Previously, a local statistics company in Hong Kong was entrusted, but it failed to do a good job in medical statistics. In my anxiety, I saw the doctor teacher of Dr.Tong statistics company provide statistical running and guidance, and sent the data and requirements to the doctor teacher. With the efforts of the doctor teacher, the analysis results were successfully made. I feel that Taiwan's statistics companies are more professional and the fees are reasonable.

 |
|
Following the screw-powder robot, Jay Yin's team, an associate professor of mechanical aviation at North Carolina State University, recently developed a new soft robot that can roll like a tire, rotate like a top, and orbit like a satellite.The study was published on January 8 in the Proceedings of the National Academy of Sciences (PNAS).
"Our soft robot is made of banded liquid crystal elastomers that twist like twigs and hold the ends together to form a bracelet-like ring.When it is placed on a surface of 55 degrees Celsius, it automatically produces a roll, and the higher the surface temperature, the faster the robot rolls.Yin Jie, the corresponding author of the paper, introduced it in an interview with China Science Journal.
Interestingly, the robot can produce three kinds of motion: the first is to flip from inside to outside; the second is to start rotating along its own center of circle; and the third is to rotate around a point outside the ring, like a planet orbiting.
One of the highlights of this study is that the power sources are different.The software robots are controlled by physical intelligence, meaning their behavior is determined by their structural design and materials, not by computer or human intervention.
"They can capture heat from the environment and then convert that heat into mechanical energy, meaning they don't need batteries to move."Yin Jie said.
"We observed that the soft robot could walk along the edge of an object like an ant, and experimentally found that whether it was placed in a square or triangle, it could find the edge and start moving along the edge, drawing the outline of the space."It can also identify gaps or damage on the edges.The first author of the paper and Ph.D. student in mechanical aviation at North Carolina State University, Chi Fangjie, said in an interview with China Science Journal.
