Hajime Sakamoto, the president of the Hajime Research Institute (a Japanese company that has been building humanoid robots since 2002) is unhappy with the world famous 1/1 scale Gundam statue.
Time-lapse photography has the effect of making almost any piece of footage more interesting. I’ve always been fond of the technique, ever since I saw plants wriggling and growing in BBC nature documentaries, or the cinematic vacations Koyaanisqatsi or Baraka (both of which are worth your time, by the way).
Toyota, like any car company, has a number of prototype and concept vehicles in the works at any given time. In the last few years, they’ve been focused on developing smaller, personal mobility vehicles that are tailored to improving the lives of the elderly or disabled. Most of these vehicles are robotic wheelchairs that balance using the inverted pendulum model, named using Apple’s trendy ”i” prefix, like the i-swing, i-real, and in 2003, developed a prototype that would become the i-foot. The prototype stood 180cm (5’8″) tall and weighed 75kg (165 lbs).
Suidobashi Heavy Industry (an impressive name for what is in reality a small group of dedicated giant robot afficionados), is in the process of building the first 3.8 meter (12 ft 5 inch) tall, 4,500 kg (4.9 ton) single-occupant mecha.
In moments, a generic radio-controlled car shifts, turns and becomes an upright mini fighting-machine — able to deliver the twists and punches familiar to those of us who watched the movie Transformers.
In a forest north of Copenhagen, Danish architects Frederik Agdrup and Nicholas Bjorndal of Eentileen used just a computer, a printer and 820 sheets of plywood to build a 125 square meter (1,345 square foot) home in four weeks.
Think hybrid cars are futuristic? How about a hybrid car that has literally been printed out?
Stratasys and Kor Ecologic recently teamed to develop Urbee, the first car ever to have its entire body 3-D printed with additive manufacturing processes
(by printing layers of material on top of each other until a finished product appears).
Some time ago Adrian Bowyer started to build a mixer nozzle for RepRap that would take four coloured filaments and combine them out of a single nozzle.
There are now many different types of aerogels that are flexible and high-strength, some of which are so mechanically robust they can actually be used for structural applications!
Aren’t Aerogels Already Superstrong?
Although it’s true that a typical silica aerogel could hold up to 2000 times its weight in applied force, this only holds if the force is gently and uniformly applied. Also, keep in mind that aerogels are also very light, and 2000 times the weight of an aerogel still might not be very much. Additionally, most aerogels as-produced are extremely brittle and friable (that is, they tend to fragment and pulverize). As a result, structural applications of aerogels were for a long time totally impractical
A simple, example application of the 9DOF MARG sensor array and orientation filter shown in a previous video.
When the angles of the camera pan/tilt/roll unit are controlled to be equal to the angles of the sensor, the camera points in the same direction as the sensor. An example use of this would be to have the sensor fixed to a persons head and the camera look in the same direction as the wearer.
Kåre Halvorsen aka [Zenta] has been building his MorpHex rolling hexapod for nearly a year now, and good things come to those who wait.
After a ton of development and fabrication, [Zenta] finally has his mechanical jellyfish robot rolling and walking around.

There is no other manufacturing technology as diverse as 3D printing. It encompasses many technologies and process and each has different attributes. In terms of conventional approaches, only machining comes close to the breadth and range of options. Yet, even machining is constrained to one core method, material removal with a cutter. 3D printing has no such constraint.
Article explains the different core processes of:
"Electrical experiments are the clearest and most exciting of those offered by physics."

If a combination of a cylindrical magnet and a screw is suspended from the terminal of a battery and a conducting connection is made with the other terminal, then this assembly begins to rotate.
It is not only the simplest but also the fastest electrical motor to construct.
Imagine turning your pictures into 3D models.
Autodesk recently unveiled two pieces of software that allows users to create 3D objects from photos.
SmartPlanet go behind the scenes to bring you the ABCs of 3D printing.
Have you ever wondered how things like inline skate wheels and electric motors spin so smoothly and quietly?
The answer can be found in a neat little machine called a bearing.
Explaining:
- Mechanical Advantage, Torque vs. Rotational Velocity
- Gearing Ratios
- Achieving a Particular Gearing Ratio
- Gear Efficiency
- Direction of Gear Rotation
- Gear Chains (more than 2 gears together)
- Compound Gears
- Gear Pitch
- Gear Types
The WOWModelViewer project is an open source application to create machinima with characters and models form the World of Warcraft MMORPG. One of its features is the ability to export models into various formats, two of them being X3D and X3DOM. The X3DOM option directly outputs an XHTML file with the appropriate header code. In its current released version 7.0.1 r462, only static models can be exported, but an option to export animations as well is already available in the code.
This three-decade-old technology finally becomes accessible and even commonplace.
Lisa Harouni gives a useful introduction to this fascinating way of making things -- including intricate objects once impossible to create.
Lisa Harouni is the co-founder of Digital Forming, working in "additive manufacturing" -- or 3D printing.
3D printing is at a very exciting stage in it’s development.
Here are the reasons why a school should seriously consider using 3D Printing as part of its curriculum.
A single RepRap printer about $1200. These prices are minimal in the scheme of school budgets.
This white paper, It Will Be Awesome if They Don’t Screw it Up: 3D Printing, Intellectual Property, and the Fight Over the Next Great Disruptive Technology, examines how intellectual property (IP) law impacts the rapidly maturing technology of 3D printing, and how incumbents who feel threatened by its growth might try to use IP law to stop it.
