But it is time for the miniaturized robots to leave the research laboratories and find useful applications. That is where this work fits in. It is an attempt (with a somewhat small budget) to try to build robots in a mass-fabricated way.”As this was the first test of this fabrication technique, the researchers noted that they encountered some fabrication problems. The single largest problem was to connect the naked integrated circuit to the flexible printed circuit board by the conductive adhesive. Also, some solar cells did not stick due to weak adhesion. At this stage in the production process, the robots were folded manually, but the researchers hope to design a tool to enable a faster and more accurate alignment when folding. Many of these complications could likely be corrected, with the important result being that the microrobots can be assembled using a surface mounting machine, whereas prior robots have usually been manually assembled with a soldering iron.

In the future, the researchers hope to move from building academic prototypes to manufacturing the robot on a commercial basis, which is necessary for overcoming some of the technical issues. By mass-producing swarms of robots, the loss of some robotic units will be negligible in terms of cost, functionality, and time, yet still achieve a high level of performance. Currently, the researchers hope to find funding to reach these goals.“Right now the robots need a new ASIC [application-specific integrated circuit] and some other redesigns to be able to work properly,” Edqvist said.

New evidence suggests earliest trilobites were able to partially roll up their

center_img Explore further Fossils record ancient migrations and trilobite orgies (Phys.org) —A trio of researchers—two from Cambridge University and one from the Chinese Academy of Sciences, has found evidence that suggests that the earliest trilobites were able to roll up their bodies for protection, much as their later ancestors did. In their paper published in the journal Biology Letters, the team describes their examination of a fossil found in Alberta Canada, and how they ruled out other causes for its rolled up position.

Travel shop love

first_imgTravelista, India’s first travel film, photography and shopping festival returns for the second time this October. Dilli Haat will transform yet again into a travel and culture connoisseurs heaven. A host of activities ranging from travel film and photography screenings will be part of the festival along with over 55 stalls of apparel, jewellery, home décor, accessories, kitsch, pop art and vintage on display. Nomadic film screenings under the moon lit sky, funky rickshaws, roadside carts selling your favourite cutting chai and popcorn and colourful art installations will be some of the many amazing attractions of the Travelista festival.  Also Read – ‘Playing Jojo was emotionally exhausting’Travelista aims to establish a platform for formally trained artists, upcoming women designers and entrepreneurs to showcase their talent – over 50 upcoming women entrepreneurs and designers have been represented at Travelista so far.23-year-old young entrepreneur Akshuna Bakshi organised the first edition of the festival by herself in February at Dilli Haat INA. Previously, she has organised a travel film and photography festival in 2012 in London and shot travelogues for UK based travel organizations. While the London festival focused exclusively on films, Akshuna decided to carry her dream forward back home at a bigger scale and took her proposal to Delhi tourism authorities at Dilli Haat.  Also Read – Leslie doing new comedy special with NetflixFor this edition, India’s leading backpacking company, indianbackpacker.com’s Akshay Chhugani has joined hands with Travelista. The festival promises to be an absolute delight for travel junkies, culture vultures, art and shopping lovers! Travelista is also the first festival in India to give a platform to budding travel filmmakers and photographers and showcases their video postcards, travel documentaries and travel shots to the general audience. The festival will have a notable jury from Lonely Planet, BBC and Travel Channel to pick from over 200 travel films and 3000 travel photographs.   The films at the festival are fun, adventurous, colourful and path breaking. While some films explore the untraveled alleys of Middle East and breath-taking sceneries of Europe, others reveal the dangerous trade of diamond mining and poaching in Africa. The festival aims to entertain, educate and surprise the audience through its films & photographs. It even hopes to break the pre-conceived stereotypes people often carry about a destination or culture. A special festival attraction will be the ‘Travel Wall of Fame’ that will showcase photographs of people posing in various destinations round the world. Anyone who is a traveler at heart can send in their pictures of their voyages to the festival team and adorn the wall of fame.WHERE: Dilli Haat, INAWHEN: 11 to13 October, 11 am to 10 pmlast_img read more

Matter Hungary

first_imgThe Hungarian Information and Cultural Centre organised an International artworks exhibition Spirit and Matter- Three Artists- Three Generation by Ilona Lovas, Anna Makovecz and Villo Turcsány from Hungary, curated by Katalin Keserü organised by Anna Bagyó and Cocos Nuciferas by MD Deleep Franco Swiss from France-Switzerland.The opened on January 27 at the lawns and gallery of the HICC, followed by a short performance by János Palojtay (piano) and Dávid Simon (flute). Also Read – ‘Playing Jojo was emotionally exhausting’The two exhibitions were inaugurated by Szilveszter Bus, Ambassador of Hungary, in the presence of François Richier, Ambassador of France. The exhibitions will be closed by the Dipali Khanna, Member Secretary, IGNCA, in the presence of curator, Katalin Keserü and artiste, Villo Turcsány from Hungary followed by Mohiniyattam performance by Hungarian dancer, Brigitta Hegedus at the HICC on February 26. The exhibition will be on view till February 28. Also Read – Leslie doing new comedy special with NetflixSpirit and Matter- Three Artists- Three Generation is an exhibition-cum-performance, curated by art historian, writer and curator Katalin Keserü, organised by art consultant Anna Bagyó, with the participation of three Hungarian woman artists: Ilona Lovas, Anna Makovecz and Villo Turcsány. The three artises, representing three different generations, coexist well with each other. Their works examine the metamorphosis of matter, body and spirit. These evergreen topics of art are translated into the language of contemporary mediums and will be presented as installations, photos and videos. Cocos Nuciferas features spiritual insights with various imageries of Coconut and Rangolis. The artworks by MD Deleep (a Franco-Swiss artist) are an attempt to translate and share spiritual and ethnic emotions, sensations through these intermediaries. Thus, it is important that there exists barely any distance between the viewer and the work. With such participation, there is enough scope for the individuals to enter the specific work-scope and create new relationships between creation, creator and spectator. The artiste’s aim is to work in interaction with the public, resulting in a timeless piece, which everyone can interpret in his/ her own way.last_img read more

Makeup tricks to try out during the monsoon

first_imgAs much as the cool weather soothes your soul after a rough summer, the monsoon is not everyone’s favourite time of the year. Hence, make-up has to be done differently during this season keeping in mind the high level of humidity while you are on the go.Experts say how:* Use minimal foundation on your skin and make sure the focus of your look is on your eyes and lips.* Use a gel liner as it can be easily blended onto your skin for different looks like a definite wing.* Top it up with some bold waterproof mascara and watch your eyes come alive regardless of how dull the skies are.* Matte lipsticks are great, especially long wearing ones, as they reduce touch-up worries. Go for a matte lipstick that keeps your lips moisturised, as they are made to glide on tenderly but with full impact on your lips.* Experiment with the trend – applying lighter colours on the middle of the mouth and blending it out into a deeper colour for a beautiful dimension. It will be matte, but not flat.last_img read more
