Robotic third hand can blast through walls and collect fruit

Researchers from the University of Sherbrooke (Canada) have developed a robotic limb functionality which copies a human hand. Have a massage or lift over head rod with it until you succeed, but to break through the wall with a hammer or gently picking apples from the tree without problems. The system was developed in the framework of creating a universal set of extra limbs to exoskeletons of the future.

The arm has 3 degrees of freedom and uses a hydraulic drive, a magneto-rheological clutch and a hydrostatic transmission. To compensate for the power of hydraulics, the power unit is made in the side and delivers fluid through the tubes. The arm itself is mounted on the operator’s belt, near the center of mass of the body. Her work space is limited so not to accidentally hit a man in the face.

The weight of the arms 4 kg, it moves with the maximum efficient speed of 3.4 m/s – this corresponds approximately to the average person. Three-fingered manipulator can be replaced by another version, or to fix instead any tool weighing up to 5 kg. In the current version of the management is not the operator itself, and its remote counterpart with a joystick. This is the main minus – and plus the whole system.

As explained by the authors, there are two ways of transferring control to the third limb of the operator without restriction to his own hands. You should either create nanosensor able to read the mental commands, or put the module with the AI and sensors to assess the situation, to predict the actions of the operator and help him. This is too complex task, so the developers focused on the optimization of the hands, making it safe, efficient and easily managed.

Physicists have learned to turn plastic bottles in supercapacitors

Scientists from the University of California, riverside have developed a technology to produce components for supercapacitors from regular waste. We are talking about polyethylene terephthalate or PET, which is made most of plastic bottles. This material is from an economic point of view is significantly superior to high-tech raw materials, like graphene or carbon nanotubes. […]

Looks like a screwdriver of the XXI century

Recently Techcult wrote about the drill of the XXI century with a touchscreen and lasers. But the screwdriver is traditionally considered to be more simple, reliable and very straightforward tool. What similar high-tech screwdriver advanced Italian production? And it is similar to the Kinetic device Driver. Kinetic Driver designed by the Italian designer Giacomo Di […]

Our Solar system is most similar to space croissant

The sun emits powerful electromagnetic winds that envelop the planet in our solar system like a giant bubble. This magnetic bubble is called the heliosphere and protects the planet from dangerous space radiation. Scientists have long believed that the heliosphere is in the form of a comet – with a distinct nose and long flowing […]

Some homemade masks turned out to be more dangerous than no

Despite the fact that the industry has recovered from the shock of the first days of the pandemic COVID-19 and now produces enough facial masks of different types, most people in the world due to various reasons use homemade versions. Everyone understands that they are less effective than professional medical model, but the question is: […]
