3D printer creates a hand that can play the piano

Recently, a 3D printing robot hand that can be flexibly operated and can perform various sports has been developed, and it can actually play the piano!

It was developed by researchers from the University of Cambridge in the UK and can play simple music on the piano.

At the same time, without changing the mechanical characteristics or materials of the hand, the robot can imitate the style of the piano playing, such as staccato and legato, the passive movement of the wrist, not the fingers.

The researchers 3D printed a soft, hard material that replicated all the bones and ligaments in the human hand. They were surprised to find out how extensive the range of motion was due to the mechanical design of the hand.

“We can use passive to achieve a wide range of robotic movements: for example, walking, swimming or flying,” said Josie Hughes, Cambridge University's first engineering author. “Intelligent mechanical design allows us to achieve maximum range of

motion with minimal control costs: we want to see how much movement the mechanic can get.”



“The basic motivation for this project is to understand the specific intelligence, the intelligence of our machinery,” said Dr. Fumiya Iida, who led the study. “Our body is made up of intelligent mechanical designs, such as bones, ligaments and skin, and

even without active brain control, it helps us to act intelligently. By using the most advanced 3D printing technology to print human soft hands, we can now explore The importance of physical design, isolated from active control, is impossible for human

piano players. The brain cannot be "turned off" like our robots."

3D printing technology has become more and more mature. We have seen the rapid development from printing toys to robots. Although the maturity of technology still needs time to test, we have to admit that 3D printing technology has penetrated into

our lives.

Although the 3D printing robot hand currently developed is limited, we believe that this method will promote further research on bone dynamics, so even if this hand can't complete the task, we believe that future researchers will be able to create more

advanced and Medical assistant who can actually operate.
