How GoPro for Beetles Robotic Camera Backpack Developed for Insects and Tiny Robots Works

 


The main character in the movie "Ant-Man" can travel and shrink in size by flying on the back of an insect. Now, researchers at the University of Washington have made a small wireless steerable camera that can also ride on an insect, giving everyone a chance to see the world through the eyes of Ant-Man. 


The camera is mounted on a mechanical arm that can pivot 60 degrees and sends video to a smartphone at 1 to 5 frames per second. With this, a viewer can track a moving object or take a high-resolution panoramic picture with little effort. The team mounted this system on top of live beetles and insect-sized robots to demonstrate its adaptability. It weighs about 250 milligrams, or one-tenth of a playing card. 



A tiny camera made by University of Washington researchers can be attached to an insect-sized robot. 


S H Y A M Go L A K O T A, senior author and UW associate professor in the Paul G Allen School of Computer Science & Engineering, stated, We have created a low-power, low-weight, wireless camera system that can capture a first-person view of what’s happening from an actual live insect or create vision for small robots. Despite its significance for communication and navigation, vision at such a small scale is extremely challenging. Wireless vision for small robots or insects had never been possible before our work


Normal little cameras, for example, those utilized in cell phones, utilize a great deal of ability to catch wide-point, high-goal photographs, and that doesn't work at the bug scale. Even though the cameras themselves are small, the batteries they need to work make the system too big and heavy for insects or robots of insect size to carry around. Therefore, the team learned from biology. 


S A W Y E R F U L E R, a co-author and U W assistant professor of mechanical engineering, stated, "Like cameras, animals' vision requires a lot of power". Compared to larger animals like humans, flies only use 10 to 20% of their resting energy to power their brains, the majority of which is spent processing visual information. To assist with reducing the expense, a few flies have a little, high-goal district of their compound eyes. In order to steer where they want to see more clearly, such as when they are pursuing prey or a mate, they turn their heads. Having high resolution across their entire visual field saves power


Using a mechanical arm, the robotic arm can sweep across a field of view. Framework is controlled by means of Bluetooth from up to 120 meters away through a cell phone


In addition, they created the smallest terrestrially powered autonomous robot with wireless vision in the world. The tiny robot moves by using vibrations and uses about the same amount of power as low-powered Bluetooth radios


Although the researchers acknowledge that this technology comes with a new set of privacy risks, they are enthusiastic about the potential for lightweight and low-power mobile cameras. 


Go L A K O T A stated, "As researchers, we strongly believe that it is really important to put things in the public domain, so people are aware of the risks and can begin coming up with solutions to address them". 


According to the researchers, potential uses could include studying novel environments and biology. The team hopes that future versions of the camera won't need as much power, won't need batteries, and might even be powered by solar energy. 


This is the first time we have been able to see a beetle from the back while it is moving around. There are numerous inquiries you could investigate, such as How does the beetle response to various environmental stimuli? Lyre stated, Insects, on the other hand, are capable of traversing rocky terrain, which is extremely challenging for robots at this scale. Therefore, this system can also assist us by allowing us to view or collect samples from difficult-to-navigate areas

What Is Difference Between Chia Seeds And Flaxseed

Image
  Certain seeds have gained a reputation as superfoods in recent years. Examples include the well-known chia and flax seeds. Both have been linked to health benefits such as a healthier heart, lower blood sugar levels, and protection against certain types of cancer. However, many people wonder which of the two seeds is actually the healthiest. Both are extremely rich in nutrients. To answer this question, this article looks at the scientific evidence that supports each The Saliva Hispanic plant, more commonly referred to as the chia plant, is the source of the tiny oval-shaped chia seeds. Chia seeds are slightly larger and flatter than flax seeds. Flax seeds, on the other hand, have a slightly nuttier flavor than chia seeds. However, incorporating both kinds of seeds into a variety of dishes is simple Nutrition comparison Comparative analysis of the nutrients present in chia and flax seeds The major nutrients contained in a 1-ounce (28-gram) serving, or approximately 4 tablespoons,...

Overconsumption of Common Red Food Dye May Lead to Inflammatory Bowel Disease

Image
  Allure Red AC, a synthetic dye found in popular foods like Skittles, Doritos, Gatorade, Jell-O, and Fruit Loops, has been linked to an increased risk of developing inflammatory bowel diseases (I-B D S) such as Crohn's disease and ulcerative colitis if consumed frequently. The dye, also known as FD & C Red 40 and Food Red 17, is thought to have negative effects on gut health and increase inflammation, according to a small study done on laboratory mice. The study, which was recently published in Nature Communications, found that the additive directly breaks the gut barrier, which helps keep bacteria from getting in, and that it also makes more serotonin, a hormone and neurotransmitter in the gut. According to the report, this reaction alters the microbiome of the gut, making people more likely to develop inflammatory bowel conditions. What we have found is striking and alarming, as this common synthetic food dye may be a dietary trigger for I-B D S, said senior author W-A L-I U...

Border violence displaces 76,000 in Lebanon: Hezbollah

 The International Organization for Migration (IOM) of the United Nations reported on Friday that nearly three months of nearly daily fighting along the border with Israel had resulted in the displacement of more than 76,000 people in Lebanon. The boundary region has seen a flood of viciousness since early October, with blow for blow trades of fire forging ahead with Friday between Israeli powers and Hezbollah. In a report distributed on Thursday, the IOM said that the heightening had uprooted 76,018 individuals, predominantly in areas of southern Lebanon lining Israel. More than 80% of the dislodged Lebanese are remaining with family members, as per the report, and just two percent housed in 14 aggregate sanctuaries spread across the south of the country, predominantly in the seaside city of Tire and in the Hasbaya locale. The remainder, according to the UN agency, have relocated to homes or apartments further from the border. Cross-line brutality has left 175 individuals dead in ...
