Information

In addition to the ability to grasp millimeter objects with precision, it has been given a smarter function.

If the ends of the paper-cut structure are replaced with PDMS material with ferromagnetic force, it can use remote magnetic field to quickly drive the small clamps on and off.

Let's see how it performs after being given a soul.

Yang Yilai did an underwater magnetic field test: put the small jig underwater with magnetic field, let the magnetic force of the ferromagnetic end (bottom) and the paper-cut structure in static equilibrium, throw a small stone underwater, when the stone touches the jig, it will disturb the static equilibrium, immediately present a "grasping" state, within 60 milliseconds with magnetic field precision to grasp the stone.

The study, "Graspingwith kirigami shells," was published in the recent May issue of Science Robotics. He said, "Compared to rigid manipulators, soft-body manipulators have limited strength, but they are more adaptable in both design and manufacturing, simple in structure, more also less costly, easily scaled in size, can be combined with traditional commercial robotic arms, and can also be made into convenient and portable gripping tools."

Jib Cranes

The working strength is light, consisting of column, slewing arm, slewing drive device and electric chain hoist. The lower end of column is fixed on the concrete foundation through the foot bolt, and the cantilever is driven by the cycloid reduction device to slew, and the electric hoist makes straight running left and right on the cantilever I-beam, and lifts heavy objects. The cantilever is a hollow steel structure, with light self-weight, large span, large lifting capacity, economic and durable. Built-in walking mechanism, using special engineering plastic wheels with rolling bearings, low friction, light walking; small structure size, especially conducive to improving the hook stroke. (The system can also be configured with domestic or imported full pneumatic hoists.) All specifications have a common advantage: light dead weight, long swing arm, high lifting capacity, easy installation, operation and maintenance. They are completely self-contained, making them an ideal workstation crane and suitable for outdoor yards and loading platforms. The fixed column footprint is small. Maximum lifting height can be obtained even for very small lifting clearances

Fully automated robots

An automatic manipulator that simulates manual operation. It can grasp and carry objects or manipulate tools according to a fixed procedure to complete certain specific operations. The application of manipulators can replace people engaged in monotonous, repetitive or heavy physical labor, achieve mechanization and automation of production, replace the manual operation of people in harmful environments, improve labor conditions, ensure personal safety, and therefore widely used in mechanical manufacturing, metallurgy, electronics, light industry and atomic energy and other sectors. Industrial production sectors, for picking and placing workpieces and loading and unloading materials in high-temperature, heavily polluted areas. Automatic manipulators are often used as add-on devices to machine tools or other machines, such as loading, unloading and transferring workpieces on automatic machine tools or automatic production lines, changing tools in machining centers, etc., generally without independent control devices. The application of automatic manipulators in the forging industry can further develop the production capacity of forging equipment and improve labor conditions such as heat and tiredness.
