Successfully completed and closed the R&D report for the grant: "Development of a gyroscopic echolocator for visually impaired people".The resulting prototype implements a unique concept of two-axis mechanical stabilization of the sensor relative to the surface, and has the best key indicators in its market segment.- During the concept improvement on 10 hardware iterations, a prototype of a software and hardware complex was developed that meets the requirements for reliability (more than 8 hours of continuous operation), efficiency (~75%), and accuracy (~83%);- Developed and optimized embedded software for the microcontroller in C++. A Madgwick filter was implemented, as well as dual-threaded execution on FreeRTOS. 99% stabilization accuracy was achieved (less than 1% of incorrect position corrections during operation) and 120 ms of hard real-time interval of device operation;- Using the KiCAD and Autodesk Inventor packages, kinematic models, printed circuit boards and mechanical designs of the device were developed, which made it possible to iteratively reduce the mass and dimensional parameters by more than one and a half times from those originally planned.
