Today I bring you a 4D printed tensegrity robot .
Researchers at Georgia Tech have recently used 3D printing to generate a series of small structures that can be thermally restored like a memory metal , from a compressed state to a rigid structure.
The research results were published in the latest issue of
nature-scientific reports上

4D printing robots
Traditional 3D printing belongs to the category of additive manufacturing, layer by layer superimposed material finally prints a three-dimensional three-dimensional shape.
So what does 4D printing mean?
Sounds great~~~~!
In fact, the extra dimension is the time dimension .
After a certain design, 3D printing is used to print the required structure into the material (programmable reconfigurability). When the whole material is heated, after a certain period of time ( cooking over time :D ), these structures that had collapsed to the ground are rejuvenated and churn to their feet.
Unlike the MIT team, the Georgia Tech team had some creative uses for the way the material was shaped. They introduced tensegrity into 4D printing.
The tension body is a very excellent mechanical structure, which is composed of rods and ropes , and maintains the stability of the structure with tension and tension.
Buckminster Fuller
Since the invention of the architect Buckminster Fuller in the 1960s, the tensile structure has been widely used in large buildings such as bridges and stadiums. It can be used for large building structures as well as small flexible structures.
Recently, it has also been experimentally proved that in the robot
Can be used as an efficient structure .
Tension Robot ( Portal )
Since the tension body is flexible and rigid, it can provide different motion modes for the robot to adapt to different environments.
The researchers used 3D printers to print the designed structures using shape memory polymers ( SMP ). The amazing thing is that researchers can program and print compressed materials according to different shapes required, and they only need to be ironed when they are used!
The material responds differently to different temperatures. It can go from a compressed state to an elongated state when the temperature is raised, but it can be recycled and can also return to a compressed state (glass transition) when the temperature is lowered.
In hot water, it takes only a few seconds to go from a compressed state to a functional structure.
Pour the water out and you're a new, hard, standing robotic structure.
See how his shape recovers at different temperatures
At the same time, the researchers also tried
Different tensioned overall structures
Use rope and elastic surface as links respectively.
Cool feeling, especially the second one~~
这样的结构制作方式对于软体机器人、变形材料以及太空中需要张开的天线、设备装置等具有重要的意义。在地面上可以用压缩状态包装运输，到了太空后再恢复工作的形状。极大的节约了运输空间，方便了大型结构和机器人的部署和应用。
让我们一起来看看这种4D打印的机器人结构吧！
