demonstartes a robotic arm which is controlled by the human's arm movement with accelerometer and gyro. The robotic arm moves proportionally to the movement around one axis of the arm. It is possible with more gyros and accelerometer to add more degrees of freedom.
Scott Sumpter presents an autonomous robot that uses as distance measurement an optical mouse for accurate readings. Actually there are two robots. the first one, equiped with 2 limit switches for object detection, navigates its way around an object, then communicates the path it took back to another robot, which can then avoid the object without sensors. More info can be found here.
Daniel Mellinger from the University of Pennsylvania describes one of his works as "developing controllers for aggressive maneuvers with quadrotor helicopters". In action this means tremendous maneuverability and insane control in turning.
Perching seems simple compared to the double flips and the amazingly precise flight through windows. A UAV showing things to come, enjoy.
robidouille wanted a robot being able move on a horizontal wooden 2 by 4 stud and avoid obstacles found in its way. After several designs he ended up with this 2 arm version that seems to work the best. He is using an Arduino as microcontroller and a couple of Hitec HS322-HD servos. Each arm has 2 lever-switches to detect pressure in front and below. The design looks like a monkey but it works so well i don't see any danger.
Dino Magri, Pedro Ângelo, Ricardo Lobo and Tiago Serra took some cheapo rc cars, ripped out the original pcb and replaced them with arduino in order to drive them with GameCube steering wheel controllers. Next they made a rather large circuit to drive their cars around and voila, a new MicroMachines racing game was born! Of course they couldn't bend to see the cars so the track is viewed via a projector on the wall. The whole thing is amazing but i cant say the same for the driving skills. :). If you want the documentation and the code you can check here with only requirement you know portuguese. If you're interested in the teams works you can check these sites also, labcdmusaxdatelier.
tvbrock08 demonstrates his door unlocker prototype made with an arduino. Using a piezo electric buzzer to detect the knocks, arduino decides whether you are getting in or staying out by giving power to a motor that will open the door. Knocking patern can be changed on the fly by just a press of a button. At its prototype state the project works fine and we wait for the completion.
