Swiss researchers have developed the world’s first 3D-printed robotic hand with bones, tendons, and ligaments

 

In a breakthrough that could pave the way for the development of a new generation of prosthetics and robotic devices, Swiss researchers have created the first 3D-printed robotic hand with bones, tendons, and ligaments.
 

The delicate structure of the hand, which is composed of soft polymers, was created by researchers at ETH Zurich in Switzerland using a combination of 3D printing and a novel laser scanning method. Compared to earlier robotic hands, which usually used stiff materials and required external motors to move, this is a major advancement.

 

The newly developed robotic hand can pick up small objects, manipulate tools, and carry out a multitude of other tasks. According to the researchers, the hand may find use in robotics, rehabilitation, and prosthetics, among other fields.

 

The creation of the tendons and ligaments that enable the robotic hand to move naturally was one of the main development challenges. The researchers precisely modelled the internal structure of the hand using a novel laser scanning technique. The 3D printing procedure was then directed by this model, guaranteeing that the tendons and ligaments were positioned correctly.

 

Additionally, the researchers created a new software algorithm that enables the robotic hand to adjust to various tasks and learn new ones. The foundation of this algorithm is a technique known as reinforcement learning, which enables the hand to grow better over time by learning from its errors.

A noteworthy advancement in the field of robotics is the creation of the 3D-printed robotic hand. It is the first time that a robotic hand with this intricate and lifelike structure has been produced by scientists. This discovery may result in a new generation of robotic devices and prosthetics that are more adaptable and natural-looking than ever.

 

Currently, the goal of research is to increase the hand's dexterity and add new functions, like temperature and pressure sensing. Additionally, they want to create a system that will let the user control the hand with their thoughts.

 

In summary, the 3D-printed robotic hand is an incredible technical achievement that has the potential to completely transform the prosthetics and robotics industries. This discovery may lead to more independent and satisfying lives for those with disabilities. Additionally, it might create new opportunities for robotic devices in a range of industries, such as manufacturing, exploration, and healthcare.
