Harvard Octobot is the first autonomous soft robot

For years, robotics experts have been looking for the use of softer materials instead of the usual metals and plastics to create a complete soft robot. But from the Harvard University Octobot is the first time, not only does not contain the hard part, but it is also completely independent.
Robert Wood and Jennifer Lewis, researchers at the Harvard-Weiss Institute of Bioinspired Engineering, describe the nature of the Octobot. Future robots can handle rough terrain easily. This study shows that we can easily create a simple, complete soft robot, which lays an important part of a more complex design basis.

The robot is mainly 3D printing, after which the body is inlaid with two power sources and its movement channels. The movement is pneumatic, and the fuel of the robot is the resulting gas. It pushes fluid through the limbs and inflates them.
But the key point here is that the microfluidic network is cleverly designed to feed itself back into the pre-defined order after inflation. This feedback on its own does not require any researcher or environment to provide power or guidance.

Welded Bed Plate For Flanges Of Ship Pipe

The flange welded single-sided seat plate is mainly installed on the top, side wall and bottom of the cabin or cabinet as the entrance and exit of the cabin or cabinet. Valves, accessories or pipes can be installed directly on the single-sided seat plate.

Flange welded single-sided seat plate is suitable for seawater, fresh water, oil, air and steam pipelines below 300 °C. The commonly used nominal diameter is 15~150 mm, and the nominal pressure is lower than 1.6 MPa. The shape of the single-sided seat plate is similar to the corresponding lap-welded Steel Flange.

Flange welded double-sided seat plates are generally used when pipelines pass through decks and tanks, and the two sides of the seat plate are respectively connected to valves, accessories or pipes.
Compared with the single-sided seat plate, the double-sided seat plate has an extra shoulder and double-sided mounting stud bolts. The outer diameter of the shoulder is 10~20 mm larger than that of the corresponding flange, and the thickness of the shoulder is 6~12 mm.
Its scope of application and other structural dimensions are basically the same as those of the single-sided seat plate.
The manufacturing and installation methods of the flange-welded double-sided seat plate are basically the same as the single-sided seat plate, but when the screw holes are drawn, the positions of the upper and lower screw holes of the seat plate must be staggered from each other and must not overlap; deck or bulkhead The diameter of the hole on the top is 2~3 mm larger than the diameter of the seat plate.
