Study advances ‘mind reading’ technology

Scientist at MIT’s Computer Science and Artificial Intelligence Lab have already developed an application where a person can guide robot with their brainwaves.  For now though, the MIT technology is limited to simple binary activities such as guiding a robot deciding between two choices. With the goal of complex human-robot interaction is the next major frontier for robotic research,  it appears that Carnegie Mellon University’s  latest research led by Marcel Just, builds on the pioneering use of machine learning algorithms with brain imaging technology to “mind read.”  The study offers new proof that the neural dimensions of concept representation are...

The Self-Powered Driving Potato Pet

Many of us young science geeks dabbled with magnets and electricity.  We learned that you can attach a copper and zinc electrode and make yourself a low current (output around 0.4 V at 0.6 mA) potato battery to power a light bulb, thanks to the presence of electrolytes.  Then you have an over achiever like video game developer and inventor Marek Baczynski, who took that idea several steps deeper.  Marek built what could be the world’s first autonomous potato, and the ultimate house-pet, which he’s dubbed ‘Pontus.’. The design of the self-powered spud revolves around collecting the potato current using an...

New algorithm designs optimal origami patterns to produce any 3-D structure

18 years after the original breakthrough, a team of engineers have a universal algorithm for folding origami shapes that guarantees a minimum number of seams.  In a 1999 paper, Erik Demaine, then an 18-year-old PhD student at the University of Waterloo, in Canada, described an algorithm that could determine how to fold a piece of paper into any conceivable 3-D shape.  It was a milestone paper in the field of computational origami, but the algorithm wasn’t  very inefficient. Oragami Algorithm Perfected Dr Demaine, now an MIT professor of electrical engineering and computer science, teamed up with Tomohiro Tachi of the University...

Shape of Bird Egg Indicates Flying Ability

We know birds come in many sizes and shapes, so it’s no surprise that their eggs would too. It has been speculated in the past that egg shape could be linked to making incubation more efficient.  Aristotle theorized that long, pointed eggs are female while more rounded eggs are male.  Other theories were tied to environment such as cliff-dwelling birds lay conical eggs that roll in tight circles, so as to not drop out of the nest. A new Study offers a Simpler Explanation Evolutionary biologist Mary Caswell Stoddard of Princeton University and her team examined more than 49,000 eggs...

Construction robot can lay bricks six times faster than a human

A New York-based company called Construction Robotics has developed a one-of-a-kind robot called the SAM100 (Semi-Automated Mason) , that can lay 3,000 brick a day.  For comparison, a human bricklayer will average around 500 bricks per day. The average efficiency of 3,000 bricks per day,  breaks down to about 4.5 cents per brick.   Designed to work in masonry construction the SAM100 assists with the repetitive and backbreaking  task of lifting and placing each brick. Construction has been a difficult industry to automate because of the customized work it requires, but the SAM100 is designed to work with the onsite mason.  SAM’s human partner...
