14-year-old Oleksandra Maksymenko from Zhytomyr region assembled an ultrasonic smart-bracelet for the orientation of people with vision impairment and received an award at the all-Ukrainian competition of the Minor Academy of Sciences of Ukraine.
The student of Yosypivska gymnasium developed the device together with her computer science teacher, Arkadiy Petrovskyi. The high cost of ready-made analogs was the impetus: factory bracelets cost from 26 thousand hryvnias, so the schoolgirl ordered components on the internet and assembled her own version much cheaper.
The bracelet is worn on the arm and turned on with a button on the strap. The built-in ultrasonic sensor detects obstacles on the way and gives a warning sound signal.
Besides the bracelet, Oleksandra created an automated laser toy for kittens. In May 2026, this development received a diploma of the first degree at the ChildTechExpo exhibition-competition.
Now the developer and her supervisor are working on a new project – an automated system for counting people in the gymnasium shelter with the output of results on the screen.
