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 Soft robotics for agriculture
02.10.2021
"Soft" robots are made of malleable materials such as silicone and other polymers, rather than metal. These materials give the robots organic characteristics, replicating the work of muscles and allowing them to move and do work instead of a human that old metal machines can't.
A particular application of soft robotics that I was interested in was agriculture. Most automatic harvesting solutions only deal with large and hard crops. There are several mechanisms for picking smaller crops, but many are tough and can damage the plant in the process. Some success has come from companies such as Soft Robotics Inc, which have created grippers with soft features. But they were still only able to work with harder crops. These difficulties led to a research project in which I participated. The aim of the project was to explore the possibility of autonomous picking of light fragile berries, in particular raspberries. This task required a unique grip. Given the fragility of raspberries, this problem could be solved with the help of soft robotics.
The idea that arose was to create a tubular structure that would move towards the berry bush and separate each raspberry from its neighbors.
The end effector slides up the stem of the berry, after which the soft robotic bags come to work, which do not directly capture the fruit. Instead, they lightly press on the back of the berry, which connects to the plant's peduncle. Then the entire tube moves away, displacing the berry from the stem. It is similar to how a person pulls a berry with his fingers.
The innovations associated with the creation of robots that resemble the human body coincide with the development of the brain of robots. Advances in artificial intelligence are allowing machines to detect feelings like happiness and sadness in speech. Research is also focused on developing computer vision technologies that can detect emotions by analyzing facial expressions.
