Developing software for a ground stationDevelopment of software for an unmanned aerial vehicle Propeller balancing software developmentDevelopment of an automatic mapping and autopilot assistance system based on camera imagesProgramming for drones on C, C++This is a low-level project, is associated with robotics. I worked with microcontrollers, drones, and special test bench for this. Also, I engaged UI for control. Developed and tuned algorithms for stabilization and control based on a mathematical model and PID. Automatic mapping of the locality with reference to the GPS coordinates. Precision balancing of propeller group. Shaking table. Stand study engine performance. Weather station with homing direction until long-range antennas. The most challenging stuff is under NDA.
