Clone Robotics unveils robotic arm with muscles and skin

Clone Robotics demonstrated its latest development – a robotic arm, which is designed to resemble a human as much as possible. This arm has muscles that are covered with synthetic leather. The muscles were developed by the Clone Robotics team and were based on the idea of ​​the inventor McKibbin, which was used in prostheses back in the 1950s. In fact, such muscles are mesh tubes, inside of which are balls filled with air. An external pneumatic or hydraulic pump inflates the ball, it expands, and as a result, the muscle contracts in the longitudinal direction.

But the creators of the robotic arm did not want to make the pump too bulky and were looking for a design that could simply be applied with an electric current and made it contract. So they filled the balloons with a liquid – acetaldehyde – and placed a heating element in them. When an electric current is applied to it, the liquid boils and the pressure inside the ball increases by more than 6 times. This allows the muscle to contract “impressively fast,” the developers note. The prototype arm is covered in translucent skin so that the movement of the muscles can be seen.

As for the “skeleton” of the hand, it consists of artificial “bones” resembling human ones, on articulated joints to provide a range of motion as close as possible to a human. The developers claim about 27 degrees of freedom: for example, the hand can naturally move the wrist, rotate the thumb, etc., all of which are driven by a complex combination of muscles and tendons. During the tests, the hand was even able to lift a dumbbell.

By the end of 2022, Clone Robotics plans to ship such robotic arms to customers. At the same time, the cost of the device has not yet been reported. With their next product, the company is going to make a full torso with a stiff spine that includes 124 muscles in the neck, shoulders, arms, chest and upper back. He will ride on a platform with a battery.

Fans of top Samsung tablets will have to wait The

Samsung has postponed the launch and even the start of the development process of the new flagship Galaxy Tab S9 tablets.

The source says that the company originally planned to start development in December, but now it has been postponed until next year. That is, new models will not be able to come out at the beginning of 2023. Recall that the Galaxy Tab S8 line debuted in February.

When exactly the new tablets will be released is unknown. Perhaps they will be presented at the end of August at the Unpacked event, where new folding smartphones are usually announced.

Changes in Samsung’s plans are due to the situation in the market. In particular, falling demand for mobile devices and PCs.

The decline in demand is also expected to disrupt Samsung’s plans to manufacture and ship tablets this year. Late last year, the company set a target of 400,000 S8 Ultra models, 900,000 S8 Plus models, and 1.2 million base Tab S8 models.

The iPhone 14 Pro Max performed great but still fell

DxOMark specialists tested the power subsystem of the iPhone 14 Pro Max.

The device earned 133 points, taking 15th place in the overall rating. For comparison, the iPhone 13 Pro Max scores 136 points.

Considering that the iPhone 13 Pro Max easily put any flagship of last year on the shoulder blades, the iPhone 14 Pro Max is unlikely to disappoint anyone with its autonomy.

If you look at the results in more detail, then there is some noticeable difference just in points for autonomy: 151 points for the new model versus 156 points for the previous model. In more familiar terms, this is 2 days 17 hours and 2 days 20 hours of work in the source test. At the same time, the devices are charged almost identically.
