A researcher has created a better, easier way to solve a big problem for space exploration, space pollution. “Mark Cutkosky has been working on stickers like this for more than a decade. He designs robots and other devices at Stanford University in California. Now his team has built robotic gripper “hands” inspired by geckos. These hands can grasp objects many times their size without pushing them away. The researchers described their results June 28 in Science Robotics.” Cutkosky, thought of this new way and has launched it to the public. The reason why Cutkosky is using gecko’s feet feature is because tape and really any adhesives don’t work in space. Due to space being like a vacuum Cutkosky had to find an alternative. So he went to gecko’s feet, being able to cling onto things easily without being sticky. Geckos are able to do this because they use “...weak attractions between molecules known as van der Waals forces.” Space pollution is the problem astronauts, scientists, and researchers are trying to solve. Space pollution contains remnants of old rocket ships, dead/broken satellites, pieces of small refrigerators, and tiny pieces of other earthly materials. With the clingy cubes, robots are able to stay put when they have to go outside of the spaceship and gather materials. The robots themselves need to grab the big materials faster. Because, if they don’t grab it in time, the remnants can start to collide. When they are colliding the break into much smaller pieces, which starts the circle of repetition. Unfortunately, till the pieces become so small they start to become an even bigger problem for astronauts and scientists in space for them and their spacecraft, and working satellites.

Engineer Mark Cutkosky, has invented a brilliant tool that might just have solved space pollution.
ReplyDeleteIn space there has been a bunch of pollution going from sizes of a beach bowl to a refrigerator. According to the article “Robot grippers imitate gecko feet to help nab space junk” it says “If pieces of this junk collide, they could break into smaller pieces.” If nothing happens all the pollution will become million of tiny pieces and that is very dangerous for spacecraft. But that is no problem for Cutkosky and his team so they came up with an idea to make a robotic gripper “hand” inspired by geckos. The reason why Cutkosky was inspired by geckos is because tape, glue,suction and any adhesive doesn't work since space is a vacuum. So Cutkosky and his crew observed geckos.“Geckos are lizards that easily climb walls. Their feet don’t feel sticky. But they cling to surfaces using weak attractions between molecules known as van der Waals forces.” says the article “Robot grippers imitate gecko feet to help nab space junk". Cutkosky designs robots and devices at Stanford University in California and has been working on these stickers for decades. On June 18 they described and launched their results in Science Robotics. The hands can grasp objects bigger than their size without pushing them away. The team tested the grippers in a Robo-Dome and a 815 pound robot pushed objects around with the grippers. Last summer the grippers took flight and with there several patches of gripping material it stuck to objects smoothly. There may be hundreds of millions bits of junk in space but with the the help of gecko grippers hopefully everything will go great. #17
In this article by Lisa Grossman it talked about robotic gecko grippers*, if you don’t know what that is it is a piece of machinery that can stick to things and grab things in space. You might be thinking a few things like why would they need machinery if they can use tape or glue, but the thing is they can’t because “glues can’t withstand the wide range of temperatures and suction doesn’t work, since space is a vacuum. So instead a Robotics designer by the name of Mark Cutkosky started working with stickers like the Gecko Grippers for more than a decade. These “hands” can grab space litter and other stuff like beach balls. The first test was when 815 pound robots in a “robo-dome” ( a big air hockey table) pushed each other around using only a small square of the gecko gripper gripping stuff.”Gripper hands could be used to repair or move dead satellites, Parness says. Or gripping parts could help miniature satellites called CubeSats hitch a ride on larger spacecraft” The team tested this on cubes, cylinders, and beach balls. The second thing is why would we need sticky things at all in space, well the answer is space pollution. Space pollution is the junk in space. Which is bad because it could crash into cubesats making them unusable and also into more space trash. Which could be solved with gecko grippers. They got the idea from geckos (obviously) because their feet aren’t sticky, they just have hairs and use van der waals forces. So maybe if these gecko grippers work then it will revolutionise space cleaning. #3
ReplyDeleteA researcher solved a large issue for astronauts in space. Mark Cutkosky designed and built a revolutionary device for astronauts. This device imitates a geckos hands and can help astronauts pick up things in low gravity. Mark has been working on this design for more than a decade at Stanford University California. When he designed the device he took inspiration from geckos because of the unique properties they have. Geckos utilize van der Waals forces which allows them to stick to hard to climb surfaces without any sticky substance. Sciencenewsforstudents states that “ Ordinary glue or tape don’t work once you leave the planet - glues can’t withstand the wide range of temperature and suction doesn’t work since space is a vacuum” But geckos can climb with tiny hairs that are on the bottom of their feet. They first tested their design at the Robo Dome this is a giant air hockey-like field at NASA’s jet propulsion laboratory. They used robots with the gecko-like grippers attached to them to push the other robot gently around the field. The next test they did was to see how the devices would hold up in low gravity. They used the gripper on board NASA’s weightless aircraft, the plane flys in arcs like a rollercoaster, and every time the plane dives the passengers are weightless. They were able to stick to smooth objects with a light touch. The device was a success. This device could be useful to astronauts to move satellites or space debris. This invention would revolutionize cleaning debris in space. #10
ReplyDelete“Get a grip. A new robotic tool can grab floating objects in low gravity.”, states the text. A new brilliant invention, Gecko Gripper, is supposed to clean up floating debris in space. “These hands can grasp objects many times their size without pushing them away”. Invented by Mark Cutkosky, a robot designer at Stanford University, California, has been working on stickers for over a decade. The project was inspired by geckos, because of their sticky hands used for climbing. According to the text, “If pieces of junk collide, they could break into smaller pieces”. If nothing happens from then on, it could cause space pollution. Some space pollution can be really effective in outer space, such as beach balls, meteorites, broken rockets, etcetera. Over time the pieces can collide with each other more and more to the point where they are microscopic and not visible to the human eye. Like bacteria, it can be harmful to astronauts and spacecraft. Thankfully, the gecko gripper was almost ready. After being tested in a Robo-Dome, where an 815 pound (370 Kilogram) robot shoved space debris around the grippers, the gecko gripper went into outer space. “This plane flies in steep up-and-down arcs, like a roller coaster. Each time it plunges, the people on board are briefly weightless.”, states the text. Gecko Gripper is like sea patrol, but in outer space, and was a brilliant invention that could make space travel less of a delay with less debris.

Space junk. Dangerous when small, still dangerous when big. The solution isn't glue or tape, in fact those don’t work in space. From the article “Robot Gecko Grippers Nab Space Junk” we learn that glue can’t handle the constantly changing temperatures of space and that suction doesn’t work in space because space is the ultimate vacuum. The only ‘sticky’ thing that would work in space if you brought it up with you would be a gecko’s feet. The article states that gecko’s feet aren't actually stick, in fact they are actually rough and use something called van der Waals force which helps them cling to smooth and rough surfaces. The van der Waals force is a weak attraction between molecules. - #6
ReplyDeleteAccording to the article ¨Robot Grippers Imitate Gecko Feet to Help nap Space Junk¨ by Lisa Grossman. Ordinary glue and tape will not work once you leave earth. Glues cannot withstand the wide range of temperatures and suction doesn't work since space is a vacuum. Geckos are lizards that can easily climb walls even though their feet do not feel sticky at all. They cling to surfaces using weak attractions between molecules known as van der Waals forces. Mark Cutkosky has been working on stickers like this at Stanford University and his team has built robotic gripper ¨hands¨ inspired by geckos. These hands can cling to objects very big without losing grasp or pushing them away. The researchers described their result on June 28 in Science Robotics. The team first tested its grippers in the Robo-Dome. This is like a huge air hockey table at NASA's Jet Propulsion Laboratory in Pasadena. The 815 pound robot lightly pushed another using the gecko gripper. ¨Then last summer, the gecko gripper took flight.¨ Aaron Parness works out of the Jet Propulsion Lab. He and his team tested the gripper aboard NASA's Weightless Wonder aircraft. This plane flies steep up and down arcs like a roller coaster. Each time it dives, the people on board are briefly weightless. The complete gripper hand has many patches of gripping material in an algorithm that allows them to stick to smooth surfaces with just a soft touch. Because of this, gripper hands could be used to fix or shift dead satellites, Parness says. Or gripping parts could help small satellites called CubeSats catch a ride on bigger spacecraft. The team used the hand to grab and release a cube, cylinder and beachball to practice and test if it would be successful since these mimic some of the many different junk that litter outer space. ¨In all, there may be hundreds of millions of bits — some tiny, others the size of refrigerators. If pieces of this junk collide, they could break into smaller pieces. And even tiny pieces can be dangerous to useful spacecraft or to astronauts on the space station.¨ Trash in outer space is just like the trash and debris we have on earth that is bad for the environment and the gecko gripper hand is a perfect solution for space polution.#5
ReplyDeleteLisa Grossman explains how a new robot might help clean space. This robot was inspired by a geckos grip. As you can tell you already could guess what the name of this robot “Gecko Grippers”.In the according to this paragraph,Mark Cutkosky has been working on stickers like this for more than for a long time now. He made robots and other electronics at Stanford University in California. Now his team has built a robot that their hands can pick objects many times their size without pushing them away. The first test in the robo-dome, it's like a huge air hockey table. After that last summer the gecko grippers were sent out to space. The team was released like a beach ball out to outer space.

Imagine you are on a space shuttle trying to glue or tape something down,but it's not working, you proceed to try and try but it is still not working. This happens because space is like a big big vacuum. Well NASA had this problem in space and were determined to find out a solution. The solution is definitely not the first thing you would think…well of course the answer to this was geckos feet! As weird as this may sound this was quite clever. Mark Cutkosky, an engineer came up with this idea “Now his team has built robotic gripper “hands” inspired by geckos. These hands can grasp objects many times their size without pushing them away.” states this NASA blog. Since Geckos and lizards have tiny hairs on the hands and legs it allows them to stick and climb without falling, NASA’s robotics team worked on making a robot that will act like geckos hands,work like gecko hands, and and is also made out of junk such as “old rocket parts and other no-longer-useful” and “hundreds of millions of bits — some tiny, others the size of refrigerators” states NASA.This gecko-feet-like robot isn’t just something to help stick together in space but also can be used to take out space junk in space which is a big pro. I think that this is one of the coolest,weirdest,and extraordinary things NASA’s engineers team has made.

In the article Robot grippers imitate gecko feet to help nab space junk by Lisa Grossman
ReplyDeleteIt talks about how when objects are floating they use a robot gadget that imitates gecko feet which grips and locks items into the hands place. Normal tape and glue don´t work in space and neither does suction since space is a vacuum. Gecko´s are lizards that are known to climb, and while the feet of a gecko doesn´t feel sticky they cling to surfaces using molecule attraction A.K.A van der Waals forces. Mark Cutkosky has worked on gecko feet robot prototypes for over a decade In effort of gripping on to things bigger than their size, and for gripping things that are floating in the air in general. The gripper hands can also be used for fixing satellites and moving dead ones away from drifting in space and breaking even more. The robots collect unwanted space junk and protect astronauts from being harmed or in danger of small pieces of the junk. If space junk were to be inhaled astronauts may have many future problems and that is why these robotic arms are actually very useful. All in all, the article about how we made robotic arms imitating gecko feet shows how much nature can and has given us inspiration.

In the article “Robot grippers imitate gecko feet to help nab space junk” it explains how Mark Cutkosky has been working on a robot that can grab floating objects in low gravity. Mark has been working on this project for over a decade now and has built robot gripping hands inspired by geckos. The robot was made to clean up dangerous space trash outside of space stations and to help astronauts move around the outside of the space station. It can grip onto objects without pushing them away. Geckos can climb walls and their feet cling on to the walls, but their feet aren’t sticky. They use weak attractions between molecules called van der Waals forces. They first tested the gripers in the Robo Dome, a big air hockey table like thing in NASA’s Jet Propulsion Laboratory in Pasadena. A 815 pound robot pushed another robot with tiny gecko inspired grippers. Last summer the gecko grippers went into the air with Aaron Parness and his crewmates who work at the jet propulsion lab. They tested the robot in Nasa’s Weightless Wonder Aircraft. When the plane goes up and down the people on board are weightless for a moment. The team tested the robot by making the gripper grab objects that resemble space junk. The gripper is complete and has several patches of gripping material made to stick on smooth surfaces with a light touch. It now can fix satellites and other material used on a spacecraft. In conclusion, the gecko grippers were a great advance in space technology.
ReplyDeleteThe one above is by #19.
DeleteIn the article by Lisa Grossman she tells us “A new robotic gripping tool can grab floating objects in low gravity”. It took Engineer Mark Cutkosky more than a decade to finally make a product that was successful. It is hard to find objects that will work in space. One reason glue won’t work in space is because the pressure is too high. Another reason has to do with the temperature, glue can’t withstand the very high or very low temperatures in space. You also can't use a suction because space is like a vacuum so the suction won’t be able to resist the force. Mark Cutkosky then came up with a gripping tool that is strong enough to last in space. “The complete gripper hand has several patches of gripping material in an arrangement that lets them stick to smooth surfaces with just a light touch”. Their inspiration for this tool was actually geckos, geckos can climb up basically anything. They don’t have stickiness on their feet at all, it's just natural. “Aaron Parness and his colleagues tested the full gripper hand aboard NASA’s Weightless Wonder aircraft, this plane flies in steep up-and-down arcs, like a roller coaster”. The people aboard the aircraft are basically weightless. #13
ReplyDeleteOn July 28, 2017, Science News for Students posted the article, “Robot grippers imitate gecko feet to help nab space junk.” Matt Cutkosky and his team from Stanford University in California had just made their robotic gripper tools that can grip things and aren’t sticky. For testing, they cooperated with JPL and used their robotic gripper tool on NASA’s “Robo-dome” which Science News for Students states when testing, “This is like a giant air hockey-table at NASA’s Jet Propulsion Laboratory in nearby Pasadena. One 370-kilogram (815-pound) robot gently pushed another around using a small square of gecko gripper.” sciencenewsforstudents.org. Also, they also got an employee Aaron Parness, from JPL and tested the “gecko gripper” on a plane that will change altitudes and when it goes down, the passengers will become weightless for moments. NASA calls their airplane the “weightless wonder.” The “gecko grippers” turned out to be a success because sciencenewsforstudents.org states, “The complete gripper hand has several patches of gripping material in an arrangement that lets them stick to smooth surfaces with just a light touch. ‘Gripper hands could be used to repair or move dead satellites, Parness says.’... The team used the hand to grab and release a cube, cylinder and beach ball. These represent some of the different types of junk that now litter outer space.” Therefore, the idea of the “gecko grippers” is great and will help astronauts be safer onboard spacecraft in the future.

The article states Geckos are lizards that easily climb walls. Their feet don’t feel sticky. But they cling to surfaces using weak attractions between molecules known as van der waals forces. According to the National Geographic “What makes gecko feet stick are tiny hairlike structures on their toe pads called setae,” Robert Espinoza, a biologist at California State University, Northridge, says via email. These setae are divided at the tip into millions of nanoscale structures called spatulae. To test the gripper in zero gravity, they used NASA’s Weightless Wonder aircraft. NASA’s website states The C-9 jet is one of the tools utilized by NASA to simulate the gravity, or reduced gravity, astronauts feel once they leave Earth. The C-9 jet flies a special parabolic pattern that creates several brief periods of reduced gravity. A typical NASA C-9 flight goes out over the Gulf of Mexico, lasts about two hours, and completes between 40 and 60 parabolas. These reduced gravity flights are performed so astronauts, as well as researchers and their experiments, can experience the gravitational forces of the Moon and Mars and the microgravity of space. The gripper was designed to help pick up and clean space junk. NASA’s website claims Although we don’t see space junk in the sky, beyond the clouds and further than the eye can see, it enters low Earth orbit (LEO).
ReplyDeleteLEO is an orbital space junk yard. There are millions of pieces of space junk flying in LEO. Most orbital debris comprises human-generated objects, such as pieces of space craft, tiny flecks of paint from a spacecraft, parts of rockets, satellites that are no longer working, or explosions of objects in orbit flying around in space at high speeds. The gripper is a great concept, I just don’t know how it can catch any of the junk!

In an article by Lisa Grossman titled, “Robot grippers imitate gecko feet to help nab space junk” she states that ordinary glue, tape or basically any other adhesive does not work in space because of the temperatures. Suction cups won't work either because space is a vacuum. This causes a big problem for astronauts. Due to the little gravity in space, there is a lot of space junk floating around like old pieces of metal. It can be very hard for astronauts to collect it but if they don’t, the spacecraft could be at risk of getting damaged. Luckily, Mark Cutkosky has been trying to invent something to solve this problem for more than a decade. Mark Cutkosky designs things like robots at Stanford University. He and his team built robotic gripper “hands” that are inspired by geckos. The article mentions that geckos “cling to surfaces using weak attractions between molecules known as van der Waals forces.” The hands that Mark’s team created could “grasp objects many times their size without pushing them away.” They first tested the grippers at the Robo-Dome, a giant air hockey-like table at the Jet Propulsion Laboratory in Pasadena, California. According to the article, ”One 370-kilogram (815-pound) robot gently pushed another around using a small square of gecko gripper.” Then, the team had the gripper hand grab things that were similar to junk that would be found floating in space. Even though there are millions of pieces of space junk, this new technology will hopefully be able to help pick up some of it. #21
ReplyDeleteGet a grip. A new robotic gripping tool can grab floating objects in low gravity. The grippers could one day help robots clean up dangerous space junk or assist them in climbing around the outside of space stations. A new trick for doing this in the absence of gravity: mimicking gecko feet.Ordinary glue and tape don’t work once you leave the planet. In fact, most adhesives don’t work in space. Glues can’t withstand the wide range of temperatures.

But they cling to surfaces using weak attractions between molecules known as van der Waals forces. The team used the hand to grab and release a cube, cylinder and beach ball. These represent some of the different types of junk that now litter outer space. Space junk includes all of the old rocket parts and other no-longer-useful stuff people have launched into space. In all, there may be hundreds of millions of bits — some tiny, others the size of refrigerators. If pieces of this junk collide, they could break into smaller pieces. And even tiny pieces can be dangerous to useful spacecraft or to astronauts on the space station. Geko A small to medium sized reptile found in warm to equatorial regions of the world. Some 2,000 different species of this lizard exist, in a wide range of colors. These reptiles eat insects, worms and even the occasional small bird. But they are best known for being able to climb slick surfaces, owing to special structures on the bottom surfaces of their feet. Lizard A type of reptile that typically walks on four legs, has a scaly body and a long tapering tail. Unlike most reptiles, lizards also typically have movable eyelids. Examples of lizards include the tuatara, chameleons, Komodo dragon, and Gila monster. 15#
ReplyDeleteThe gecko gripper robot is an advancement for robots and astronauts as it can move space junk and other things, and have the astronauts safe from junk and other hazardous things, as everything orbiting the earth is moving at over 17,000 MPH, which is very fast. The way the robot sticks to surfaces is called a Van Der Waal force, instead of glue or tape, because those don't work in space. Glue cannot withstand the temperatures and tape does not work since space is a vacuum. Putting the robot in the weightless wonder aircraft that nasa owns and puts astronauts in to make them feel what going into space is like. Putting the robot in the aircraft resulted in the most similar aspects of space to the robot, and it was able to perform picking up a cube, cylinder and beach ball, all similar to space junk.

Once the testing was finished they sent it to space to be tested on NASA’s “Weightless Wonder aircraft”, A man named Aaron Parness and his team were the first to test out the gripper hands in space. According to Parness they were able to “move or repair dead satellites” and help miniature satellites called “CubeSats” get onto a larger spacecraft. The second test that they did was grabbing things in the ship. They used a cube, a cylinder, and a beach ball to represent picking up space junk left over by past ships. But if they want to be able to grab space junk with the gripper hands it would be difficult because “If pieces of junk collide they can break into smaller pieces. And even tiny pieces can be dangerous to a useful spacecraft or to astronauts on the space station -#8
ReplyDeleteIn the article by Jonathan Lambert it states “Extreme temperatures, low pressure and radiation can quickly degrade cell membranes and destroy DNA.” If the Cell Membranes don’t stick together they won’t be able to withstand the pressure in space and will end up dying. “Balls of Deinococcus bacteria as thin as five sheets of paper were placed on the outside of the International Space Station''. They were placed out there for 3 years and the microbes ended up living. Panspermia is when Microbial groups drift among planets and into the universe. Akihiko Yamagishi is an astrobiologist. He works at the Institute of Space and Astronautical Science in Tokyo, Japan. He was on the team that sent pellets of Deinococcus Bacteria to space in 2015.
ReplyDeleteBecause of litter in space due to whatever humans put there, NASA created a robot with hands mimicking gecko feet. Why they do this, you may ask. Well, a gecko’s feet have a sticky substance, that are stronger than your ordinary tape and glue in space. According to ScienceNews for Students, they say “Geckos are lizards that easily climb walls. Their feet don’t feel sticky. But they cling to surfaces using weak attractions, “ so because of how their feet were made, NASA did the same for their robot to pick up the trash in the atmosphere. For why their cleaning up space is similar to why we should do the same; Robots can run into even the smallest piece of metal and be considered broken. The same goes for the Earth’s trash, when we inhale smoke, pollution gases, or anything similar, we’re inhaling toxins that could further damage our bodies. (#12)
ReplyDeleteIn the article "Robot grippers imitate gecko feet to help nab space junk", Lisa Grossman explains how a new robot arm with gecko-like feet an help grip things in space. Some people might think, why not use tape or glue? As stated in the article, glue and tape stop working outside earth. Gecko feet don't feel sticky, but the webbed feet can grip easily. Molecules known as van der waals forces is what gives Geckos the ability to cling on to different sided surfaces. The gripper hand was very useful because it did not need a hard grip, it simply needed light touch to grasp objects. The team that built the gripper arm first tested the grippers in the Robo-Dome. According to the text, "One 370-kilogram (815-pound) robot gently pushed another around using a small square of gecko gripper." This arm with gecko grips can be a wonderful creation for NASA and they're astronauts in space. #12
