DARPAs twoarmed robot handles tools at less cost

first_img A report in The New York Times now points to signs of progress in achieving robotic hands at a lower cost.. DARPA and partners have evolved into a third phase of the robotic hand project, now toward producing robotic hands for less than $3,000. One of the hands under development comes with three fingers; the other model has four fingers. The project teams think it is indeed feasible to make hands that can accomplish a variety of tasks that will cost less than $3,000. DARPA’s partners in helping to lower costs are iRobot, of Bedford, Massachusetts, and the Sandia National Laboratories in New Mexico.(Last August, Sandia made news with its robot hand in partnership with Stanford. Interestingly, the fact they could produce a hand costing $10,000 was received as good news. Sandia’s press release said that was less than other commercially available robot hands with similar independently actuated degrees of freedom. In the news release of August 12 last year, Sandia National Laboratories said their DARPA-funded hand was cost effective. They had partnered with Stanford for the hardware. The Sandia Hand offered 12 degrees of freedom, for about $10,000 in low-volume production. The cost reduction was considered a breakthrough.)Last month, however, the Pentagon, with its continued efforts toward lower cost artificial hands, released a video of a two-armed robot using a tool to change a tire. Experts were impressed that the hand could mimic finer movements, and were also impressed that the creators had been working with a more modest budget. DARPA hopes to accomplish hand movements with the dexterity that can detect an IED by touch. The scenario in its vision is for the robotic hand to open a bag and recognize such objects by touch.

A research project has been under way to develop artificial hands; the main goals have been of an economic as well as technical nature; DARPA has been looking for robotic hand systems that offer not only optimal dexterity but can also come at a lower cost than in the past. The high costs associated with effective robotic hands have been $10,000 and up.

Tracing histories

first_imgWhat is National Museum? And when, why and how are such museums made? Today, almost every country we visit has a museum and a gallery that it calls ‘National.’ Within these institutions, we are able to trace a history of the nation through art. National museums are so widely present that it might come as a surprise to learn how recently they took this form.This, to a stream of thought, suggests a close relationship between political sovereignty and national self-representation in the cultural sphere. So what all could they be? To answer all the question that rises in your mind about this curious hyperlink, National Museum, Delhi,  is organising the 17th NM lecture this Friday evening. Renowned art historian, Kavita Singh of Jawaharlal Nehru University will be delivering a lecture on this subject. Also Read – ‘Playing Jojo was emotionally exhausting’Against the backdrop of the global history of national museums, this lecture will discuss the formation of the National Museum in Delhi (founded 1948), and put it in dialogue with two other National Museums of South Asia: the National Museum of Pakistan in Karachi founded in 1948, and the National Museum of Bangladesh, formed in 1973. When: May 29Where: National Museumlast_img read more

Prolonged sitting linked with fatty liver disease

first_imgProlonged sitting such as watching TV and using the computer and other devices as well as reduced physical activity may increase risk of non-alcoholic fatty liver disease (NAFLD) that may potentially lead to liver failure and death, new research has found.“We found that prolonged sitting time and decreased physical activity level were positively associated with the prevalence of NAFLD in a large sample of middle-aged Koreans,” said lead investigator Seungho Ryu from Sungkyunkwan University School of Medicine, Seoul, South Korea. The researchers studied records of nearly 140,000 Koreans who underwent a health examination between March 2011 and December 2013.  Physical activity level and sitting time were assessed using the Korean version of the international Physical Activity Questionnaire-Short Form.  Also Read – ‘Playing Jojo was emotionally exhausting’The presence of fatty liver was determined using ultrasonography. Of the people studied, nearly 40,000 had NAFLD. Importantly, the researchers found that both prolonged sitting time and decreased physical activity level were independently associated with increasing prevalence of NAFLD.Remarkably, these associations were also observed in patients who were not obese. “The message is clear, our chairs are slowly but surely killing us. Our body is designed to move and it is not surprising that sedentary behavior, characterised by low muscle activity, has a direct impact on physiology,” Michael Trenell, professor of metabolism and lifestyle medicine at Newcastle University in England said.“With a dearth of approved drug therapies for NAFLD, lifestyle changes remain the cornerstone of clinical care,” Trenell noted.last_img read more

Aquatic treadmill found effective for stroke patients

first_imgWalking on an underwater treadmill was found to be more effective than walking on a conventional treadmill for patients in rehabilitation after a stroke, according to a study.The findings stated that aquatic treadmill exercise may be a useful option for early intensive aerobic exercise after subacute stroke, as it may both improve their aerobic capacity and maximise functional recovery.The study included 21 patients recovering after a stroke where all patients had some walking ability, but with impaired leg movement on the side affected by the stroke. The patients underwent two exercise tests: one on a conventional land treadmill and one on an aquatic treadmill, submerged in water up to their chests. Also Read – Add new books to your shelfIn both tests, walking speed and slope were gradually increased until the patients felt they could not go any further. Measures of exercise capacity were compared between the two tests. Two key measures were higher on the aquatic treadmill test: maximal oxygen consumption (VO2max), reflecting heart and lung function during exercise; and metabolic equivalents (METs), reflecting energy use.Heart rate was not significantly different, but was related to oxygen consumption on both tests. Also Read – Over 2 hours screen time daily will make your kids impulsiveEven though their exercise performance was higher on the water treadmill, patients felt they were not working as hard as on the land treadmill, based on a measure called rating of perceived exertion.“This improved performance may reflect the fact that the aquatic treadmill exercise involved the fluid resistance of the water environment,” said Bo Ryun Kim, a researcher at Jeju National University Hospital in South Korea.Early intensive aerobic exercise training might be beneficial in the early weeks after stroke. Treadmill walking is commonly recommended, but may be difficult or impossible because of decreased muscle power. The buoyancy provided by water reduces musculoskeletal impact while allowing combined aerobic and resistance exercise. Exercising in water also has the psychological benefit of freedom from the fear of falling.Aquatic treadmill exercise may not only improve baseline functional status and functional recovery during the subacute period, it may also enhance social participation and quality of life during the chronic stroke period, the researchers suggested, in the paper published in the American Journal of Physical Medicine and Rehabilitation.last_img read more

Malda hospital ransacked after patients death

first_imgMalda (WB): Panic gripped Malda Medical College & Hospital on Wednesday when a mob, infuriated by the death of a local doctor for alleged medical negligence, went on the rampage causing damage to the property, police said.

Childhood trauma may trigger physical pain in adulthood

first_imgDo you want your children to be happy when they grow up? If yes, then you have to make sure that they are not experiencing any kind of trauma as a child. A new study, including an Indian – origin researcher, suggests that childhood trauma or adversity may trigger physical pain in adulthood. The findings, published in the Journal of Behavioural Medicine, suggested that experiencing trauma or adversity in childhood or adolescence was linked with mood or sleep problems in adulthood. Also Read – Add new books to your shelf”The findings suggest that early life trauma is leading to adults having more problems with mood and sleep, which in turn lead to them feeling more pain and feeling like pain is interfering with their day,” said co-author Ambika Mathur from the Pennsylvania State University.But the connection was weaker in those who felt more optimistic and in control of their lives. “The participants who felt more optimistic or in control of their lives may have been better at waking up with pain but somehow managing not to let it ruin their day,” Mathur added. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe findings build on previous research that suggests a link between adult physical pain and early-in-life trauma or adversity, which can include abuse or neglect, major illness, financial issues, or loss of a parent, among others, the researcher said.For the current study, researchers recruited a diverse group of 265 participants who reported some form of adversity in their early lives. They answered questions about their early childhood or adolescent adversity, current mood, sleep disturbances, optimism, how in control of their lives they feel, and if they recently felt pain. They found that while participants who showed these forms of resilience didn’t have as strong a connection between trouble sleeping and pain interfering with their day, the resilience didn’t affect the intensity of pain.last_img read more

Saffron workers try to make Bashirhat bandh a success obstruct traffic train

first_imgKolkata: Following the day-long drama on Sunday, BJP workers on Monday forcefully tried to make the 12 hour Bashirhat strike a grand success. BJP workers put up road blockades and obstructed train services which resulted in tremendous harassment for the daily commuters.Since morning, several road blockades were put up across the Bashirhat area to obstruct normal traffic. Near Kachithuba More, two rallies of Trinamool Congress and BJP came face to face, which resulted in a scuffle. BJP workers put up tree trunks to block the roads. In some places, BJP workers also burnt car tyres to obstruct normal traffic. Even some examinees of West Bengal State University (WBSU) were obstructed while going to the examination centres. Despite repeated requests, BJP workers did not bother to hear their plea. Later, with the help from the local residents, the students were able to reach their examination centres just before commencement of the examination. BJP workers also locked the gate of Taki Municipality on Monday morning. Apart from the road blockades, BJP workers obstructed train movement on the Barasat-Hasnabad section of Eastern Railway’s (ER) Sealdah division. At around 7 am on Monday, a group of BJP workers obstructed train movement at Bhyabla Halt railway station. At around 9:10 am, obstructions were put up at Haroa Road railway station and at 9:20 am in Hasnabad railway station. For almost three hours, the obstruction continued. As a result, daily commuters and office-goers faced immense harassment. At around 11 am, the obstructions were cleared and normal train movement commenced. During the obstruction period, truncated services were on between Sealdah and Lebutala. On the other hand, a team from Central Intelligence Branch (IB) visited Bhangipara and collected information about Saturday’s clash. The IB officials also met with the families of the deceased persons. They reportedly took some pictures of the area and left.last_img read more
