The distance between reality and sci-fi is sometimes very close.
When you mention Disney's movie "Super Marines," you may not remember, but when it comes to the character called "Baymax" in the movie, you will definitely think of the soft and thoughtful robot, which is not only understanding. It can also help people treat diseases, and is an ideal partner for many family robots. But have you ever thought that one day it will really be made?
Recently, scientists from the Disney Institute have produced such a robotic arm in the laboratory. It not only has soft hands, but also cleverly grabs objects. It also has a soft body like the white of an animation, and has abandoned us. Think of the robot's cold strangeness, we might as well take a look at this special robotic arm.
According to the official statement, this robotic arm is actually composed of two parts: the palm and the joint. In general, this combination of robotic arms is bare metal, but Disney has made some new changes this time.
You will see that the joint part of it has been wrapped in white fiber material and wrapped like an inflatable pillow. When you try to press or hold the inflatable arm, it will deform accordingly, but then it will be immediately inflated. It’s the same as the big white robot in the movie.
It looks amazing, how can it be done? The mystery is at the junction of the internal mechanical joints, through the induction of a special inflatable joint with a pressure sensor, when you hold it, the sensor will feel the change of gas pressure and respond in time, that is, immediately fill the gas, so It allows you to see a robotic arm that can be restored to its original state.
The biggest advantage of this is that there is a good buffer protection between the robot arm and the person, so that the robot arm is not too stiff, and it also gives a warmer and softer sense of security. The conclusion drawn from the phenomenon that children need to embrace a sense of security.
At the same time, such a design also avoids the "horror valley effect". The white arm shape and design do not make the robot and human being too similar in appearance and movement, so as not to cause psychological fear. The feeling of special materials and soft texture can even enhance people's good feelings for robots.
Interesting places are not just here. In order to display more information on soft fiber materials, researchers use the built-in projector to project information, creating a special skill that allows information to float on the surface of the arm. You may remember that in the animation, there is also such a way of displaying information on Dabai.
In addition to the joint part, this time the finger part has also undergone some changes. You can see in the video that the fingers are all wrapped in rubber and look like a fat hand. Only 4 finger hands are actually created by 3D printing. Out, although the fingers are fat, but they can grasp the object sensitively and perceive the power.
If you look closely, the finger movement method is gradual. When the palm is holding the object, the contact test is first performed with one finger, and then the other fingers then re-evaluate the grip strength, so that the most suitable one is grasped. The pressure range, and therefore, the robot arm can gently grasp a very soft object, and with the algorithm adjustment, it is very possible to grab the raw eggs and the like in the future.
Speaking of the meaning of designing this robotic arm, Disney scientists said in the paper: "Our goal is to build a robotic arm system that can interact with humans and gently manipulate objects." This is not A simple goal, there may be some distance from the perfect white robot, but the reality of step by step from the animation makes us look forward to such a unique touch of the robot, which on the other hand shows that at least we are in science fiction animation What you see in your work is not completely fictional.
