ETH succeeds in printing robot parts with different polymers and new laser scanning technique

by

Scientists at ETH have succeeded in printing a robotic hand with bones, ligaments and tendons made of different polymers using a new laser scanning technique. It is believed this is the first time such materials and techniques have been used.

3D printing is advancing rapidly, and the range of materials that can be used has expanded considerably. While the technology was previously limited to fast-​curing plastics, it has now been made suitable for slow-​curing plastics as well.

These have decisive advantages as they have enhanced elastic properties and are more durable and robust. [Read more…] about ETH succeeds in printing robot parts with different polymers and new laser scanning technique

High-energy shape memory polymer could enable robots ‘flex their muscles’

by

A high-energy shape memory polymer could someday enable robots to “flex their muscles”, according its developers.

When stretched or deformed, shape memory polymers return to their original shapes after heat or light is applied.

These materials show great promise for soft robotics, smart biomedical devices and deployable space structures, but until now they haven’t been able to store enough energy. [Read more…] about High-energy shape memory polymer could enable robots ‘flex their muscles’

Celanese suggests replacing metal parts in robots with polymers

by

Choosing materials is one of the most important decisions when designing and building a machine such as a robot, particularly one that moves around, like an autonomous warehouse robot or an automated guided vehicle. 

Most of the machines this website features in its articles and advertising use metals for the vast majority of their components. Even the outer casing on most industrial robots tends to be a metal such as iron or steel.

However, according to an expert at Celanese, one of the largest materials companies in the world, the vast majority of components and parts that are currently made out of metal can actually be replaced with polymers or thermoplastics.

Automation increases productivity in materials science by 384 times, say researchers

by

An automated method of conducting materials science research can increase productivity by 384 times when compared to a human, according to researchers. 

The robot-plus-software system also makes it easier for people who are not expert researchers or scientists to create new materials.

A Rutgers-led team of engineers has developed an automated way to produce polymers, making it much easier to create advanced materials aimed at improving human health. [Read more…] about Automation increases productivity in materials science by 384 times, say researchers
