This electronic glove can & # 39; gives robots sense & # 39; human contact

BOSTON: Scientists of & # 39; Stanford developed an electronic glove which some robotic hands off sensors can give a sense of & # 39; contact and human dexterity.

In a study published in the journal Science Robotics, the researchers showed that the sensors work well enough to allow the robotic hand touching delicate berry and handle ping-pong ball without coming off.

"This technology tqiegħedna road for one day to give robots the type & # 39; sensitive capabilities found in human skin," says Zhenan Bao, from the University & # 39; Stanford in the United States.

The sensors in the finger tip of the glove simultaneously measure the intensity and direction of pressure, two essential qualities to achieve manual dexterity, the researchers said.

They still perfecting the technology to automatically control these sensors but in doing so, robot wearing the glove can & # 39; have the dexterity to hold egg between the thumb and forefinger without exceeding or leaving it slippery.

The electronic glove mimics the way the human skin layers work together to give a hand to their extraordinary sensitivity.

Layer & # 39; out of our skin is equipped with & # 39; sensors to detect pressure, heat and other stimuli, researchers said. Fingers & # 39; and our palms are particularly rich in & # 39; & # 39 sensors; contact.

The study Postdoctoral Clementine Boutry and student master Marc Negre led to the development of electronic sensors that mimic human mechanism.

Each sensor on the finger tip & # 39; of & # 39; robotic glove is composed of three layers flexible work together.

The layers & # 39; & # 39 and over; below are active with electricity. The researchers set up a grid & # 39; electrical lines on each of the two surfaces facing & # 39; forward, as rows on the field, and turn these rows perpendicular & # 39; another to create a dense array of & # 39; Small sensing pixels.

They also made the bottom layer of bumpy like spinosum.

To test their technology researchers put their sensors & # 39; three levels fingers & # 39; a & # 39; rubber glove, and put gloves on robotic hands.

Eventually the aim is to incorporate the sensors directly into & # 39; under the skin covering a robotic hand.

F & # 39; one experiment, they programmed the robotic hand that you wear gloves to touch a cow way unharmed. also nicknamed Ipprogrammaw hands to lift and move the ping-pong ball without crushing them, using the sensor to detect the proper crack force to seize the ball without dropping & # 39 ;.

With appropriate programming, robotic hands being wears the glove to hit the actual contact can & # 39; to perform a repetitive task such as egg lifting the carrier strap and placing them in & # 39; boxes Cardboard.

The technology can & # 39; also have applications in & # 39; operation at robotics, where a precise control over the contact.

However, the ultimate goal is to develop an advanced version of the glove automatically applies just the right amount of force to manage safely item without prior programming.

"We robotic hand to touch raspberry to process without crushing it, but we & # 39; away to be able to touch and find out which is raspberries and let the robot to recover," said Bao.
