Scientists have created an easy exoskeleton with artificial intelligence
Researchers from Stanford University have developed an exoskeleton with sensors and artificial intelligence algorithms designed to improve its characteristics. Technology Review writes about this.
The robotic device resembles a boot. It was equipped with inexpensive wearable sensors, a Raspberry Pi single -paying computer operating from the battery.
The data generated by the boot is analyzed by the machine learning model. She sets up the device and moves the ankle, replacing some functions of the calf muscle. Thanks to this, the leg pushes away from the ground and takes a step, allowing the owner to walk faster with less effort.
According to the developers, AI-model is personalized in just one hour. During operation, the algorithm reaches out, adapting to a change in user behavior.
During the testing, the developers found that the use of the device increases the speed of 9% and reduces energy consumption by 17% compared to natural movement in ordinary shoes.
On the treadmill До Квон біжить , the device turned out to be twice as effective as similar devices. Researchers compared the energy conservation and increase in speed with the “removal of a 14-kilogram backpack”.
According to developers, existing exoskeletons are difficult to adapt to an individual user due to bulky. They are also expensive and rarely show a positive result outside the laboratories.
Stanford noted the size and weight of their development. According to them, the device for the first time demonstrates the ability of an exoskeleton to save human energy in real conditions.
Scientists hope that development will help the elderly or experiencing problems with muscles to move more freely.
“This would be very useful for those who may not be so strong and want to go a little further,” said the head of the center of advanced robotics at the University of London, Queen Maria Caspar Altopher, who did not participate in the study.
In the future, scientists plan to test the device on older people and commercialize the product.
“We hope it will be a little like an electric bike. He does not do all the work for you, but requires the application of acceptable efforts, ”said one of the authors of the project Patrick Slade.
Recall that in January 2022 an eye implant with artificial intelligence returned his eyesight 88-year-old woman.
In March 2021, scientists showed AI-Ryukzak to help visually impaired people to navigate in space.
