Stingray robot uses light-activated rat cells to swim
A new study found that a new robot stingray can swim with the help of unexpected sources: muscle cells extracted from the heart of a mouse. Understanding how to build machines from heart cells may lead scientists to be able to build the entire living artificial heart from muscle cells that behave more like natural hearts, the researchers said. The stingray and related fish have a flat body with long wingslike fins. These fins fluctuate in waves, waves fluctuate from the front to the back of the fins, energy- Effective action to help these fish glide in the water. [ The weirdest six robots ever. Researchers are trying to build a robot that simulates the efficiency and operability of Stingray. When the senior author of the study, Kit Parker, a biology engineer at Harvard University, studied stingray fish, he pointed out that the beating of their wings was similar to the beating of the heart, which inspired him to use the mouse heart -- Muscle cells, he said. Scientists begin by imitating the shape of a Stingray skeleton, which is made of gold and is chosen for its chemical inertia. The bones are then covered with a thin layer of elastic plastic and thicker silicone rubber. Scientists have placed muscle cells in the rat\'s heart on top of the robot. When stimulated, these cells contract and pull the fins down. Scientists want to keep the light of the robot, so they want to avoid pulling the fins back with the second layer of cells. Instead, they say, they designed a shaped bone that stores some energy used to pull the fins and releases them when the robot\'s cells relax, allowing the fins to rise. Robot cells also respond to light through genetic engineering. The researchers used light pulses to turn the robot to the left or right and change the wavelength of the light to control its speed. Scientists are able to control the robot well and guide it through a simple obstacle process where the machine swims at a speed of about 0. At a distance of about 9 kilometers, 06 inch kilometers per second. 85 inches. Contains about 200,000 rat hearts- Muscle cells, robot measures 0. 63 inch long and 10 grams heavy. Researchers say robots swim in liquids containing sugar as fuel. \"It\'s alive, but it\'s not an organism -- \"It can\'t copy, it can\'t copy, we produce in five or six batches, and they live for about a week, maybe less,\" Parker told life science . \". \"The purpose of Parker\'s study is to build alternative organs for sick children,\" he said . \". \"In the end, we want to build a whole heart. We\'re already thinking about making robots with another marine creature. To test our skills. Scientists detailed their findings in the July 8 issue of Science.
