Climbing the wall is a big challenge for most of us, but it doesn't seem that difficult for robots. Scientists around the world have explored magnetic, hot-melt adhesives, vacuum cups, and bionic gecko claws for years. Ultrasonic jets, micro-acupunctures, electrostatic sticking, and other methods that allow robots to hang on the wall. However, these robots may sound very tall, but when they really do research, they may find that most of the original principles are so simple that almost every elementary school student can think of. The magnetic force needless to say is certainly known as å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ å•¥ Hot melt adhesive Scientists from the Swiss Federal Institute of Technology in Zurich, Switzerland, put forward this idea several years ago, using the characteristics of hot melt adhesives or HMA: when they are heated by a glue gun, solids become viscous liquids, when the viscous liquids Once again, the glue sticks to the wall. Although it takes a long time to process the small spot hot melt (it takes 90 seconds to wait for the adhesive), and its environmental requirements are relatively high, the load-bearing capacity of HMA is still considerable. Introducing a small 4cm square patch will bear 60kg. In addition, scientists from Israel, inspired by the snails, also used a glued form to allow the robot to gain the ability to climb the wall, but this time the watering will only stay in a melted state and it can slowly move upwards. Micro needle In autumn, very rural children go to play in the fields. When they come back, they always bring a lot of unknown seeds of various weeds. The micro needles are similar to this principle. Scientists at the University of California, Berkeley, used this principle to design the robot CLASH, which was designed to pull the vertical or near-vertical fabric surface tight with small spiny toes. In combination with a clever mechanical structure, the small robot with a length of 10 cm and a weight of 15 grams has a wonderful gait frequency of 34 steps, becoming one of the fastest climbing robots available, with the fastest speed of 24 cm per second. Move up. Although CLASH can only climb fabrics, the micro needle principle can be applied to other fields, such as climbing rough surfaces. The following figure shows a rock climbing robot developed by a scientific research team. Each of the 750 tiny claws on each foot can help it firmly grasp the rock surface and climb smoothly. Electrostatic adsorption Electrostatic adsorption is even more familiar to us. When we were young, we took the blown-up balloons and we didn't hesitate to mess up the hair and scrabble around in our heads to see if the balloons could suck on the wall. International Stanford Research Association may be inspired from this aspect, developed a wall climbing robot by electrostatic adsorption. This is a non-limb climbing robot. It relies on a crawler that can generate positive and negative electrodes and is attached to the wall. This robot is light-weight and can be controlled by a remote controller. The material of the crawler can be produced in any non-conductive material. Electrostatic, and suitable for any or smooth or rough surface. Supersonic jet If the first few climbing postures are pediatrics, then the remaining ones are slightly larger. The use of Bernoulli's principle in this supersonic jet-climbing wall is that if the fluid is slow, the pressure is high; if it is fast, the pressure is small. The high-pressure air stream is ejected along the edges of the jaws to form a "vacuum chamber". The gripper can be used to "grab" items that are in close proximity without touching the object. Such robotic grippers are often used to pick up something special, they can be easily broken or need contactless treatment to avoid infection. The figure above shows that the research team of the University of Canterbury, New Zealand developed a supersonic Bernoulli robot's claw that is 5 times more powerful than traditional devices. Its airflow is 3 times faster than the speed of sound, and its strong adhesion can not only satisfy the climb The needs of the wall can even be shuttled across the roof. Bionic Gecko Adhesive When it comes to climbing the wall, you have to mention the gecko, and when it comes to the gecko, you have to mention that it has a universal claw. Gecko's feet have millions of tiny bristles, each of which is only a few microns in diameter, and each end of the bristles is also divided by several hundred pairs of hairs. This large amount of fluff is due to van der Waals forces generated when the object comes into contact, making it able to withstand hundreds of times its own weight. Scientists at Stanford University copied the gecko's toes to create a Bionic Robot Stickybot. Moreover, after years of development, this kind of bionic gecko material has not only been applied to wall-climbing robots. For example, the six matchbox-sized robots we released earlier can pull a 1.8-ton car. It is also a bionic binder. There are a lot of similar wall climbing robots. There are not one by one here.
