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. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. 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. ... >>
Random news from the Archive Robot vegetable grower Dragonfly with laser weeding
19.01.2024
Swiss startup Caterra has unveiled a new robot, Dragonfly, that independently navigates vegetable fields and uses lasers to effectively control weeds. This technological breakthrough promises to reduce the high cost of manual weeding, which costs vegetable growers significant labor and financial costs.
The Dragonfly robot promises to revolutionize agriculture by providing an effective and technologically advanced weed control solution that will ultimately improve the productivity and efficiency of farming operations.
In organic carrot fields, hand-weeding crews spend between 80 and 350 hours per hectare, depending on the severity of weed infestation. Not only is it expensive, but it also requires a lot of manpower at the same time.
Dragonfly, weighing less than 100 kilograms, is equipped with electric motors and four massive bicycle wheels, and uses GPS technology for orientation. The robot is equipped with cameras to recognize weeds and a laser that precisely destroys unwanted plants. At the moment, the speed of the device is limited, but the team of engineers is constantly improving the algorithms, trying to achieve weeding one to two hectares per day, including at night.
It is important to note that the use of laser is minimally harmful to only 1-2% of carrots.
Currently, several robots equipped with cameras monitor farmers' fields, photographing plants to train artificial intelligence to distinguish between carrots and weeds.
Vegetable growers are showing great interest in this unique laser labor method, offering their fields for testing. The more test areas available for photography, the more effective the robot's learning algorithms are.
