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.

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

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.

This robot demonstrates iPhone to Lego Robotics communication via the Safari web browser and the Lego NXT Light Sensor. Visit www.battlebricks.com for full building instructions.

This robot draws portraits, elaborating photos and images. The software on the PC is developed under MATLAB®, following the ideas of Claude Baumann and his students at www.restena.lu (Erik’s XY plotter). The hardware is LEGO MINDSTORMS NXT® and a soft tip pen. Made by Daniele Benedettelli in 2008. More details at robotics.benedettelli.com
