This 3D scanner is designed to scan a design made out of lego blocks. The results of the scan appear at aproximately 3:30. It scans by positioning its probe above the apropriate block, then reading how many times it is able to lower the probe before it is stopped by a block. The scanner outputs the data into a text file, so that it can be used in other programs.

Here is my redesigned robot now with no more modified parts, we coukd say he is now ‘pure’. I have posted a prototype development video it is now available but it is 9min long so watch only if interested on how i made wall-e pure! ,, This is the best ‘show me’ video of all my Lego Wall-E NXT – it’s wall-e at it’s best – it no longer has modified lego gears – it has eyes featuring emotion moves – it runs an updated nxt-g program using the new PFE block for better PF motor control – it has no commercial music – and you don,t here me talking !! Part listing can be found in this ‘tutorial’ forums.trossenrobotics.com Thanks for watching sharing and commenting.

Chapter 8 from the book LEGO MINDSTORMS NXT One Kit Wonders. This chapter introduces building and programming instructions for a fully autonomous grabbing vehicle. What looks so simple in the video isn’t all that simple. How do you program a robot to find the closest object in range? How do you grab and lift it with just one motor? You’ll find all of this in the book. The creative minds behind the NXT Step blog (thenxtstep.com) are back with a brand new collection of innovative robots. LEGO MINDSTORMS NXT One Kit Wonders is packed with building and programming instructions for ten exciting robots. The book dives headfirst into the creative thrill of robot-building with models like Grabbot, a robot that finds, grabs, lifts, and moves objects autonomously; Dragster, a super-fast drag racing vehicle; and The Hand, a simple robotic replacement hand to protect you from those dangerous cleanup jobs, like picking up your brother’s dirty gym socks. To further fire your imagination, you’ll also learn how to build a self-parking car model, an M&M sorter, a punchcard reading robot, a bike, and a realistic BobCat. Step by step building instructions make it simple to construct even the most complex models while the detailed programming instructions teach you how a NXT program really works. All of the models in the book can be built with just the basic NXT Retail kit; there are no extra parts to locate or buy. Armed with the knowledge you gain from this book, you’ll be inventing your …

This should be the first project on YouTube that is based on the new NXT Temperature Sensor (9749). The reading range of this “giant” thermometer was intentionally limited from -15 to 60oC to facilitate the design of this construction. However, the actual reading range of the digital NXT Temperature Sensor is much wider (from -20 to 120oC or from -4 to 248oF). Reading resolution is one decimal point (eg 24.4 degrees). The new Temperature Sensor has a long metal tip (about 64mm). The total sensor tip length, including the plastic “nose”, is about 77mm. The difference with the rest common sensors (such as lignt, US, sound etc.) is that cabling is fixed, meaning that there is no connector socket at the back of the sensor. Cable length is about 51cm. Programmed on the new NXT-G 2.0 (with Data Logging), while the NXT Brick firmware was upgraded to V1.26 (instead of 1.05). web.mac.com

Introducing the first robot which uses LEGO NXT components (motors, wheels, …) and which is not driven by the standard NXT “brain” but it is instead driven by Arduino ( www.arduino.cc ). More information: www.arduino.cc www.scribd.com www.scribd.com Comment here: www.arduino.cc

Fifth in the www.motocube.com line of Ball Lego Ball throwers, this one manages about 30ft. Sadly I don’t have a 30ft large room to test it in, so this is all you get.

Visit web.me.com for more pictures. The Pirates and the NXTfied Theater: – One Intelligent NXT Brick – One NXT Rechargeable Battery – Three NXT Servo Motors – One NXT Light Sensor – One NXT IR Link (HiTechnic) – Two Power Functions IR Receivers – Two Power Functions Light Sets – Four Power Functions M-Motors – One Power Functions XL-Motor – Three Power Functions Battery Boxes – Three Power Functions Extension Wires …plus some more LEGO bricks and pieces Special thanks to my wife for the idea of flying seagulls! I have adopted this “NXTfied” expression from my LEGO bro from Canada ( bazmarc/bazmati, www.youtube.com ). Thanks bro!

Tetris-Bot is a Tetris-playing robot. Jay Leno would say “How lazy are we getting? Now robots play games for us!” Well, not exactly, but I agree, we are getting lazy. I made it in order to engage my kids in a fun and educational project. Tetris-Bot consists of a camera, a TI DM6437 DSP board (running my embedded vision and artificial intelligence algorithms), and a three-finger NXT robotic hand (that presses the keys on the computer keyboard). I was inspired by the NXT Rubik and Sudoku solvers and the Segway-like NXT robots. Unlike them, Tetris-Bot is not an NXT-only system, because the Brick has a limited input bandwidth. That’s why I use a TI DM6437 DSP board to analyze the images coming from the camera, recognize the new shape, and find the best place and orientation for it. The instructions are communicated to the NXT robotic hand via LEDs on the board. HOPE YOU LIKE IT !!!
