The consumer electronics show CES is this week so we are probably going to see a couple new 3D printers announced. MakerBot has been teasing a new version of their Thing-O-Matic and today 3D@Home announced their Cube printer. The printer will cost $1,299 and print standard .STL files to print out ABS plastic models. 3D@Home also plans to offer a print on demand service for larger models.
Hyperspectral imaging, also called imaging spectroscopy, is a method of obtaining the spectral content of each pixel in a 2D image. The spectral data can be used into identify the chemical compounds or materials. Up till now hyperspectral imaging devices have been very expensive, starting at around $25,000 dollars. Engineers at the Vienna University of Technology and the University of Arizona have shown that they can perform CTIS spectral imaging using an unmodified consumer camera. The device they have developed can be used in a hyperspectral imaging mode that allows the spectral measurement of a whole image with up to 5-nm spectral resolution and 120 x 120-pixel spatial resolution and can be built for under $1000.
Swiss architects Gramazio & Kohler and Raffaello D’Andrea are a fully automated construction project at the FRAC Centre in Orléans, France that uses flying robots to assemble a six meter high tower constructed of 1500 polystyrene foam bricks. The exhibit lasts from up to February 19, 2012. The same team previously used a robot called "R-O-B" to build a looping wall in New York and the award-winning Structural Oscillations installation at the 2008 Venice Architecture Biennale.
FMC Technologies, Inc. (NYSE: FTI) announced today that it has given notice to exercise its purchase option for the remaining 55% of outstanding shares of Schilling Robotics LLC ("Schilling"). The transaction is expected to close on or about March 30, 2012. FMC purchased its existing 45% interest in Schilling and obtained the purchase option in 2008. Schilling is a leading producer of remotely operated vehicles ("ROVs"), ROV manipulator systems, control systems and other high-technology equipment and services for oil and gas subsea exploration and production. FMC and Schilling have collaborated on a variety of projects and technology advances over the past three years, including an innovative control system for Petrobras' Congro/Corvina project that will use subsea robotics technology to operate the manifold and separation station valves. "We are pleased that Schilling will become part of FMC," said John Gremp, Chairman, President and CEO of FMC Technologies. "Their technologies will help us develop additional solutions to further strengthen our subsea leadership position."
Stratasys is now offering monthly leases options for the uPrint SE 3D Print Pack and the uPrint SE Plus 3D Print Pack. Monthly lease packages are USD $290 for uPrint SE and USD $380 for uPrint SE Plus. Besides the printer, the 3D Print Packs include startup supplies, a support-removal system, and cleaning agent.
Aldebaran Robotics just released a promo video for their next NAO robot. The new model includes 2 cameras, 4 microphones, sonar rangefinder, 2 IR emitters and receivers, 1 inertial board, 9 tactile sensors, and 8 pressure sensors. NAOqi, their proprietary embedded software, provides functionality for task such as speech recognition, object recognition, and access to all the sensors. Code development can take place in Windows, Mac OS, or Linux and be called from many languages, including C++, Python, Urbi, and .Net.
Humans are good at recognizing full facial expressions which present a rich source of affective information. However, psychological studies have shown that affect also manifests itself as micro-expressions. These are very rapid 1/3 to 1/25 second involuntary facial expressions which give a brief glimpse to feelings that people undergo but try not to express. Researchers at Oxford University and Oulu University are developing software that can recognize these ‘micro-expressions’. The initial experiments do indicate that the approach can distinguish deceptive from truthful micro-expressions, but further experiments need to be conducted to confirm it.

Professor George Whitesides, Robert Shepherd and their colleagues from Harvard University have designed a prototype soft, agile robot capable of crawling and squeezing under obstacles current rigid robots are can't handle. The flexible robot motion is controlled by a series of chambers within the 'elastomer' layer that can be inflated with compressed air. The air is fed through tubes attached to the robot.
FroboMind is a conceptual architecture for field robots. The idea is to use the same generic architecture on all field robots and hereby maximizing efficiency, reliability, modularity, extendability and code reuse. FroboMind is open source and is implemented in Robot Operating System. The project includes ASuBot , a research project focusing on weeding in organic orchards, Armadillo , a tracked toolcarrier within precision navigation in row crops, Casmobot , a semi-autonomous slope mower, and Hortibot , a tool carrier capable of traversing a field of row crops.
Boeing video showing its Unmanned Little Bird helicopter landing autonomously on a trailer moving along a runway at speeds up to 15 knots. The test was part of a program with France's Thales and DCNS to demonstrate technology for unmanned VTOL deck landings and take-offs on moving ships.
Here is a video of some of the highlights from The International Micro Air Vehicle Conference and Competition held in September. The competition part of the conference required the tiny autonomous flying robots perform missions in at an indoor and outdoor tasks like collecting objects from within a structure, popping balloons or dropping objects in specific locations. A summary of all the aircrafts that participated are available in this pdf.
Ideas in Action is a weekly PBS program hosted by Jim Glassman. A recent episode focused on the future of the American economy and the role of intelligent computers and robots will play. His two guests were Martin Ford, author of "The Lights in the Tunnel: Automation, Accelerating Technology and the Economy of the Future" and Dr. Robin Hanson, Associate Professor of Economics at George Mason University. The entire episode is available here .
Joe Jones, a co-inventor of iRobot’s Roomba vacuum cleaning robot left iRobot to found Harvest Automation along with three other industry veterans. Their first product is a small wheeled robot that picks up potted plants and move them from place to place. For nurseries that grow or distribute ornamental plants these task are labor intensive and the growing demand makes finding the human labor required difficult. The robot is being tested now in a few nurseries and Wired has a more detailed article here .
A research project at Harvard aims to demonstrate an autonomous multi-robot systems capable of the construction of 3D structures. The hardware comprises a mobile robot and specialized passive blocks; the robot is able to manipulate blocks to build desired structures, and can maneuver on these structures as well as in unstructured environments. To illustrate the robot’s ability to perform complex tasks combining these functions, they demonstrate it autonomously building a ten-block structure significantly larger than itself. The full paper can be found here .
From the video its hard to tell what technology is behind this robot but heres the Google translation of the press release: Communication robots for the elderly "Nodding Kabochan SMILE SUPPLEMENT ROBOT" Launched mid-November! Pumpkin is not nodding, communication robots for the elderly in the shape of a little boy. The reaction of five sensors that are built, or nodding, He makes a variety of chat depending on the season. To take advantage of robot technology, the elderly, who also receive care, How to care for, and further engaged in the business who care, safe delivery and a smile will help to improve life.
