New Robot Cloth Developed In The US

A cloth robot with embedded sensors and capable of moving and telescoping will soon show its strength. They will help future robots get "tactile" skin, become a robot coat to enhance human strength and endurance, lighten the impact of pilots and astronauts on the voyage, and may become a useful assistant for human exploration of space.

According to physicist tissue network recently reported. In the cotton fabric that made up robots, researchers mixed sensors made of flexible polymers and linear drivers made of memory metal. Memory metal will curl and contract when heating up, so that the cloth will "move".

"At present, most" robot cloth "can only sense the signals emitted by electronic components through wires. But we have successfully integrated driving and sensing. U.S.A Rebecca Kramer, a professor of mechanical engineering at Purdue University, said: "we use sewing technology to sew linear drivers and sensors into cloth, so this technology has the potential to integrate into modern textile industry and scale production."

When the cloth robot is wrapped on the surface of the material such as foam plastics or balloons, it can drive the material to bend to and fro in the desired direction, push the material to move forward like an inchworm, and compress different parts to make creep and sliding.

The goal of this research is to develop a series of "soft robots" embedded in the retractable "skin". In the future, "skin" will embed more flexible, seismic resistant electronic components to adapt to space activities, which will effectively reduce the carrying weight of astronauts and spaceships. The technology can also be used for portable. Robot By covering the surface of the deformable equipment with a specific "skin" functional cloth, it can quickly assemble into a specific device suitable for interplanetary exploration.

"We can even design a machine suit for flies." Cramer said optimistically, "with the aid of the" outer skin machine ", any object can have the potential to become a robot.

The research team led by Cramer has submitted relevant papers to the International Conference on Intelligent Robot Systems held in Chicago, us. During the meeting, they also demonstrated a variable hardness fabric that can be used for medical support and mechanical manufacturing.

The shape memory polymerization fiber makes the fabric have the ability of changing hardness. The polymer will produce phase transformation after heating, make the material softer, and can be used for medical fixation in specific parts. The polymer surface is also covered with shape memory alloy, which can warm up the polymer material after electrified. This technology is expected to make robot technology more efficient and energy saving in the future.

Cramer said: "usually, mechanical hinge joints should be kept or kept at a specific location, which requires continuous consumption of large amounts of energy to prevent joint relaxation. And now, the new type. cloth The joints can be locked at low energy consumption.
