May 3, 2006 We suspect the announcement by LEGO that it will release as open source the firmware of the LEGO MINDSTORMS microprocessor (the new NXT brick – the core component of its next generation robotics toolset) will have a considerable impact on the fledgling robotics home hobby marketplace and potentially on general robotic knowledge. LEGO will also release Software, Hardware and Bluetooth Developer Kits to its growing global audience of robotics enthusiasts. The firmware code and three developer kits will be available in August 2006 to conincide with retail availability of LEGO MINDSTORMS NXT.  Read More

May 3, 2006 We’re very excited this week about the prospects for Unmanned Ground Vehicles given the unveiling of Crusher and the US Defense Advanced Research Projects Agency (DARPA) announcing plans to hold its third Grand Challenge competition on November 3, 2007. The DARPA Urban Challenge will feature autonomous ground vehicles executing simulated military supply missions safely and effectively in a mock urban area. Safe operation in traffic is essential to U.S. military plans to use autonomous ground vehicles to conduct important missions. So rapidly have UGVs developed in the last few years thanks to Grand Challenges I & II, we suddenly see the prospect of unmanned vehicles being used in civilian occupations – a driver that never sleeps, obeys all the laws, costs a fraction of a human being’s time. Delivery robots make sense and within a few years our bet is that the technology will be in place. The winner gets far more than just US$2 million, as the leading contenders have found in previous events – the world will beat a path to your door if you can win Grand Challenge III. To win, you’ll need to have your UGV complete a 60-mile course through urban traffic under six hours. The UGV will need to be able to merge with traffic, read traffic signs, navigate roundabouts, busy intersections, avoid running over errant pedestrians, avoid obstacles – just like a normal automobile driver.  Read More

May 2, 2006 Safeguarding the soldier is the key aim of the Unmanned Ground Combat Vehicle – giving soldiers enhanced stand-off capability was the reason DARPA funded the Grand Challenge and backed up again two years later with the second challenge and is now holding the challenge in an urban area – such contests dramatically accelerated research into autonomous navigation and identified the most capable people to for the military to work with. The National Robotics Engineering Center (NREC) is part of the Robotics Institute in Carnegie Mellon University's School of Computer Science, unveiled Crusher last week. Carnegie Mellon vehicles finished a close second and third in the Grand Challenge though everyone knew they were at the bleeding edge of robotics knowledge, the Challenge just confirming it. Crusher demonstrates just what we can expect to see on the battlefield a decade from now. In what might well be seen as an offspring of the Grand Challenge, “Crusher” is a new breed of UGV – an NREC-designed, six-wheeled, all-wheel drive, hybrid electric, skid-steered, unmanned ground vehicle. The bohemoth weighs 14,000 pounds fully fueled, and is designed to carry a 3,000-pound payload – at this 17,000 pound total weight, two Crusher vehicles can be carried by a single C-130H aircraft and dropped into any region in the world. Once on the ground, Crusher can carry up to 8,000 pounds of payload without compromising its mobility – read that as 8000 pounds of smart stuff – any combination of cargo, armour, armaments, or surveillance equipment. Crusher is also designed to withstand extreme terrain, with the ability to take in its stride regular impacts with trees, boulders, fences, tree stumps and ditches at high speed. With six wheel independent drive, Crusher can go up and over almost anything, and if in the process it should get upside down, it moves its wheels to the other side of the vehicle and starts all over again. Crusher's hybrid electric system is silent, using a high-performance SAFT-built lithium ion battery module which delivers power to the six, in-wheel UQM traction motors located in the hub drive system of each wheel. Much, much, more … interesting stuff!  Read More

April 6, 2006 We’ve all held our breath in the movies as the submarine with the good guys in it slides between the mines, touching a chain here and there to heighten the drama. In the future, that scenario will need to be rewritten as it’s likely that an unmanned underwater vehicle (UUV) will be fired from the torpedo tubes well in advance of a minefield and scope out exactly where the mines are. Make that the not-too-distant future because Boeing is already into a second round of at-sea tests of its Long-term Mine Reconnaissance System (LMRS). The LMRS is a 20-foot UUV designed to be launched, torpedo-style, from Los Angeles- and Virginia-class submarines and can survey the murky waters ahead for up to 60 hours. Originally planned for use in detecting tethered and bottom mines, the vehicle is designed to gather data and, upon completion, to home and dock to the submarine's 60-foot robotic arm for recovery back through the torpedo launch tube, enabling operators to retrieve data collected and prepare the vehicle for another launch. The vehicle's intelligence gathering capabilities have been sequentially tested and validated.  Read More

March 23, 2006 To say we think WowWee Robotics has played a pioneering role in the first wave of the consumer robotics revolution is an understatement. Twenty five years from now when the consumer robotics industry is expected to rival the automotive industry in size, Wowwee’s diminutive Robosapien will be seen in the same light as the Model T Ford and the company’s high tech Geppetto, Mark Tilden (pictured with two roboraptors), could well be held in even higher esteem. The price of the company’s “toy” robots belie their capabilities and Robosapien V1 and V2, Roboraptor et al have functionality for which the company could legitimately ask ten times the price – the bargain pricing though has resulted in millions of Wowwee robots being the first to invade the home. The big news is that overnight Evolution Robotics and WowWee announced a strategic alliance to integrate Evolution's ViPR and Northstar technologies into WowWee products. ViPR (Visual Pattern Recognition) provides reliable and fast recognition of patterns, objects, and locations in realistic environments. Northstar, known as "Indoor GPS," is the world's lowest-cost solution for position-awareness for consumer robots, and enables robots to navigate autonomously and intelligently.  Read More

March 15, 2006 After the incredible response to yesterday’s story on weaponised micro unmanned aerial vehicles, it is interesting to note AeroVironment’s significant production milestone of Small Unmanned Aerial Vehicle (SUAV) systems that was announced today. The Raven (RQ-11A), a manpackable SUAV used by the U.S. Army and Special Forces since 2002, has surpassed the 3,000th air vehicle mark for production. The Raven is a 4.2 pound, hand-launched sensor platform that provides day and night, near-real-time video imagery for "over the hill" intelligence, surveillance and reconnaissance in support of a ground commander. Made of Kevlar and costing US$25,000, it has a range of 80 minutes at up to 90 km/h and can venture up to 15 kilometres from its controller. No greater praise can be given than by those who use the Raven and this can be evidenced at the always excellent military website StrategyPage which reports that the Raven is winning what it terms the unofficial “Commando Olympics.” StrategyPage reports that in addition to the cooperation between the commando units of over a dozen countries assembled to pursue Islamic terrorists in Afghanistan and Iraq, there’s a lot of comparing notes – and the most envied high tech gadget of them all is the Raven.  Read More

March 12, 2006 If there was a list of professions least likely to see humans replaced by machines, the barkeeper would logically be on that list. But students in the final year of a computational linguistics and phonetics course at the University of Saarland in Germany have created a robotic bartender to demonstrate how digital language technologies can be combined with robotics. The robotic Barkeeper understands natural language and hence takes orders in exactly the same way as a normal bartender. It has a database of cocktail recipes, and will propose drinks to the customer at the beginning of the conversation. The user can then choose any cocktail by spoken commands, or create their own cocktail by choosing the ingredients. Then while it is making the drinks, it keeps the customers entertained by telling jokes. The Barkeeper has an extensive jokes database, with additional specific jokes about each cocktail and each ingredient.When it serves the drink, it also explains to the customer exactly what the alcoholic content is.  Read More

March 4, 2006 Boston Dynamics has released images and details of BigDog, which it is billing as the most advanced quadruped robot on earth. If that seems like a tall claim, check out this video of BigDog (Caution 27MB WMV) doing its thing by walking over uneven ground, up slopes, over piles of rocks, snow, through water etcetera – though clearly still in development, BigDog is incredibly impressive and we challenge anybody to view the movie and not see BigDog’s future potential as a perfectly-mannered mechanical pony for children, as an all-terrain four-legged “wheelchair” that can take a 90-year-old for a walk over an orienteering course or a mechanical mule to carry all your camping gear into the middle of the wilderness or … much, much more. In short, BigDog is a quadruped robot the size of a small horse, and could equally have been called a robotic mule, because its skill sets are pre-destined to see it pressed into military service as a mule-like carrier companion for soldiers where conventional vehicles cannot go. Initially developed with funding from DARPA, BigDog’s raison d’etre is to carry ammunition, food and supplies into battle. BigDog can walk, run at speeds up to 3.3 mph, climb over rough terrain or up slopes up to 35 degrees and carry heavy loads – currently up to 120 pounds, but as development goes on, that figure might be significantly increased. BigDog is currently annoyingly noisy thanks to power being delivered by a gasoline engine that in turn drives the hydraulic actuation system for its legs. BigDog is much more than a dumb mule however - it is a pointer to the future - a wonderful example of humanity learning from the biomechanics and energetics of animal movement to build better robots that will serve humanity in many endeavours. Go on, check out the video - we promise you'll show all your friends. Check out the article's images gallery to see clips from the video and schematics.  Read More

February 14, 2006 Almost a million industrial robots are in service worldwide, and their numbers are steadily growing. However, most of them are found in the factories of major enterprises. An EU project aims to develop new, inexpensive versions for small and medium-sized firms. The European Union’s SMErobot project – the name is derived from “small and medium sized enterprises”, – include leading research institutes, universities and the top five European robot manufacturers. Its participants have set out to make robots attractive beyond the confines of large-scale industry. “For this to happen, the metal helpers must be completely redeveloped to a certain extent,” asserts Martin Hagele of the Fraunhofer Institute for Manufacturing Engineering and Automation IPA, who is coordinating the project.  Read More
