ROS.org | Powering the world's robots THE MYSTERY OF HANNIBAL'S ELEPHANTS ARCHEOLOGISTS have tried. Students of ancient climate and ecology have tried, too. But no one has yet come up with a satisfactory answer: Where did Hannibal get the elephants for his heroic march across the Alps to attack the homeland of the Romans? The question was raised anew in the Sept. 6 issue of New Scientist, a British magazine. Derek Ager, a geologist, wrote an article casting doubt on all of the proposed sources of Hannibal's elephants. Once there were elephants nearly everywhere, but by the time of Hannibal's march in 218 B.C. they had already dwindled to the two species extant today, the Indian, or Asian, elephants and the African ones. If he had had a choice, Hannibal would presumably have gone into battle with Indian elephants, which had been used effectively a century before in charging against the forces of Alexander the Great. The bigger and ill-tempered African elephants are distinguished by their larger, fan-shaped ears, flat foreheads and concave backs.
Servos and Robotics | Motor and Power Control | Analog Devices Servo solutions are associated with attaining the highest performance and accuracy of a moving system. In most cases the end solution is a CNC or robot system that operates with high precision and where control of absolute position, along with best torque alignment, is required. Analog Devices' offers a complete solution covering all key components in the signal chain. Hover over the blue blocks to view ADI product recommendations. OpenRTM-aist official website | OpenRTM-aist The Times | Architecture With more than seven applications for every place, architecture is one of the most competitive of the major subjects. Entry grades at the leading universities reflect this, with 15 averaging over 400 points in the latest table. Some universities ask candidates to produce a portfolio of work if they have not taken an art or design-based A level. Bath has regained first place from Cambridge this year, with the best employment record, the most satisfied students and – more surprisingly – the highest entry grades. Training in architecture is a long haul – usually seven years, in which the first degree is but one step on the way. A third of all undergraduates enter architecture degrees with qualifications other than A level or Advanced Highers.

SmartSoft The First Zombie-Proof House Somehow, ritual drunk-conversation concerning team captains for the apocalypse has become a major part of the lives of 20-somethings. Having been matured in the Grandaddy-crowned masterpiece film (put “A.M. 180” on and forget that you have a job) 28 Days Later and the best-selling Zombie Survival Guide, we’re all a little too ready to deal with the 2012 zombie apocalypse of our dreams. “The Safe House,” designed by KWK Promes, starts to get eerily close to something I could work with, if say 200 bludgeoned members of the undead army came over to eat their way into borrowing some sugar. “The most essential item for our clients was acquiring the feeling of maximum security,” begins the designers’ website in the summary of the structure. The house, with its movable walls, has only one entrance, which is located on the second floor after crossing a drawbridge.
Wie WAAS und EGNOS das GPS-System noch besser machen Sehr stark vereinfacht handelt es sich beim WAAS-System (WAAS = Wide Area Augmentation System; Erweiterungssystem für einen großen Bereich) um ein satellitengestützes DGPS (Differenzial GPS). Das heisst, zum Empfang des Signals benötigt man keinen zusätzlichen Langwellenempfänger und es werden zur Signalübertragung keine zusätzlichen und zahlreichen Sendestationen gebraucht. Unterschiede zwischen WAAS, EGNOS und MSAS Das Prinzip ist bei allen drei Systemen das gleiche und die Systeme sind sogar miteinander kompatibel. Selten hört man als Sammelbegriff der Systeme die Bezeichnung SBAS (Satellite Based Augmentation Systems, Satellitengestützte Erweiterungssysteme), obwohl damit eigentlich alle drei Systeme gemeinsam beschrieben würden. Wie die SBAS funktionieren Zweck des Systems Es dürfte nicht überraschen, dass WAAS, EGNOS und MSAS nicht dazu entwickelt wurden bzw. werden, um dem Wanderer oder Geocacher eine genauere Positionsbestimmung zu ermöglichen.

researchers develop a new type of soft, growing robot Imagine rescuers searching for people in the rubble of a collapsed building. Instead of digging through the debris by hand or having dogs sniff for signs of life, they bring out a small, air-tight cylinder. They place the device at the entrance of the debris and flip a switch. From one end of the cylinder, a tendril extends into the mass of stones and dirt, like a fast-climbing vine. A camera at the tip of the tendril gives rescuers a view of the otherwise unreachable places beneath the rubble. Go to the web site to view the video. Kurt Hickman and Aaron Kehoe Robot prototype is soft and flexible and could serve a wide range of purposes. This is just one possible application of a new type of robot created by mechanical engineers at Stanford University, detailed in a June 19 Science Robotics paper. To investigate what their robot can do, the group created prototypes that move through various obstacles, travel toward a designated goal, and grow into a free-standing structure. A growing robot
The Fairy Tale Forest By Ildiko Neer | Travel Klix Hungarian photographer Ildiko Neer began operations in 2009. He draws his inspiration from nature, but a special thrill is wood – the sun makes its way through the trees, the sound of leaves and stunning colors of autumn. All this was reflected in the works of photographer. This amazing photographer really have the eye for a good nature photo. These travel photos, and nature photos are just amazing, this this artist really did a great job. So, if you like these amazing landscapes photos, you are at the right place.
