Focus Description:

Tie a piece of rope into a ring. Put this ring on the hands of one of the spectators. Invite him to modify the position of the rope, in other words, to make the ring "eight" without removing it from his hands. The volunteer, most likely, will not be able to do this. Then you will do it on his own hands, without removing the ring.

Trick with rope ring

Focus secret:

Lower the upper part of the ring down, wrap it around the lower one, lift it up and put the part on one of the hands from the same side. Remove the first loop from this hand. This will result in an "eight".

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy.

The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Blueberry crop improvement robot 28.07.2022

La Libertad is one of the regions producing and exporting more blueberries to Peru. However, the producers of this highly valued sour fruit in the world face a big problem: to determine the exact moment when the mass harvest of blueberries should begin. Errors in forecasts inflict many economic losses on the agro-industrial complex.

With this in mind, the Labinm Robotics research team from the private university Antenor Orrego (UPAO) is developing a prototype robot that allows you to sample a bunch of blueberries and use algorithms and artificial intelligence to know when the fruit should be ready.

“Agro-industrialists have their own harvest forecasts and therefore hire a lot of people for this period, but when the calculations do not work, you have to wait, and the cost of personnel and equipment still has to be assumed, which is why we decided to develop this prototype to give a solution,” said Sixto. Prado Garini, principal investigator at Labinm Robotics.

The specialist stated that the prototype, which is still under development in the laboratory, has four motorized wheels driven by calibrated, customizable and electronically supplemented by other cards, based on the power consumed by these elements.

In addition, it has two high-tech sensors that virtually capture the environment and assign a mathematical representation that allows you to direct work to the growing area to analyze the color and maturity of the fruit.

If there are 5000 blueberries on a bush, the robot will determine that 40% are ready for harvest in a week, and the rest in a week and a half. This is how he takes samples from the crop field and then we extrapolate the results. Said information is sent through the web application or satellite application because we provide industry 4.0 characteristics to it, and is sent to the company's managers for them to make a hiring decision.

Prado Garini assures that the goal of the technological projects he leads is not to destroy the work, but to complement and turn it into an improvement of the industry.
