Bionic arm capable of playing the piano, developed to imitate the human hand

Bionic arm capable of handling eggs and playing the piano, developed to mimic the human hand, can “speed up the introduction of robots into our daily lives”

  • The robot arm has been developed by the Korea Institute of Machinery and Materials
  • It has four fingers and each finger has three joints, making it incredibly flexible
  • This allows robots to ‘interact physically with the world in a meaningful way’

A bionic arm capable of handling eggs and playing the piano, developed to mimic the human hand, could “accelerate the introduction of robots into our daily lives.”

Developer Dr. Hyunmin Do of the Korea Institute of Machinery and Materials says that the incredibly handy hand can also pour water and handle scissors.

The device consists of four fingers, each with three joints – making them as flexible as a human hand but with a stronger grip.

It uses 12 motors to make it move in different directions and the grip can be changed depending on the item it is holding or manipulating.

The team says it could be used in factories or industry and enable robots to “physically communicate with the world in a more meaningful way.”

The bionic arm weighs just 2.2 pounds and is strong enough to lift an object three times as heavy as itself, the team confirmed.

“The robot hand has been developed to handle various objects, including the tools in daily life, by mimicking the delicate movement of a human hand,” said Dr. Do.

‘It can process eggs or cut paper with scissors. It is comparable to a human hand in size and movement. It is lighter and stronger than commercially available. “

The hand uses two types of sensors, half an inch wide and weighs less than a fifth of an ounce, which are able to distinguish between different feelings of power and touch.

They fit on the fingertips, fingers and palm and can detect that the hand comes in contact with almost any object.

“The sensors are the key to controlling the grip force,” Dr. said. Do.

‘The hand can easily be mounted on different robot arms. It offers the world’s strongest grip against its own weight. “

It works in the same way as human hands by mimicking the structure and movement of actual fingers. A total of 12 motors move each finger and joint independently.

The team expects it to be used in industrial locations, but also in daily life.

Better bionic hands are the ‘holy grail’ of robotics. People can easily manipulate all kinds of objects, but robots need better mechanics and more intelligence.

The next generation must be extremely handy, but also easy to build.

They are getting pretty good at moving, but despite these new skills, they still have a major weakness.

The most talented of the set can still be stopped in their tracks by a simple doorknob, as they cannot grasp or rotate the circular object.

Dr. Do hopes that his invention will accelerate the inevitable introduction of AI and robotics into our daily lives, and not just in industry.

His team developed a unique mechanism to support movement in small spaces with a high degree of freedom – comparable to the movement of a human hand.

They modified the drive unit responsible for finger movements by embedding it in the palm.

Tastile skin type sensors, developed through joint research with the National University of Seoul, were also attached to the fingers and palm.

“These measure the force distribution on the contact area when the robot hand touches an object,” Dr. said. Do.

Commercial bionic hands developed so far have limited applications.

There are no products equipped with both the drive units embedded in the palm area and the built-in tactile sensors.

WILL YOUR JOB BE TAKEN BY A ROBOT?

Physical tasks in predictable environments, including machine operators and fast food employees, are most likely to be replaced by robots.

Management consulting firm McKinsey, based in New York, focused on the number of jobs that would be lost due to automation, and which occupations were most at risk.

The report said that data collection and processing are two other categories of activities that can increasingly be done better and faster with machines.

This can displace large amounts of labor – for example, in mortgages, paralegal work, accounting, and back-office transaction processing.

Conversely, jobs in unpredictable environments are the least risky.

The report added: “Professions such as gardeners, plumbers or providers of childcare and elderly care – will generally see less automation by 2030 because they are technically difficult to automate and often pay relatively lower wages, making automation a less attractive business is proposition. “
