In a study published in the Science Robotics magazine, researchers showed that the sensors work well enough to allow a robotic to touch a delicate berry and handle a pingpong ball without squashing them.
“This technique puts us on a road to a day that gives robots the type of sensory functions found in human skin,” said Zhenan Bao, from Stanford University, USA.
The fingers of the glove sensors simultaneously measure the intensity and direction of pressure, two qualities necessary to achieve manual diligence, researchers say.
They still need to improve the technology to automatically control these sensors, but when they do, a robot wearing the glove can have the skill of holding an egg between the thumb and index finger without crushing or letting it slip.
The electronic glove imitates how the layer of human skin cooperates to give our hands its extraordinary sensitivity.
The upper and lower layers are electrically active. The researchers put a grid of electrical lines on each of the two facing surfaces, which rows in a field, and twist these rows perpendicular to each other to create a dense set of small sensing pixels.
They also made the bottom layer harsh as the spinosum.
To test their technology, the researchers placed their three-way sensors on their fingers in a rubber glove and put the glove on a robot hand.
Wi-Fi Booster meets smart speakers
Sep 1, 2018
The NetGear Orbi Voice Network has finally come up with something we had dreamed about for a long time, a smart speaker and wireless network router in the same device. This unit packs a 3.5 inch forward-facing woofer and an inch of tweeters on top. It offers a tri-band WiFi network that extends up to 4500 square feet. It’s certainly more expensive than other smart speakers out there, but it prevents you from investing in a WiFi booster and smart speakers separately. (Imagie: www.netgear.com)
